Jinggu County is located in the southwest of Yunnan Province, west of the central part of Pu 'er City. It is a sugarcane production base county and a national sugar base county in Yunnan Province where the "Advanced Agricultural Products Extension Project" is implemented. Sugarcane industry is the traditional pillar industry in Jinggu County, and it is also the second largest biological resource industry in Jinggu County after forestry. The fiscal revenue can be more than RMB150,000 per year, but it is impossible to achieve high yield and high efficiency. The highest total output is 2007/, the income of sugarcane farmers is 84 million yuan, and the fiscal tax is RMB180,000 yuan, which is far from the goal of high yield and high efficiency. On the basis of summarizing the practice of sugarcane production for many years, the main reasons and solutions of low yield of sugarcane in Jinggu were preliminarily explored, which provided guidance for promoting high-yield and efficient production of sugarcane industry in Jinggu.

First, the main reasons for the low yield of sugar cane industry in Jinggu

1 poor infrastructure jinggu sugarcane industry has a wide planting area, which has remained above 654.38+10,000 mu for five consecutive cropping seasons. However, due to the poor infrastructure such as irrigation and drainage ditches in sugarcane planting fields, the irrigation and drainage requirements required for sugarcane planting can not be guaranteed, which makes sugarcane dehydrated in the big growth period and leads to low yield of sugarcane.

2 Sugarcane planting areas are scattered and the management is extensive. Sugarcane planting areas in Jinggu are scattered, with a few hundred acres and a few thousand acres, so it is difficult to unify the technical management of sugarcane areas. In addition, sugarcane farmers do not plant according to the planting technical specifications, and their thoughts of extensive planting and thin harvest are serious, which leads to poor sugarcane yield and reduces the yield per unit area.

3. Insufficient support, improper selection of sugarcane fields and small proportion of sugarcane fields. The sugarcane planting area in Jinggu has remained above 6.5438+10,000 mu for five consecutive cropping seasons, but more than 86% of the sugarcane planting area is ground sugarcane, and the sugarcane planting area is only 654.38+/kloc-0.00 million mu, which is difficult to cross 20,000 mu. In addition, in recent years, the company's support has declined, and the financial investment in sugarcane industrialization projects has decreased, which has led to the inability to effectively maintain and continue the construction of high-yield and efficient sugarcane orchards, resulting in low sugarcane production.

4. Insufficient investment in introduction test and demonstration, and lagging variety renewal. After the reform of Jinggu sugar industry system, the introduction test, demonstration and popularization were separated, and the agricultural science and technology department was responsible for the introduction test and demonstration according to its functions; This company specializes in sales promotion. But in recent years, the agricultural science and technology department has been responsible for the introduction, test and demonstration of excellent varieties. The company thinks that it has no promotion value and is unwilling to invest in experiments, demonstrations and promotion funds, which leads to the failure of timely and effective promotion of "Shuanggao" sugarcane varieties with high yield and high sugar content, resulting in low sugarcane yield.

5 Insufficient investment in scientific and technological training, low conversion rate of science and technology, insufficient financial and company investment in scientific and technological training, making it difficult to carry out effective, comprehensive, comprehensive, novel and practical scientific and technological training in sugarcane planting, and sugarcane farmers can't learn novel and practical sugarcane planting techniques, resulting in average management level of sugarcane farmers and low output per unit area.

6 Natural disasters and pests and rodents damage Jinggu belongs to subtropical monsoon climate, and natural disasters such as strong wind, hail, freezing and flood occur from time to time, which restricts the high yield of sugarcane to some extent; The harm of insects, weeds and rats occurs every year, especially the harm of underground pests, sugarcane aphids and sugarcane borers, which seriously affect the quality and yield of sugarcane and greatly restrict the increase and income of sugarcane in Jinggu.

Second, Jinggu sugarcane production development countermeasures

1 Strengthen infrastructure construction and improve sugarcane production conditions. By reporting the project construction to the superior financial department, the company will increase its capital investment in infrastructure construction such as irrigation and drainage ditches and tractor-ploughed roads in sugarcane areas, improve infrastructure construction, improve sugarcane production conditions and increase output.

2 contiguous planting, standardized management. In the promotion of sugarcane planting, it is emphasized to choose relatively contiguous fields to develop sugarcane planting, which is convenient for mechanized operation and management, and standardized management technical measures are formulated to require sugarcane farmers to standardize planting and management to increase production and efficiency.

3. Increase support and increase sugarcane planting area. According to the actual development of sugar cane production in Jinggu, the company should formulate a long-term support mechanism that is suitable for the development of sugar cane industry in Jinggu, acceptable to sugarcane farmers and easy to operate, so that sugarcane farmers can have a "reassurance", especially to give more support to farmers who grow sugar cane in the field and improve sugarcane farmers.
