Timely control. The use of the promotion of Huawang No. 3 during the rejuvenation of the festival forced the rapeseed tops to vigorously recirculate a large amount of nutrients, and the inertia advantage of the rushing tip quickly weakened to the topping situation, increasing field permeability and increasing income. Rational fertilization. In the field of returning to the future, it is necessary to pursue the manure in the field of topdressing. Because of its long fertilizer effect, it is easy to lead to late maturity. Each time with urea or high-efficiency compound fertilizer, timely and combined with the application of photosynthetic nutrient film fertilizer, can help grow rapeseed to absorb light energy, improve fertilizer efficiency, enhance vitality, nourish rain and dew, and thrive. Nutritional delivery. According to the rise of rapeseed in the prosperous period, reasonable fertilization and timely foliar spray fertilizer to meet the needs of rapeseed growth and development, lay the foundation for high yield, generally adopt new high-fat film + "vegetable fruit sturdy", which can make the nutrition transport conduit change Rough, increase the amount of nutrient transport, promote the flowering of rapeseed, and improve the yield and quality of rapeseed. Pest prevention. First of all, it is necessary to clear the ditch, reduce the humidity in the field, and then strengthen the chemical control. The mixture of the fungicide and the appropriate amount of “new high-fat film†spray sprays the middle and lower stalks and the upper branches and leaves of the plant, which can greatly improve the efficacy and achieve the best control effect. .
