摘 要：
通过优势种阔叶杂草牛繁缕 [Malachiumaquaticum(L .)Fries]对油菜籽产量损失的测定 ,建立了产量损失预测模型 :Y =91.3 0 3 2 - 0 .2 73 0X ;确定了不同除草措施下产量损失经济阈值 ,提出了相应的防除指标 ,即直播油菜田牛繁缕达到 40 ,2 8,3 4株 /m2 时 ,需分别用 3 0 %好实多 (benazolin ethyl)SC、2 1.2 %仙耙(ethametsulfuron +benazolin ethyl+ quizalofop ethyl)SC、17.5 %油菜双克 (ethametsulfuron +benazolin ethyl)EC进行防除

摘 要：
Through the determination of the rapeseed yield loss caused by dominant species broad-leaf weed Malachium aquaticum, a forecast model of the rapeseed yield loss was established, i.e. Y=91.3032-0.2730X;the economic thresholds of the yield loss under different weeding measures were fixed and the corresponding control indexes were also put forward, i.e.when the density of Malachium aquaticum in direct seeding rape field was 40, 28 and 34 plants/m 2, the weed should be carried out with benazolin-ethyl, ethamesulfuron+benazolin-ethyl+quizalofop-ethyl and ethamesulfuron+benazolin-ethyl respectively.
