The period from the return of green wheat to the flag picking is the spring growth stage, which lasts for 50 to 60 days, which is a key period for the formation of yield. Therefore, doing a good job of spring management of wheat has a very important role in improving wheat yield, the most important of which is to do a good job in fertilizer and water management.
In the winter wheat regreening period, the weaker seedlings of the middle and lower wheat fields and the high-yield wheat fields with poor soil fertility, especially the de-fertilized weak seedlings without winter fertilizer, should be traced back to the green fertilizer, and whether it should be returned to Qingshui, it should be flexibly controlled according to the lyrics. In winter wheat fields with more precipitation or winter water before winter and winter, if the spring soil is suitable, it can only recover green fertilizer, not returning to Qingshui, and generally topdress in the soil returning stage. If the soil moisture is poor, the recovery of green fertilizer must be combined with the pouring back to Qing Shui. Apply 10 to 15 kilograms of standard nitrogen fertilizer per acre and apply deep ditch. Strong seedlings or Wang Miao in high-yield and high-yield wheat fields should be controlled during the regreening period. For plots that have not been applied with phosphate fertilizer, potassium fertilizer or insufficient application before planting, 30-40 kg of standard phosphate fertilizer and 10-15 kg of potash fertilizer can be applied per mu in early spring.
