How to weed soybeans in summer?

How do summer soybeans weed? After summer soybean sowing, soil and climate conditions are conducive to the germination and growth of weeds, if not removed in time, it is easy to form grass shortage. Weeds should be controlled early according to the occurrence characteristics and herbicide characteristics in summer soybean fields. Soil mixing treatment: after soil preparation, spray topsoil with 48% trifluralin EC 100- 150ml or 33% benthamone EC 200- 150ml per mu, add 30kg water, and then mix with 3- 5cm topsoil, which has good control effect on annual grass weeds. soil treatment: spray 50% acetochlor emulsifiable concentrate 100- 150ml or 48% lasso emulsifiable concentrate 200- 250ml per mu with 30- 40kg of water before seedling. To expand the herbicide spectrum, 50% acetochlor EC 100- 150ml +48% clomazone EC 50ml/mu, or 50% acetochlor EC 100ml +48% clomazone EC 35- 45ml +10% chlorpyrisulfuron 4g + water 40- 50kg spray. Stem and leaf treatment: in the field with many weeds of Gramineae, 40- 70ml of 15% Jingwende emulsifiable concentrate or 40- 60ml of 12.5% gecao Neng emulsifiable concentrate, 60- 100ml of 10% fenoxypyr emulsifiable concentrate and 40- 70ml of 5% fenoxypyr emulsifiable concentrate are selected for spraying in each mu at the 2-4 leaf stage of soybean and the 2-5 leaf stage of weeds. For fields with many broadleaf weeds, spray 40- 50ml of 25% Huwei water solution per mu at 1-3 leaf stage of soybean and 3-4 leaf stage of weeds. When both types of weeds occur heavily, tigmathur can be mixed with fenvalerate, clofop-n, fenoxyp-p, and clofop-p to eliminate both types of weeds. The application should be carried out at noon on a windless sunny day, and the amount of water added per mu should not be less than 40 kg.
