2 . Green fertilisers also require fertilization. Requirements: Increase the application of phosphate fertilizer, supplement nitrogen fertilizer, and use small fertilizer for big fertilizer. The special green fertilizer field should be based on phosphate fertilizer. Generally, calcium and magnesium phosphate fertilizer is 15 kg per mu , which can be combined with cover as base fertilizer. If the weather is warmer after the spring of next year, the additional urea is applied for 2.5 kg per mu . The effect of increasing nitrogen and promoting seedling by nitrogen significantly increased the yield of green manure and fresh grass.   　　 3 . Cover management is also one of the main technologies for winter green manure and high yield. The most common practice is: the farmer will cover the straw left after the harvest of late rice evenly in the green fertilizer field; the straw returning to the field can not only maintain the sustainability of the soil fertility, but also protect the green manure, prevent drought and freeze, and spring for the coming year. Green manure and high yield lay the foundation. Note: If the straw is simmered and then covered, the effect is better; if it is covered with fresh straw, it should be even, not too thick, so as not to affect the emergence of green manure. 　　 4 . Check and fill in the gaps, replanting in time, leaving no empty fields. Some winter green fertilization fields, such as due to drought, a seedling emergence is not good, should be replenished in time after the “horse water†is kept in the field; if the seedlings are affected by the accumulation of water in the field, the drainage ditch should be opened. After it has dried down, replant it at the right time. Such as replanting seeds: fresh, drying, waxing, and soaking treatment, can increase the emergence rate. 　　 5 . Weeding and pest control. Green fertile fields, such as weeds, are very unfavorable for the growth of green manure, especially for replanting green fertile fields, which are most likely to breed weeds. The green manure such as Chinese milk vetch is generally dicotyledon. Farmers can use chemical herbicides such as Jinghecao and Gaiqi to spray herbicides; pests and diseases have sclerotinia, powdery mildew, aphids, etc., should pay attention to comprehensive prevention and treatment.  DVD Rack,Display Rack,Speaker Stand TV Stand Fixed Wall Mount Co.,Ltd , http://www.nstvstand.com
How to manage winter green manure
1 . Drainage and drainage work is the first of all winter green manure management. Regardless of whether it is a special green manure or a combination of green manure, it is a dry crop, and there are often more rains in the winter and spring seasons. Therefore, it is necessary to replenish the ring ditch, the central ditch, and the compartment ditch in time to make the ditch. The same, not only can prevent stains and drought; the bad winter is conducive to draining water in the field. Dry winter should be conducive to irrigation.
