Classified fertilization management of wheat in winter

Weak seedling

First, for the weak seedlings formed due to the lack of soil fertility and soil moisture, we should seize the opportunity of higher temperature before winter, which is conducive to the root of tillers, and give priority to management. After entering the tillering stage, topdressing and then watering and timely ploughing and loosening the soil play an obvious role in promoting root tillering and turning from weak to strong.

Second, the main reason for late sowing weak seedlings is not enough accumulated temperature, so we should not rush to topdressing and watering, so as not to reduce the ground temperature and affect the emergence of seedlings, but shallow hoe loose soil, increase temperature and preserve soil moisture.

Third, the poor quality of soil preparation, virtual bumpy, lack of soil moisture late sowing weak seedlings, winter can be suppressed, after shallow hoe, in order to increase soil moisture and preserve soil moisture.

Wang Miao

First, for the excessively prosperous wheat seedlings formed due to good soil fertility, large amount of base fertilizer, sufficient soil moisture and early sowing date, continuous deep hoeing and cutting roots can be adopted to control prosperous seedlings. Generally, it is not suitable for deep ploughing. It is found that there is a phenomenon of prosperous growth, and stone stalks can be used to control the growth of main stems and big tillers.

Second, for the overgrown seedlings formed by early sowing time and excessive sowing quantity, the seedlings should be thinned and compacted as early as possible before winter, and the wheat fields which may lose fertilizer after thinning seedlings should be fertilized and watered as appropriate to promote their healthy growth.
