2018-08-10 22:02:19
It refers to the rational supply and adjustment of various nutrients necessary for crops to meet the needs of crop growth, thereby achieving the purpose of increasing yield and improving the quality of agricultural products, reducing fertilizer waste and preventing environmental pollution. Balanced supporting fertilization technology based on soil test results, crop fertilizer requirements, cultivated land fertility and various fertilizer benefits, reasonably determine the fertilization amount of various fertilizers, and process into special fertilizers for various crops, and promote advanced fertilization methods and Technology, to achieve balanced fertilization, lack of supplements, to balance soil nutrient status, improve soil conditions, meet crop demand, and ensure the realization of high-quality, high-efficiency agricultural production goals. Its main content is:
(1) Testing of soil and fertilizer: testing the soil and fertilizer used in the project area, understanding the soil and crop nutrient status, determining the quantity and proportion of various fertilizers and formulas, and providing a basis for scientific fertilization.
(2) Fertilizer test and fertilization recommendation: On the basis of making full use of the existing technical achievements, carry out fertilizer test and demonstration, and carry out data analysis and summary to establish scientific fertilization models of various crops in various soil areas, and obtain various elements. Optimize the amount of economic fertilization, and explore the scientific fertilization methods, periods and times of various regions and various crops to establish a systematic and scientific fertilizer database and expert consultation system to achieve computerization, networking, rapidization and expert consultation. .
(3) Preparation of special fertilizer: According to the high-efficiency formula of each crop developed by research and development, the special fertilizer with high specificity and high technical content is processed, which is directly supplied to the farmers, and integrates technology and materials into one. , production, fertilizer, technical guidance "one-stop service.
(4) Combined with the promotion of advanced supporting fertilization methods, such as the combination of chemical fertilizer deep application technology, micro-element fertilizer application, organic fertilizer and inorganic fertilizer application and fertilization period methods.
