Geological resources and environment should include geological resources and environmental geology. Geological resources refer to the space for human survival and basic materials such as rocks, minerals and water. Environmental geology is to study the internal relations between natural geographical environment, geological environment, water environment, soil environment, meteorological environment, geochemical environment and biogeochemical environment, which are composed of water, soil, light and heat. In the research process of agricultural geology, based on the traditional agricultural production mode based on soil, we first realize that rocks are also the place where crops grow, especially high-quality agricultural products have strong selectivity and dependence on geological environment, and draw the conclusion that developing geological environment to produce high-quality agricultural products. The second is to develop ordinary silicate rocks and extract multi-element and low-dose ionic liquid mineral fertilizer as a whole, which is named as gold grain foliar fertilizer. During the development process, the comparative research experiment of farmland seed value was carried out for 4 years, which verified that the fertilizer can really improve the yield of food crops, thus realizing the double breakthrough of developing and utilizing ordinary rock resources and improving the yield of food crops. Therefore, it is considered that the development potential of geological resources and environment is huge, and the development results will provide more high-quality agricultural products for human beings, produce greater economic, social and environmental benefits, and serve sustainable development.

The development of agricultural geological resources and environment is intrinsically linked with the development of agricultural economy. After more than 20 years of hard exploration and practice, agricultural geologists have proved that the economic level of agricultural production can be effectively improved. Because the combination of geology and agriculture is a new thing, a complete scientific system has not been established, and the social status has not been firmly established. It is difficult to popularize and apply agricultural geology, and a lot of work needs to be done to get social recognition. The most critical problem is that if leaders want to use agricultural geological research results to complete government work, they must first develop social resources, use agricultural geological scientific and technological achievements, improve people's attention to the development of geological resources and environment, and push agricultural geological work deeper.

1 characteristics of agricultural eco-geological environment in Guizhou

Lithostratigraphic characteristics 1. 1

After several billion years of development, pre-Sinian silicate rocks with a thickness of 20,000 meters, pre-Sinian silicate rocks that have undergone regional metamorphism, Sinian to Cretaceous silicate rocks and carbonate rocks with a thickness of about 654.38+00,000 meters, and igneous silicate rocks in different historical periods have been deposited on the land of 6,543.8+076,000 square kilometers in Guizhou, and the loose accumulation layer is 0-20 meters thick. ..

1.2 rock distribution characteristics

(1) distribution area. Pre-Sinian regional metamorphic silicate rocks, with a distribution area of about 30000km2. The distribution area of silicate rocks and carbonate rocks deposited from Sinian to Cretaceous is 140000km2, of which carbonate rocks are about 1 10000 km2, accounting for 6 1.9% of the national territory. The distribution area of igneous silicate is about 6000km2, and basalt is the most widely distributed. Quaternary loose accumulation layer has the widest distribution area, mainly covering slopes and depressions exposed by strata in various periods, accounting for 70% ~ 80% of the national territory. The loose nature of loose accumulation layer determines the intensity of human reclamation. More than 56 million mu of cultivated land in Guizhou is mainly developed on the youngest geological body.

(2) The strata are distributed from east to west, from old to new. Metamorphic rocks 600 million years ago were concentrated in southeastern Guizhou and Fanjing Mountain, and extended westward to southern Guizhou, central Guizhou, northeastern Guizhou, northern Guizhou and northwestern Guizhou to Chishui. The basic pattern conforms to the distribution law of Sinian-Cambrian-Jurassic-Cretaceous.

(3) In southern Guizhou, central Guizhou, northeastern Guizhou, northern Guizhou and northwestern Guizhou, silicate rocks and carbonate rocks are basically interbedded in strips.

(4) Basalt is mainly distributed in Bijie area and Liupanshui city in northwest Guizhou, with a small amount in central Guizhou.

(5) The distribution of carbonate rocks accounts for 665,438 0.9%, which forms the characteristic that Guizhou is dominated by karst agricultural ecology.

(6) Guizhou is a mountainous province, there is no large area of Quaternary loose deposits, and the most rocks are exposed to the surface, which is a major feature of Guizhou Province.

