First, the spring fat Lashi: According to the growth situation and climate characteristics of rape this year, you can control the urea 12.5-15 kg per acre in mid-late January. Nitrogen, phosphorus and potassium fertilizers should be used in conjunction with the application. The amount of fertilizers should be determined by seedlings, and the fields with poor growth should be re-applied and applied early. Increase organic fertilizers, cover with pig manure or soil manure, freeze, keep warm, and increase fertilizer. Spring fat Lashi, both to meet the needs of winter rapeseed growth, but also to promote spring hair, prevent early spring yellow and early convulsions. Second, loose soil roots: The temperature is high, when the soil is suitable, the roots are loosened. This will not only prevent grass from freezing, but also promote the growth of rapeseed roots, which will help stabilize the spring hair. Clean up the ditch system: Waterlogging is the main factor affecting the spring growth of rapeseed. At present, some of the trenches do not support the drainage system, and the drainage is not smooth. The intra-territorial channels are generally shallow and the flooding threat is large. Clearance should be cleared in time to deepen the ditch inside and outside the field, ensure smooth drainage, and promote the long spring rape.
