Calculation of planting benefit of fruit corn
Cost budget:
Planting corn
1. Organic fertilizer: 400 kg? 60 yuan/100 Jin =240 yuan
2. Three elements, compound fertilizer 100 kg? 18 yuan/Jin = 180 yuan
3. Seed cost: 150 yuan
4. Pesticide: 50 yuan/mu.
Four total expenditures: 620 yuan/mu.
the analysis of profit
Plant 3500 plants per mu? For 4,000 plants, the minimum fresh panicle per mu is 3,500, and each panicle is calculated as 400g (8 liang), and 3,500 * 8 = 2,800kg. If the panicle is calculated as 500g (1 kg), it can reach 3,500kg. As long as the scientific planting management reaches 3500 kg per mu.
According to the minimum output of 2000 Jin? 0.9 yuan = 1800 yuan/mu.
One ear of corn: 0.3 kg per plant (about 2-3 bales), calculated as 0.3 kg? 3400 plants = 1020 kg, spikelet? Acquisition unit price 0.8 yuan/Jin =800 yuan.
The minimum product value is 1800 yuan +800 yuan =2600 yuan/mu.
Net profit calculation: the output value per mu is 2600 yuan -620 yuan/mu = 1980 yuan.
Planting skills of fruit corn
1. Selection of planting site: The fertile and loose soil, abundant sunshine and convenient irrigation and drainage are important foundations for high yield.
2. Seedling raising: Transplanting seedlings in nutrient cups (plates) is beneficial to seedling management, ensuring the number of effective plants per mu, ensuring neat growth and saving seeds. Nutrition cup with 8? 8 or 6? 6 yes, nutrition plate 5? 5. There are 48 holes in each tray, and one seed is planted in each hole. Direct seeding is beneficial to seedling emergence. When sowing, the germ of the seed is vertically downward, and the soil is covered with 1.5? 2 cm is enough, the soil should be covered with garbage soil, but large (coarse) clods should not be used to avoid affecting the emergence of seedlings. The nutrient soil is garbage soil or burnt soil, and 2 kg of zinc sulfate and 5 kg of calcium, magnesium and phosphorus are added per mu and mixed evenly. After sowing, keep the water in the nutrition cup to ensure the seeds to absorb water and germinate.
3. Transplanting: directional transplanting, that is, timely transplanting from two leaves to three leaves. When transplanting, ensure that the leaves of each plant have the same orientation, which is conducive to light transmission and ventilation and avoid poor pollination. Sow 2800 plants in spring, 2600 plants in summer and 2800 plants in late autumn.
Fertilization: Base fertilizer is the main fertilizer, accounting for more than 80% of the total fertilizer requirement. Calculated by producing 3000 kilograms of fresh sticks per mu, it needs pure nitrogen 18 kilograms per mu, and calculated by urea content of 46%, it needs 40 kilograms per mu. It needs 8 kilograms of phosphorus per mu. Take 16% calcium superphosphate as an example, it needs 50 kilograms of calcium superphosphate per mu. Potassium per mu 19 kg. Taking 50% potassium sulfate as an example, 40 kilograms of potassium sulfate is needed per mu. Fertilization is best done by pouring. The utilization rate of fertilizer buried in the ground is very low.
Topdressing: according to the plant growth, consider whether topdressing and how much topdressing. Top dressing should be applied to ensure that plants can absorb fertilizer in time. Topdressing is generally carried out during intertillage (5? 6 leaves) or when it is male.
Sixth, pay attention to pest control: during the growing period of corn, pay attention to the prevention and control of bacterial wilt (stem rot) and large and small leaves.
Spot disease is mainly disease prevention, and it should be sprayed 1 before rainy season. 2 times, or when the humidity in the field is high, timely prevention. Corn borer is the main pest, so pay attention to observation when attracting males, and prevent pests in time when they are found. General 1? Just twice.
Seven, timely harvest: after flowering in summer 18? It ripens in 22 days, and is harvested at the milk ripe stage, with the best quality and the highest yield. At this time, the silk turns black and the grain is light golden yellow, which is the best when the color on the control poster is similar.
Nutritional value of fruit corn
(1), which is rich in fat and contains more than 60% linoleic acid, can reduce the deposition of cholesterol in blood vessels, prevent the occurrence of diseases such as hypertension, coronary heart disease and myocardial infarction, and has a positive preventive and therapeutic effect on diabetes.
(2) Is it rich in vitamin E? 2.44mg/kg, it is not only a vitamin, but also can prevent skin pigmentation and wrinkles in advance, and has a good effect of delaying aging.
(3) It contains 0.59% glutamic acid, which can promote the respiration of brain cells, is beneficial to the elimination of ammonia in brain tissue, and has a good effect of bonding the brain and enhancing memory.
(4) High cellulose content can promote intestinal peristalsis, reduce the accumulation of toxic substances in the intestine, and effectively reduce the incidence of constipation, hemorrhoids, colon cancer and rectal cancer; In addition, the cellulose in corn can also prevent many diseases such as hypertension, heart disease, diabetes and obesity.
