Rape is a autumn sowing crop and has a certain ability to resist cold. However, cold air invasion, unscientific species selection, late planting period, improper application of fertilization management measures during winter, and other reasons often cause rape damage, resulting in varying degrees of Reduced production or even no harvest, so it is necessary to take timely measures to protect against freezing. Re-applied wax fertilizer farmer said: "Lands per thousand poured better than a pot of wax." Application time of wax fertilizer is appropriate 10 to 15 days before the winter solstice, generally 1200 to 1500 kilograms of pig dung per acre, or soil miscellaneous fertilizer 2500 ~ 3000 kg, can increase the soil temperature 2 °C ~ 3 °C, play the effect of winter spring hair. The cultivating ripping soil and cultivating soil roots can improve soil environment in rapeseed fields, regulate soil moisture, increase ground temperature, and prevent lodging, reducing the harm of grass and sclerotia. The depth of cultivator should be different according to the growth of rapeseed. Generally, it should be shallow and deep, and it should be shallow and shallow for long-term and prosperous, combined with cultivator roots before wintering. Before the application of thin, faecal water for freezing, 600-800 kg of manure water per acre is poured to increase the concentration of soil solution, so that the soil is not easily frozen, thereby reducing the root freezing injury. Fertilizer sprayed with potassium dihydrogen phosphate and vigor, etc. during the overwintering period, sprayed 0.2% borax solution on boron-deficient rapeseed, which is conducive to freezing and seedling protection. Increased cover covering rape seedlings with soil miscellaneous fertilizer, grass ash and crop stalks before winter can maintain relatively stable ground temperature, reduce transpiration of leaves, avoid direct damage of cold air to the leaves, and can also bridge the earth seam to prevent air leakage. Such as covering rice straw, 200-300 kilograms per mu, not only protect the antifreeze, but also increase soil organic matter. The straw that covers the surface of the crop can be naturally implemented in the event of rainfall, and generally does not affect the photosynthesis of rapeseed. After the cold has been remedied after freezing, the seedlings shall be checked in time, and the rapeseed with rooting phenomenon must be crushed in time to cultivate 8 to 10 centimeters in order to prevent the cutting off of roots. Precipitation in the rain and snow as early as possible to prevent waterlogging in the field, prevent waterlogging from hindering the growth of the roots, disperse wood ash during thawing, and timely spray water on the leaves to ease the imbalance of water and prevent water-dead seedlings; timely patrol of quick-release fertilizer after thawing Branches are promoted and fruiting areas are increased; buds with severed main stems and severely frozen leaves are removed in time.
