Application of atrazine + acetochlor (isomethasamine, metolachlor) + 2,4-D isooctyl ester weeding, the application rate of èŽ æ´¥æ´¥ is less than 1710 grams (active ingredient), and the sputum can be cautious Planting spring soybeans; the annual application rate of èŽ æ´¥æ´¥ is 1710～2400g (active ingredient), after the spring soybeans meet the rainfall and the sun is full after the rain, the phytotoxicity is serious, the yield reduction is obvious, the spring soybean is not recommended, and the silage corn can be planted. Fresh corn, sorghum, hazelnuts, etc.; the annual application rate of the last year is more than 2400 grams (active ingredient), and the rear can only grow silage corn, fresh corn or popcorn.

The corn field is applied with a mixture of flufensulfuron (or chlorsulfuron) + acetochlor, which can be intercropped with soybeans and rotated.
Application of nicosulfuron (nifesulfonate, oxafluridone) + atrazine + safener in the corn field, or reduction of atrazine in soil (soil treatment changed to stem and leaf spray treatment - reduction of 20%) ~50%, adding functional additives - reducing the amount of 20% or more, applying standard nozzles, etc.), after 2 to 3 years, can grow silage corn, fresh corn, potato, spring wheat, spring soybean, peanut, miscellaneous grains Crops such as rapeseed, melons, vegetables, fruit trees or forage.
