Wheat winter classification fertilizer management

Weak seedlings are weak seedlings that are formed due to lack of fertility and lack of public opinion. They must seize the opportunity for higher temperatures in the winter before they are conducive to taking root and give priority to management. When entering the post-harvest period, watering after top-dressing and timely cultivating tillage have a significant effect on promoting root growth, increasing glutinous rice, and changing from weak to strong. Second, late seeding weak seedlings is mainly due to accumulated temperature is not enough, do not respond to top-dressing watering, so as not to reduce the ground temperature, affect the emergence of seedlings, can be shallow soil loosening, warming and security. Thirdly, the weak seedlings with poor site preparation quality, lack of ground and dust, and lack of sensation can be repressed in winter and shallowly pressed afterwards in order to save the land.

Wang Miao First is the Wang Miao seedling which is formed due to good soil fertility, large amount of base fertilizer, adequate moisture content, early sowing date, etc., and can adopt continuous deep root cutting to control Wang Miao. Generally, it is not suitable for deep cultivating. Phenomenon, can be used stone rolling rolling to control the main stems and big pigs, grow strong control. The second is that the seedlings with too early sowing time and excessive sowing volume should be seeded and thinned before winter. The wheat fields that may be defertilized after thinning seedlings should be topdressed and watered as appropriate to promote their robust growth.
