First, only pay attention to the application of nitrogen fertilizer, and apply NPK fertilizer;
Second, the application of nitrogen fertilizer in some areas is excessive. Nitrogen fertilizer should be applied according to the land output capacity. Generally, 300 kg of wheat per mu is applied with 10 kg of pure nitrogen, 400 kg of wheat is applied with pure nitrogen 12 kg, and 500 kg of wheat is applied with pure nitrogen of 14 kg, 600 kg. Kilogram of wheat with 16 kg of pure nitrogen;
Third, the application of nitrogen fertilizer is unreasonable: all the nitrogen fertilizers should be “one shelledâ€, or the amount of fertilizer in the high-yield field should be too much, the topdressing should be too little, or the nitrogen fertilizer should be applied early in the year, and the high-yield field should adopt the wheat nitrogen fertilizer and the high yield. High-quality cultivation techniques, 50% of nitrogen fertilizer and 50% of topdressing.
The fourth is to promote the combination of potassium fertilizer bottoming and jointing stage, which is beneficial to reduce the loss and improve the utilization rate of potassium fertilizer.