1.3 rock types and weathering characteristics

(1) Rock types: silicate rocks and carbonate rocks. See table 1 for further breakdown.

Table 1 Statistical Table of Rock Types and Mineral Compositions

sequential

(2) Weathering characteristics: The weathering products of the two types of rocks are quite different, resulting in different soil environments. Silicate rocks have weak weathering resistance. After weathering, sometimes the rock-soil boundary is difficult to distinguish. Rock is soil, and soil is rock. Weathering results show that sandy soil, clayey silt and gravelly sandy soil, which are mainly composed of silicon and aluminum, form soil layers in bare rock areas at a faster speed, which is generally not counted. Carbonate rocks are mainly dissolved, and a lot of calcium and magnesium are lost during weathering, and the rest is mainly clay. After weathering of carbonate rocks, the boundary between rock and soil is very clear, the formation speed of soil layer is about 1.0000 years, and the accumulation is about 1cm.

2 Guizhou agricultural eco-environmental characteristics

Ecological environment includes natural geographical environment, geological environment, water environment, soil environment, meteorological environment and geochemical environment. It is composed of water, soil, light and heat, and their functions are concentrated on the interface of the earth's crust surface. According to the report of agricultural resources in Guizhou in 2000, the natural factors affecting the sustainable development of agriculture in Guizhou counties were analyzed and compared. Eight quantitative indicators are adopted, including ① average slope of the ground, ② heat condition with temperature of 65438 00℃, ③ light condition, ④ moisture condition, ⑤ flat dam, hilly land, ⑤ rocky desertification area ratio, ⑧ forest vegetation, ⑧ soil erosion and * * *. 19 counties with good natural conditions; 46 counties with moderate natural conditions; Nine counties with poor natural conditions. This is an example of comprehensive factors of environmental geology, which provides a reference for discussing the agricultural ecological characteristics of Guizhou, but it is a pity that the important factors of geology are lacking, and the comprehensive evaluation will be more perfect if geological conditions are added.

2. 1 Comparative advantage

(1) Advantages of biological resources. There are more than 500 species of edible plants, 40 species of crops, 40 species of vegetables, 27 species of fruit trees, 500 species of fungi, 3,700 species of medicinal materials and 6 species of dominant trees in Guizhou.

(2) Agricultural products with local characteristics. High-quality rice and protein corn, "double low" high-quality rape, potato, bitter buckwheat, famous tea, high-quality pepper, out-of-season vegetables, famous fruits, spice products, Chinese herbal medicines, selenium-enriched agricultural products, economic trees and so on.

(3) Guizhou has a good climate, with annual average temperature 14℃ ~ 18℃, shovel accumulated temperature of 3500 ~ 5500℃, frost-free period of 260 ~ 330 days, and annual average rainfall11.

(4) Agricultural minerals such as coal, pyrite, phosphate rock, dolomite, limestone, potassium-bearing rocks, glauconite, selenium-rich rocks and seasonal sandstone are quite rich.

(5) The cultivated land area in Guizhou is about 56 million mu, and the per capita share is about 1.5 mu. It has the following advantages: it is distributed in subtropical zone, with mild climate and good hydrothermal conditions; The three-dimensional ecological environment in mountainous areas is diverse; There are various parent materials and soil types; The amount of chemical fertilizers and pesticides is small.

2.2 Comparative disadvantage

(1) The forest coverage rate is low, accounting for 20.86% of the national territory. Soil erosion is serious, accounting for 43.6% of the national territory.

(2) Land resources are abundant, but the quality of cultivated land is poor. 86% of the cultivated land is less than 1m, and 40% of the cultivated land is less than 15cm. Low-and medium-yield fields account for 78.6% of the cultivated land area. Cultivated land with a slope of more than 25 degrees accounts for 20% of the province's cultivated land. No soil loss leads to the decrease of cultivated land at the rate of 1 14000 mu per year. Coupled with the population expansion, the total population in 2000 was 35 million, and 2.74 million people did not have enough food and clothing, and the rate of returning to poverty reached 20%.

