摘要
南方冬春季种植的亚麻,其生长期基本上同小麦、油菜相仿,田间主要杂草是 看麦娘、牛繁缕、 草及碎米荠。试验表明:72%都尔乳油用量 130ml/667m2,在亚麻播 后苗前封土处理,其鲜重防效达84.7%; 17.5%快刀乳油、10.8%高效盖草能乳油及5%禾 草杀星乳油用量60ml/667m2在亚麻出苗后20—30天喷雾,其鲜重防效分别为98.1%、87. 1%和92.7%。上述药剂对亚麻安全无药害,一次用药能完全控制亚麻全生育期的杂草危 害。
Alopecurus aequalis Sobol., Stellaria aquatica Scop., Beckmannia syzigachne (Steud). and Cardamine hirsuta L. were dominant in flax field in south. The result indicated that weed control effect on fresh weight reached 84.7% at the rate of 130ml a.i./667m2 with 72% Metolachor before emergence of seedling. Spraying Benazolin-ethyl.quizalofop-P-ethyl i Gallant ?super and quizalofop-P-ethyl 20-30 days after emergence of seedling control effect on fresh weight respectively were 98.1%,87.1% and 92.7% at the rate of 60 ml a.i./667m2. These five herbicide didn't damage seedlings of flax and sprayed once can controlled completely weed injury of total growing period in flax field.
