| 摘 要： | 小麦返青期,在河北省小麦-夏播作物一年两熟地区冬小麦田施用醚苯磺隆,对其除草效果及其在土壤中的残留在不同耕作方式下对后茬作物生长和产量的影响进行了研究。结果表明:10%醚苯磺隆可湿性粉剂对小麦田主要阔叶杂草有较好的防除效果,对小麦产量无影响。10%醚苯磺隆在小麦田的施药剂量为60 g/hm2,对下茬作物玉米、谷子幼苗的生长及产量无影响,对大豆、花生、油菜的药害轻;随用药剂量增加药害加重,480 g/hm2处理对下茬参试作物均有较重的药害,不同作物对醚苯磺隆在土壤中残留量的敏感性有差异,其顺序为:油菜>大豆>花生>谷子>玉米。播种前进行旋耕比免耕对后茬参试作物幼苗生长及大豆和油菜产量影响要轻。

| 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,480 g/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. |