(3) "Groundwater is rolling, surface water is as expensive as oil", 3.8 million people in rural areas have difficulty drinking water, 50% of the fields and 30% of the soil are irrigated with guaranteed irrigation and semi-guaranteed irrigation, and most of the fields depend on the weather for food.

(4) The karst area in the whole province is 6 1.9%, and the objectively existing karst landform and rocky desertification area account for 12.8% of the national territory, which makes the ecological environment in Guizhou fragile, with low carrying capacity, weak ability to resist natural disasters and increased dependence on climate resources. There are also 20.832 million mu of rocky desertification land, accounting for 7.9% of the province's land area.

(5) The average slope of the whole province is17.78,6. The following accounts for 13.5%, 6 ~ 15. Accounting for 26.85%, and the temperature above 15 accounts for 59.65%. The average elevation of the whole province 1 1 100 m, 4.75% is below 500 m, 78.96% is between 500- 1500 m, and 1500m is above 16.47%.

(6) Uneven horizontal distribution of climate resources leads to diversity change; Less sunshine and insufficient sunshine resources; Disasters such as late spring cold, summer drought, floods, hail, autumn wind, continuous rain and so on occur from time to time.

3 the relationship between geological disasters and agricultural production

3. 1 Types and types of geological disasters

(1) Types of geological disasters. Geological disasters are one of the disasters that endanger human survival and development caused by the deformation and displacement of geological bodies. They are the biggest disasters that destroy resources and harm the environment, and belong to the category of environmental geology. Geological disasters are classified according to their causes, which can be divided into natural dynamic type formed by natural dynamic action and artificial dynamic type formed by artificial dynamic action, both of which are called compound type. According to the movement speed after the formation of geological disasters, it can be divided into sudden and gradual.

(2) Disaster species. Natural dynamic type is the main type of geological disasters, which is widely distributed in this area. The artificial power type is mainly developed in cities, traffic construction and groundwater exploitation areas. Compound is the geological disaster seen by the party. According to the investigation, there are 20 kinds of disasters in Guizhou, such as collapse, landslide, debris flow, foothill accumulation, erosion, weathering, collapse, ground fissures, loss of mineral resources, gas explosion, gangue accumulation, dangerous reservoirs, ground subsidence, ground subsidence, soil erosion, karst collapse and karst waterlogging. In a narrow sense, geological disasters only refer to collapse, landslide, debris flow, collapse, ground fissure, mine water inrush and ground collapse.

Sudden geological disasters occur in individuals and groups, including collapse, landslide, debris flow and land subsidence. Some have short duration, strong explosive force, rapid disaster, transformation and induction. For example, 1988 and 1995, the Sunshine Factory and Kaiyang Phosphate Mine collapsed, landslides and mudslides. Progressive geological disaster is a kind of chronic geological deformation, which is caused by physical, chemical, mechanical and biological variation and migration. The area is large and the scope is wide, and the harm is gradually aggravated, resulting in the deterioration of the ecological environment and the greatest harm to agriculture. For example, soil erosion and rocky desertification in western and southern Guizhou lead to fragile ecological environment.

3.2 the relationship between geological disasters and agricultural production

According to the investigation results of geological disasters in Guizhou, it has done harm to the national economy, social development and the safety of people's production and property to varying degrees. Among the types of geological disasters, the destructiveness of geological disasters in a narrow sense is expounded. According to the attributes and types of geological disasters, this paper introduces the relationship between geological disasters and agricultural production.

