Many rural families will grow rape. How to manage rape planting?

The first frost solar term has passed, and the real winter has come. At this time, the transplanted rape seedlings have also been put into overwintering management. It is said that the seedling stage of rape is the key period of life, which is related to the high yield of rape, and the plants can reach the standards of rooting, sprouting leaves and thick green leaves. Therefore, after the emergence of rapeseed, the correct field management at seedling stage is the most important thing to cultivate strong seedlings before the arrival of winter! Now I will share with you how to manage rape seedlings in the field!

Transplant strong seedlings. Transplanting rape seedlings is an important measure in production. Transplanting can be arranged at an appropriate time, which can ensure comprehensive seedling conditions, good management and high yield. The transplanting time is generally in the middle of June 5438+10 month. Choose rape seedlings with a seedling age of about 40 days, more than 6 leaves, a height of 20 cm, a thickness of half a cm, and no pests and diseases. Minimize root damage, dig deep into the lower part of leaf base, and do a good job of root water accumulation. The requirements are basically the same as those of pre-seedling treatment. Herbicide is sensitive to beans and peach trees, so we should pay close attention to it when using it.

The principle of fat and water. To cultivate strong seedlings in winter, in addition to transplanting strong seedlings, it is necessary to check the seedlings in time and make up the posts to protect them. Now the temperature drops rapidly. Years ago, the principles of rape fertilization were mainly to eat less and eat more, dilute first and then concentrate, combine water and fertilizer, raise seedlings with nitrogen fertilizer and increase absorption capacity. In addition, wax fertilizer can be applied to protect seedlings in late June of 65438+February, and 20 kg of compound fertilizer and 2000 kg of farmyard manure can be applied per mu. Combined with mixed application of intertillage, winter irrigation can be started when the temperature drops below 5℃, which is more conducive to the overwintering of strong seedlings. If conditions permit, you can also spray boron fertilizer, which is of great help to increase production.
