田间筛选试验表明:地膜玉米使用除草剂以杜尔与阿胶配合使用(用最各为2.5kg/ha)好于拉索与阿胶配合使用。一般情况下单用杜尔3.5kg/ha以上效果较好,单用拉索则需6kg/ha以上。
Field screening tests showed that the use of herbicides in mulched corn was better than that of donkey-hide gelatin and gelatin (2.5kg / ha respectively). Under normal circumstances alone Duer 3.5kg / ha more effective, single cable is required more than 6kg / ha.