(1) Water and soil loss: Water and soil loss is a geotechnical loss disaster caused by meteorological disasters acting on geological bodies, which has the characteristics of large area, long time and weak intuition. Only by long-term monitoring or analysis and calculation of remote sensing information can reliable data be provided. Guizhou has a land area of 6.5438+0.76 million km2 and a soil erosion area of 6.65438+0.6 million km2, accounting for 35% of the land area. The amount of soil erosion in the whole province is 285.56 million t, and the nitrogen loss from the soil is as high as 250 thousand t every year. Western Guizhou is the hardest hit area of soil erosion. Weining County has a land area of 6925km2 and a soil erosion area of 4236km2, accounting for 67.3% of the land area. Hezhang County has a land area of 3249km2, with soil erosion area of 2 156.5km2, accounting for 66% of the land area. Jinsha county has a land area of 2528km2, with soil erosion 1 109 km2, accounting for 43.88% of the land area and 4.69 million tons of quicksand. The land area of Liuzhi Special Zone is 1792km2, and the soil erosion area is 1043km2, accounting for 58.2% of the land area. The amount of quicksand is 310.8 million tons, the annual amount of quicksand per mu is 2.8 tons, water is 36 tons, nitrogen is 0.87 kg, phosphorus is 0.55 kg, and organic matter is 7.6 kg. Soil erosion modulus covers an annual area of 4,307 t/km2, with an average loss of 530,000 t of sediment, 0/567,300 t of nitrogen/kloc, 0/000-40,000 t of phosphorus/kloc and 41352,000 t of organic matter. The annual cultivated land in the whole province decreased by 1.330 ha( 1.955 mu). (The above data comes from Resource Development and Ecological Construction (200 1) compiled by the Economic Committee of Guizhou Provincial Political Consultative Conference and the Agricultural Resources Division Office of Guizhou Province. )

From the above, it can be seen that under the specific natural geography and geological environment conditions in Guizhou, the soil erosion disaster is quite serious, which leads to the reduction of cultivated land, the thinning of soil layer, the loss of fertilizer, the accumulation of sediment in rivers and lakes, water pollution and accelerated eutrophication.

(2) Debris flow: Its occurrence is also closely related to climate. Most of them occur in areas where the slope of geological bodies is unstable in rainy season. At the beginning of 1989, there were 50 mudslides in the whole province, the scale was 10000 ~ 10000 m3, the land was washed away 15000 mu, hundreds of houses were built, and more than 50 people were killed or injured/kloc-0. During the period of 1994, the geological disasters in Guizhou were investigated in detail. There are 290 mud pits, with houses destroyed 1000, more than 200 households relocated, 6,000 mu of cultivated land destroyed, roads, bridges and railways damaged in many places, more than 300 people were killed or injured, and the direct economic loss was over 100 million yuan.

(3) Karst floods: According to 1989 statistics of karst floods in the whole province, there are 44 places with an area exceeding 500 mu, with a total submerged area exceeding 70,000 mu. 1994 552 places in western Guizhou, with thousands of acres of flooded area.

(4) Landslides: 1989, there were 285 landslides in the whole province, and 1994, there were 2036 landslides in western Guizhou, which destroyed more than 1 10,000 houses and occupied about150,000 mu of land.

(5) Other geological disasters have a certain impact on agricultural production, and the degree of harm is relatively light.

3.3 Geological hazard zoning

(1) According to the geological background, topography, hydrology, climate and disaster distribution and development intensity, the geological disasters in the whole province are divided into 6 regions, 1 1 subregion (omitted).

(2) According to the frequency of geological disasters, it is divided into: I Bijie, Liupanshui and Panxian are frequent areas; Ⅱ Anshun, Guiyang and Duyun are prone areas; ⅲ The eastern, northern and southwestern parts of Guizhou are weak areas.

4 the role of geological resources and environment in agricultural production

(1) Rock (including the youngest geological body-soil) is the main part of agricultural geological resources.

(2) Crops are controlled by geological environment and have the regularity of patch distribution.

(3) The core role of mineral elements in crops.

(4) Potential geological resources are an important factor of agricultural sustainable development.

(5) Mineral elements are the starting point of the combination of geology and agriculture.

(9) Establish a species value structure of "people have nothing but me, and people have my superiority" to serve the adjustment of agricultural industrial structure;

(10) Establish ecological sightseeing agriculture to add agricultural scenery to tourism.

5.2 Agricultural production mode of agricultural ecological geology

Excellent variety+excellent geological and ecological environment+ecological agricultural environment+comprehensive balance effect of mineral elements+scientific breeding technology = high-quality agricultural products.

