First, return straw
The results of scientific experiments show that improving soil fertility must be based on the premise of increasing organic fertilizers. The application of organic fertilizers can promote the sustained development of fertilizer production efficiency. Adhering to the combination of organic fertilizer and chemical fertilizer is the most fundamental measure to promote a virtuous circle of agricultural production, sustainable use of land resources, and continuous improvement of economic benefits.
Second, the use of soil testing formula fertilization
Soil testing and formula fertilization is a major reform in fertilization technology in China. Soil testing and formula fertilization technology has changed the old habits of past experience in fertilization and applied quantitative scientific fertilization. Because of the soil testing formula, balanced fertilization technology uses soil testing techniques and field tests to test soil nutrient abundance and fertilizer effects, the fertilization technology has obvious scientificity and practicality. It is to increase the utilization rate of chemical fertilizers and reduce the cost of fertilizer used by farmers. The most effective way. Based on the measured soil nutrient conditions, the Weicheng Soil Fertility Station formulated five formulas for wheat and corn. The model household can conduct scientific formula fertilization according to the recommendations of the technical instructor.
Third, the use of slow-release formula fertilizer
The application of the formula fertilizer to the soil after the application of the formula fertilizer relatively increases the stability of the fertilizer and releases the nutrients slowly over a relatively long period of time. This not only ensures the crop's demand for high-yield fertilizer, but also effectively prevents the fertilizer. The loss caused by denitrification, infiltration, and leaching results in the goal of increasing fertilizer utilization.
