摘 要：
防除油菜田杂草药效试验结果表明:施用50%乙.异噁松EC有效成分525~1125 g/hm2后第30、60、90 d对看麦娘、网草和牛繁缕的综合密度防效分别为92.32%~100%、91.07%~99.68%、92.07%~99.83%,第90 d的综合鲜重防效高达93%以上;施用该药剂能显著提高油菜田间的透光率,降低杂草对田间养分和水分的吸收,对油菜的增产率为29.01%~29.48%。

摘 要：
The results of rape field experiment showed that the synthetic control effects of applying 50% Metazachlor·Clomazone EC 525~1125 g(ai)/hm2 against the density of Aolpecurus aequalis,Beckmannia erucaeformis and Malachium aquaticum were 92.32%~100%,91.07%~99.68% and 92.07%~99.83% respectively on the 30th,60th and 90th day after spraying,and its synthetic control effect against the fresh weight of above three weeds reached to over 93% on the 90th day after spraying.The application of 50% Metazachlor·Clomazone EC could significantly improve the light condition in rapeseed field,reduce the absorption of weeds to nutrition and water,and enhance rapeseed yield by 29.01%~29.48%.
