2. Less fertilization. Fertilization is the most cost-effective method of fertilization. Generally, 2~3 kg of urea is applied per 667 m2, or 8~10 kg of superphosphate, and about 10 kg of compound fertilizer can also be used. Micro-fertilizer can be used as base fertilizer or seed dressing. When used as a base fertilizer, it is difficult to spread evenly due to the small amount of use, and it can be mixed with fine soil and then applied to the surface, and then ploughed into the soil. When seeding with zinc or manganese fertilizer, 2 to 6 g of zinc sulfate and 0.5 to 1 g of manganese sulfate per kg of seed are planted immediately after seed dressing.
3. Skillfully apply top dressing. There are two types of topdressing: (1) soil topdressing. The time of top dressing is generally in the jointing stage. The amount of topdressing depends on the seedlings. The wheat is divided into many parts. The seedlings are good and the growth is strong. It should be applied late and reduce the application rate. It can be 15~20 kg per 667 m2 of urea after jointing. Ammonium hydrogen is 40~50 kg. Wheat is less tiller, the seedlings are not good, and the growth is weak. It should be applied early and increased. It can be applied with 20~25kg of urea or 50~70kg of ammonium hydroxide per 667 m2 after regreening. However, for soils with poor soil fertility, the amount of nitrogen fertilizer should not be too large. It is appropriate to apply 15~17kg of urea per 667 m2, and the application should not be too late. However, when the base fertilizer is not applied with phosphate fertilizer and potash fertilizer, and the soil supply of phosphorus and potassium is insufficient, the phosphate fertilizer and potash fertilizer should be properly applied. For high-yield fields with insufficient potassium, it is also possible to apply about 150 kg of grass ash before winter. For wheat fields with sufficient fertilizer, avoid excessive application of nitrogen fertilizer, and the time of top dressing should not be late. Otherwise, it will easily lead to late maturity and reduce production. (2) Spraying outside the roots. Due to inconvenient topdressing in the wheat field, the absorption capacity of the root system is decreasing with the advancement of the growth period. Therefore, if the fertilizer must be applied after the late growth of the wheat, foliar spraying can be used, which is also an emergency measure for increasing wheat production. Every year in late May is a dry and hot wind-prone season. Using 0.2% potassium dihydrogen phosphate foliar fertilizer for 1~2 times, with an interval of 5~7 days, it can effectively prevent dry heat and wind damage.
