Rape winter cultivating soil to promote roots and protect seedlings

The advantages of winter soil. The cultivation of alfalfa roots is an important measure for the management of rapeseed in winter, and it is also a measure to increase the yield of root-protecting seedlings. Its main role has five aspects:

1. It can thicken the topsoil of the field, thereby expanding the range of activities of the roots of rapeseed, promoting the development of roots and increasing the area for absorbing nutrients.

2. It can suppress the residual branches, fallen leaves, weeds and germs, which can enhance soil fertility and reduce pests and diseases.

3. It can increase the temperature and protect the fertilizer, especially the roots after fertilization, which can increase the fertility of the soil and increase the temperature of the topsoil, which is beneficial to antifreeze and root preservation.

4. Can reduce the disease. Because the field humidity is reduced, the root system is deep and the spread of diseases such as sclerotinia, downy mildew and white rust is inhibited.

5. Can prevent lodging. The soil thickens the root soil layer, which improves the plant's supporting ability and prevents lodging.

The method of winter soil. The work of cultivating the roots should be carried out in the winter, and the time should not be too late. The soil can be carried out many times. In terms of technology, we should focus on “combining with fertilization”. After the organic fertilizer is applied to the side of the rapeseed line, the soil is rooted and covered with soil to prevent fertilizer loss. Conducive to the decomposition of organic fertilizers. The bauxite should not be too thick, especially not to make the vegetable seedlings too deep, otherwise it will affect the light and axillary buds at the base of the seedlings, causing the plant to open. In addition, it should be combined with the cultivating loose soil. In the early winter, the rapeseed will be ploughed and the soil will be shallowly cut, and the shallow soil will be combined.
