1, timely nursery supplements, to ensure that the whole seedlings: 5-7 days after transplanting field view, the lack of ponds, damage the timely selection of tender and strong seedlings to add and replace.
2, timely fertilizer: Miao Fei, 10-12 days after transplanting, Mushi urea 5-7 kilograms of water or human urine or biogas slurry pouring; secondary Miao Fei, 25-30 days after transplanting facilities, Mu application of urea 8-10 kg watered or human urine or biogas slurry pouring to raise the seedlings again; bud moss fertilizer, when the seedling height 35-40 cm, when the main stem buds, about 45-50 days after planting, mu 15-18 kg of urea is used to pour water.
Boron fertilizer was sprayed once during the bolting period, budding stage and early flowering stage. Potassium dihydrogen phosphate was sprayed 2-3 times in the later stage to prevent and control aphids. This promoted satiety of rapeseed grains and increased grain weight to increase production.
3, timely topping: When the seedling height 30-35 cm, growth into the main bolting bud budding stage topping to promote branch growth. Early moss and early flowers that appear before spring should be promptly dispelled and should not be topping again after spring.
4, scientific management of water: the cultivation of water in the field is better, before the spring as the flood water irrigation can be 1-2 times. After entering the spring, due to the gradual increase in temperature, evaporation increased, generally 20-25 days irrigation once, put an end to deep irrigation (easy to cause rape lodging) or irrigation horse water, rapid irrigation speed row.
5. Comprehensive pest control:
Aphids: Use 10% imidacloprid 20g, or 4.5% beta-cypermethrin 30ml, or 50% anti-inflavor wettable powder 10-18g, or 2.5% Kung Fu EC 10-20ml water spray control.
Cabbage caterpillar: Use 4.5% cypermethrin 20-30ml (or 2.5% dichlormia 20ml) + imidacloprid 20g water 30kg sunny spray control.
Sclerotinia: 50% carbendazim 800 times, 70% thiophanate-methyl 1000 times, and 30% sclerotinium wettable powder 1000-3000 times spray are used in the early flowering period of rapeseed. They are controlled once every 7 days. Prevention 2-3 times.
