New ways to manage rape in winter

The weather turns cool and winter is not far away. Farmers should pay attention to the growth of rape, apply fertilizer scientifically and improve the ability of crops to keep out the cold. The alternation of autumn and winter is the key period for rape fertilization. Fertilization before winter or overwintering can promote the slow growth of rape, enhance the cold protection ability of rape, and promote the early development of rape after spring. The so-called "winter fertilizer and spring use" is precisely this truth. Scientific fertilization in autumn and winter can effectively prevent rape from greedy and prosperous after spring, and with the help of winter rain and snow, it can reduce the difficulty of topdressing in spring drought. Improve the utilization rate of fertilizer, and then reduce the cost of agricultural production. Therefore, farmers should apply fertilizer timely according to the growth of crops. Rape fertilization in winter has a lot of attention, generally to ring fertilizer, soil fertilizer, pig manure and other warm farm manure, according to the soil fertility, can be properly added carbon fertilizer, ammonium fertilizer and other fertilizers. After fertilization, weeds should be eradicated as soon as possible and new high-fat film should be sprayed. Cover manure, keep warm and prevent frost, prevent soil from hardening, prevent rape from freezing and fertilizer loss. If rape is planted in the rice field, farmers can use local materials and spray new high-fat film to cover with straw. Generally, the grass is not covered with seedlings and the soil is not exposed. After the rape is harvested, the straw has rotted and can be used as the base fertilizer for the next year.