6. The use of geological resources and environment to develop agricultural economy has begun to take shape.

6. 1 economic benefit of flue-cured tobacco planting experiment in geological environment of southern Guizhou

From 1989 to 199 1, after three years of planting experiments in southern Guizhou geological environment, the effect of increasing production and income has been achieved (Table 2), but it has not been popularized.

Table 2 Statistical Table of Flue-cured Tobacco Planting Experiment Effect in Geological Environment of Southern Guizhou

sequential

6.2 Economic benefits of high-quality selenium-enriched rice

Guizhou is located in the selenium-rich geological environment of China, and the main selenium-rich strata are Cambrian, Carboniferous and Permian. At present, high-quality selenium-enriched rice has been successfully developed in Kaiyang, Danzhai, Majiang and Meitan, and Majiang has achieved good economic and social benefits (Table 3).

Table 3 Statistics on Yield of Selenium and Zinc High Quality Rice in Majiang County

6.3 Economic benefits of producing high-quality agricultural products in excellent geological environment

In the process of agricultural census, the relationship between some high-quality agricultural products and geological environment in Guizhou was counted, which confirmed the selectivity, dependence and adaptability of high-quality agricultural products to geological environment, and the prices of high-quality agricultural products produced in the market were generally higher than those of ordinary agricultural products (Table 4).

Table 4 Relationship between Guizhou Characteristic Agricultural Products and Geological Environment

sequential

6.4 Economic benefits of developing new mineral fertilizers

After 10 years of continuous innovative research, a multi-element, low-dose mineral liquid foliar fertilizer was developed from ordinary silicate rocks, named as gold grain foliar fertilizer. After four years of farmland planting experiments, a major breakthrough has been made in developing rock resources and increasing agricultural products, which is an effective method to improve agricultural production level and create new economic growth points.

6.4. 1 plays a key role in increasing rice yield.

Foliar fertilizer with gold particles can promote the development and growth of rice in its infancy, especially the tillering function of rice, which lays the key for increasing rice yield (Table 5).

Table 5 Statistical table of rice tillering with gold leaf fertilizer

6.4.2 Effective Yield-increasing Effect of Rice Planting Experiment

The yield increase rate of rice listed in Table 6 is 5% ~ 32%, which shows the effect of this fertilizer. Due to fertilization, the highest yield of rice reached 10 1 1 kg, an increase of more than 200 kg. Farmers invested more than 400 yuan per mu in 20 yuan, which brought considerable benefits to farmers.

Table 6 Statistical table of rice planting test results over the years

6.4.3 Effective Yield-increasing Effect of Corn Planting Experiment

Corn planting experiments in Kaiyang, Bijie and Guiyang also increased production by about 30%. In 2004, Qiandongnan Agricultural Science Research Institute was invited to experiment, and corn production increased, and the input-output ratio was about 1∶20 (Table 7).

Table 7 Statistical table of corn planting test results over the years

6.4.4 Effective yield increase effect of other agricultural products

At the same time of planting rice and corn, the planting experiments of rape, pepper, kohlrabi, apple, plum, pear, peach and bayberry were carried out, and the yield was generally increased by 10% ~ 28% (Table 8).

Table 8 Statistical table of planting test results of other agricultural products

Note: Fruit is only weighed and compared according to a small number of samples, and the yield per mu is not calculated.

Although the above results are typical, the probability of repetition is high, which lays the foundation for popularization and application.

7. Potential value of geological resources and environmental development

The direct development and utilization of the above geological environment and the transformation and utilization of geological resources are still in the research stage, and the work done is only the tip of the iceberg, which has great economic, social and environmental value potential. At present, the prediction can only be made according to the data obtained from the research results, that is to say, it should be based on a reliable scientific basis. The forecast results hope to attract the attention of government departments, and gradually awaken farmers to consciously implement it through popularization, so as to really increase farmers' income from the perspective of planting industry and increase fiscal revenue for agricultural counties after agricultural tax reduction and exemption.

7. 1 development and utilization of geological environment

7. 1. 1 Develop selenium-enriched geological environment and produce high-quality selenium-enriched rice and tea.

