How to apply herbicides before soybean seedlings?
How to apply herbicides before soybean seedlings? Please guide the pre-seedling herbicide to choose the pre-bud herbicide, which has a short residual period and is safe for the next crop, so it is the first choice. After sowing, chemical weeding before seedling can not be selected, such as kekuole, fine grass, 2mai 4mer D and so on. Strict standards, scientific mixing of liquid medicine. The formula of chemical weeding before seedling after sowing soybean is: 48% guangmieling EC 70 ml + 59% Acetochlor EC 100 ml + 70% dou sulfuron soluble powder 2 g, 30 kg of water, one mu of land can be sprayed. When preparing mixed pesticides, the pesticide is first added to the appliance according to the standard, then the powder pesticide is diluted into a mother solution with a little water, and then the appliance is added, and finally quantitative water is added. The appliance should not be filled with water first and then the liquid should be added to prevent uneven spraying and poor efficacy due to insufficient dissolution of water and medicine. Spray at the right time to ensure sufficient water. Spray soybeans immediately after sowing to prevent the weather such as drought from affecting the efficacy, but it should not be too late. The correct method is: the plots with good soil moisture are sprayed 3-4 days after sowing, and the plots with poor soil moisture end spraying 4-5 days before emergence. Therefore, in the application of pre-seedling weeding technology, we must pay attention to sufficient water. Take the air spray sprayer pulled by a small four-wheeled agricultural tractor as an example, its unit weight is 175-200 kg, it is equipped with a high-pressure nozzle and the forward speed is in the second gear of the throttle, so that each can of liquid can be sprayed 6-7 mu, ensuring that the amount of water applied per mu is 30-35 kg. At the same time, depending on soil moisture and climatic conditions, you can spray clean water at any time, 20-30kg per mu to improve the efficacy.
