How to do rape "four evils"
Today is the beginning of the winter season, legislation, and the beginning of construction, indicating that the winter has begun since. The end of winter means that there is a meaning to be collected after the crops are harvested, and China has made Lidong the beginning of winter. Current rapeseed is in a vigorous growth stage before winter, transplanting rapeseed in the 7-10 leaf stage, and live rapeseed in the 4-6 leaf stage. Due to the influence of the continuous rainy weather in the previous period, there are different storage problems in the fields, mainly including waterlogging, pests, weeds, and prosperous growth. Today we come to the system to analyze how to solve the above-mentioned situations. Waterlogging Because of the rainy conditions and the poor groove in the field, most of the fields have stains and flaws with different degrees of storage. They appear as purple leaves, poor root growth, brown growth, and slow growth or stagnation. Field management will continue to do a clean job. On the one hand, heavy-flooded plots are sprayed with high-quality foliar fertilizers (Hailongbao, Midea, American Star, Tsui Lanchun, etc.) and plant growth regulators (Brassica lactoferrin or Bihu), on the other hand. Mushi urea 10 kg to promote the rapid recovery of rapeseed growth. Prosperous Due to the high density of the live rapeseed, and the abundant rainfall and appropriate temperatures, some plots tend to grow or prosper. For high-density plots, seedlings should be promptly sparsed. For prosperous plots, arable roots can be cut off or chemically controlled. Paclobutrazol, uniconazole, or calcium prolongate calcium (salk) can be used to control the temperature and prevent freezing. Pests At present, rape fields and aphids are more common in rapeseed fields, and the levels of beetle and disease are lighter. Taking advantage of the current good eye weather, a pest control of the field occurred, especially the aphids not only affect the normal growth of vegetable oil, but at the same time pass the virus will also lead to the occurrence of virus disease after years. Cabbage caterpillar can choose sword or 9080 or blessing (control locusts when available) to control, aphids can be controlled by imidacloprid (imiram) or pymetrozine (grains, peaks, double electricity). Grass damage Grass weeds can be controlled with high-efficiency flupirtine (Habile) or clethodim. Broad-leaved weeds can be controlled by grass herbicide or clopyralid or its compound. It is worth noting that clethodim can not be applied after flower bud differentiation, and clopyralid is best used if it is followed by broadleaf crops. Use or not, after the grass leaves have been used for 5 leaf periods, otherwise phytotoxicity will occur.