Zunyi, Jinsha, Xifeng, Kaiyang, Qing Yu, Shibing, Zhenyuan, Sansui, Majiang, Danzhai, Taijiang, Jiangkou, Tongren, Duyun, Bijie and Liupanshui in the west all belong to the selenium-enriched geological environment. Using the affinity of rice and tea to selenium, selenium is absorbed from rocks and soil to produce selenium-enriched rice and tea. The rice planting area in Guizhou is 6.5438+0.25 million mu, and 2 million mu has been developed, with a yield of 600 kg and 420 kg of rice per mu, and 840 million kg of selenium-enriched rice can be produced, with an output value of 5.04 billion yuan per kg in 6 yuan. Developing selenium-enriched tea in selenium-enriched geological environment can also double the economic income.

7. 1.2 Develop excellent geological environment and produce high-quality agricultural products.

The proportion of rock exposed area in Guizhou is the highest in China. On the basis of dividing the advantages and disadvantages of geological environment, we should use the excellent geological environment to produce high-quality agricultural products, such as grain crops, cash crops, vegetables and fruits, and the quality of the planted products will reach high-quality products. Develop high-quality rice 1 10,000 t and 4,000 yuan /t with an output value of 4 billion yuan, high-quality corn 1 10,000 t and 2,000 yuan /t with an output value of 2 billion yuan, high-quality fruit 1 10,000 t and 3,000 yuan /t with an output value of 300 million yuan and high-quality pepper of 300,000 t and 3,000 yuan/t. The development of 20 agricultural sightseeing spots can create an output value of 1 100 million yuan, the development of famous tea can increase production by 25%, and the output value can reach nearly 1 100 million yuan. Developing high-quality flue-cured tobacco can improve the yield and quality, producing 654.38+million high-grade cigarettes, with an output value of 30 million yuan per 300 yuan, totaling about 6.8 billion yuan.

7.2 Development and Utilization of Rock Resources

7.2. Economic benefit of1gold leaf fertilizer production

The production technology of gold leaf fertilizer is mature. After calculation, the profit of producing 6.5438 million bottles is 2 million yuan.

7.2.2 Social benefits of gold leaf fertilizer used in agricultural production

(1) The economic benefits obtained by farmers reflect the social benefits of gold leaf fertilizer. If the average yield per mu is increased by 20%, based on the current average rice yield of 500kg in Guizhou, the yield will be increased by 100kg, and the income of 200 yuan will be increased. Producing high-quality agricultural products will increase farmers' income and create new growth points for farmers to increase their income.

(2) If the planting area of grain crops in Guizhou is stable at 45 million mu, and rice is planted with 5 million mu of extended Jingu foliar fertilizer, the average yield per mu will increase by/kloc-0.5% in 2002, the yield per mu will increase by 64 kg, the annual output of rice will increase by 3.2 kg, and the output value of 2 yuan per kg will be 640 million yuan, which will bring huge economic and social benefits.

(3) If it is fully popularized within five years, the grain output of Guizhou can be increased to about140,000 t, and the grain output of the provincial party committee and government can reach138,500 t five years in advance. Grain output increased by 2.96 million tons, with an output value of 8.88 billion yuan. Guizhou needs to import about 6.5438 million tons of grain every year, and it can be self-sufficient without importing grain.

(4) Social benefits of increasing production of other agricultural products. Taking pepper and rape as examples, increasing production every year can create hundreds of millions of yuan in income.

(5) After the increase of agricultural products, it has produced great social benefits in the circulation field.

8 conclusion

Historical experience is worth noting. In the 55 years since the founding of the People's Republic of China, there have been several times of inflation, which are basically related to insufficient food supply. The price increase in 2004 is also related to the decline of grain output in recent years. Therefore, the CPC Central Committee and the State Council regard food security as a political issue of social stability, attach great importance to food production, and require scientific and technological departments to play the role of science and technology as the primary productive force, carry out scientific and technological innovation, and improve the level of food production. Through the scientific and technological resources generated by the combination of geology and agriculture, we can develop geological and environmental resources to jointly serve agriculture, thereby increasing farmers' income, ensuring food security and social stability, and realizing the five major goals of Scientific Outlook on Development's unification and development of the national economy.
