Seeding and seedling: After the whole planting, the soil surface is sprayed with 600-800 times of new high-fat film, which can protect the water-proof evaporation, sun-proof and drought-resistant, heat-preserving and anti-freezing, anti-soil layering, suffocation and isolation of pests and diseases, and increase the emergence rate. Timely transplanting, rational close planting: In order to give full play to the potential of rapeseed production, it is generally carried out by manual drawing, with a row spacing of 30 cm, a plant spacing of 20 cm and a depth of 3 cm. Spraying a new high-fat film in time after transplanting can effectively prevent the ground water from evaporating. The seedlings are not transpiration, isolate pests and diseases, shorten the slow seedling period, quickly adapt to the new environment, and grow healthily. For the rapeseed with long-term fertility, a new high-fat film + foliar fertilizer can be sprayed to inhibit the main shoots from becoming mad, improve the resistance to stress, and reduce the occurrence of freezing damage and pests. Anti-disease and pest control, mixed drug and fertilizer: During the growth of rapeseed, the main pests and diseases are aphids, downy mildew and sclerotinia. For the aphids, the bio-pesticide insects can be used for prevention and control of 1:1300 times, for downy mildew and sclerotinia You can use 12.5% ​​synergistic carbendazim 1:500 times, and add new high-fat film and Zhuangsuiling. This can not only prevent disease and control insects, but also strengthen the physiological functions of rapeseed, improve pollination, insemination, grouting quality and increase 1000-grain weight.
