Rapeseed topped winter fertilizers and increased yields in the coming year

Due to the long growing period of rapeseed, nitrogen fertilizer and potash fertilizer can be used in different times to increase the utilization rate. For this reason, the frequency of fertilization should be appropriately increased. In addition to basal fertilization, overwintering fertilizer, buddy manure and flower fertilization should be applied. For direct seeding and interplanted rapeseed, it is necessary to increase the time of raising seedlings in winter. The fractional application of nitrogen and potassium fertilizers should appropriately reduce the amount of basal fertilizer and increase the application rate during the growth period. Specific fertilization period: For transplanting rapeseed: 60% of the total nitrogen and potassium fertilizers are used as base fertilizer, 20% for wax fertilizer (50 days after transplanting), and 20% for manure (80 days after transplanting); Rape: 40% of the total amount of nitrogen fertilizer is used as base fertilizer, 30% for drawing fertilizer (about 25-30 days after sowing), 15% for wax fertilizer (about 80 days after sowing), and 15% for alfalfa fertilizer (after sowing 110 Days or so), 60% of the total potassium fertilizer is used as base fertilizer, 30% for wax fertilizer (about 80 days after sowing), 10% for alfalfa fertilizer (about 110 days after sowing), and the rest of the fertilizer is used as base fertilizer.
