1. Soil treatment before sowing The choice of soil-treated herbicides should consider the safety of soybeans, the length of the effect period, the impact on the crops, and the population of weeds in the field. In general, broad-leaved weeds in soybean fields are mixed with grass weeds, and acetochlor, dur, etc. can be mixed with sike, chlorhexidine, puschte, and broad grass. Generally, saline-alkali land, aeolian sandy land, sandy loam with less than 2% organic matter content, soil drought or leeches are best not treated with soil, and should be treated with post-emergence stems and leaves; for long-term residues such as Puschte and Beansulfuron For herbicide plots, note that the crops are not planted after the sensitive crops.
2, the post-emergence stem and leaf treatment of grassland dominated by grass weeds, you can choose Jinghecao (fine cover grass spirit), take the net, fine and stable kill, efficient grass cover, Weiba, etc.; Weed-based soybean fields can be selected from the group consisting of bentazon, Huwei (flufenazone), kebiramine, kekuole, etc.; soybean fields mixed with broad weeds and broadleaf weeds can choose the above two types of weeding Mix the agents. The selection of pesticides should be carried out in the weeds, the grass weeds in the 2 to 4 leaf stage, and the broadleaf weeds in the 5 to 10 cm height.
