Abstract:
Field experiment was conducted to study weeds control efficacy of triasulfuron spraying in regreening stage of winter wheat and its residue effect on the growth and yield of after_reap crops(corn,soybean,peanut,millet and rape) under different moulds of tillage in wheat summer seeding crop two_crop per annual region of Hebei.The results showed that 10% triasulfuron WP had better control efficacy on broad_leaves weeds of wheat field and no influence on wheat yield.The application rate of 60 g/ha in wheat field had no influence on the growth of seedling and yield of corn and millet,and had light harm on soybean,peanut and rape.The hazard became heavier along with the increase of application rate,480g/ha treatment heavier harm on all testing after_reap crops.Different crops had different sensibility to triasulfuron residue in the soil,the sensitivity order was rape>soybean>peanut>millet>corn.Comparing with zero_tillage rotary tillage before sowing had less influence on seedling growth of all testing affer_reap crops and yield of soybean and rape.
