Cold and abnormal cold winter weather after severe winter cold weather caused by rape damage is mainly winter. Freezing damage will lead to a significant reduction in rapeseed production. Its main defense measures are: First, give enough fat. Before the Chinese New Year, 100-150 kilograms of plant ash can be planted, about 2000 kilograms of soil-fertilizer, and 50 or more people's or animal manures can be applied around the roots of the rapeseed or irrigated. Second, the top dressing. For vigorously growing seedlings, 0.2% potassium dihydrogen phosphate can be sprayed; for weaker growing seedlings, 0.5-1% urea solution can be sprayed, or 0.2% potassium dihydrogen phosphate solution can be added for spraying. Add 1500 times 40% omethoate mixed spray and pest control. In the bud stage, spray a chlormeine to cultivate strong seedlings. In addition, spraying 0.2% boron fertilizer solution immediately before and after flowering of rapeseed. Third, cultivator soil. In winter, it is necessary to combine pest control and pest management, cultivating once, pounding fine soil blocks, and cultivating earthworms. Fourth, the drainage ditch.
