Fertilization of autumn-sown crops should increase the amount of organic fertilizer applied, combine organic fertilizers with inorganic fertilizers, and vigorously promote balanced fertilization techniques to improve fertilizer utilization.
Increase the application of organic fertilizer and promote straw cover technology. Long-term adherence to the application of organic fertilizers, in the case of natural disasters such as drought, flood, wind, frost, etc., the role of disaster prevention and stability is significant. The high-yield plot has a farmer's fertilizer of 3,000 kilograms per 667 square meters , and the medium and low-yield farmland is no less than 2,000 kilograms. Grasping the accumulation of farmyard manure in the higher temperature period, using livestock and poultry manure, litter, weeds, straw, sludge and other wastes for high temperature stacking and tanning, rapid maturity. Straw is covered between the rows of summer crops, and it is rotted by high temperature and rainy weather as the base fertilizer for autumn. Actively promote the straw silage ammoniation technology and straw crushing and returning technology.
Promote balanced fertilization techniques. Promote variable fertilization technology represented by BB fertilizer, balanced fertilization, organic and inorganic combination, and application of NPK. Targeted use of micro-fertilizers, promotion of new high-efficiency fertilizers, promotion of deep application of fertilizers, and improved fertilizer utilization.
Promote supplementation technology. Generally, soils lack potassium, and some soils lack trace elements such as boron, zinc, manganese and molybdenum. Potassium and medium and trace elements should be supplemented in a focused, targeted and step-by-step manner to improve crop yield and quality.
Improve fertilization methods and rationally manage fertilizers. The traditional wheat fertilization habit is the basic application of fertilizer. This fertilization method not only causes fertilizer waste, but also causes the seedling period to grow, the earing stage to fall, the spring cold is easy to be frozen, and the later stage is easy to defer, it should be in phosphorus, potassium fertilizer and organic. On the basis of all the base fertilizers, the total amount of nitrogen fertilizer is 60%~70% , and 30%~40% is applied. At the same time, deep application of machinery is used to reduce the loss of nitrogen fertilizer and improve the utilization rate of fertilizer.
