摘要
70%苯嘧磺草胺WDG与41%草甘膦AS混用,速效性较好,持效期较长,对未出土的杂草有一定封闭作用;70%苯嘧磺草胺WDG 21～42 a.i.g/hm2+41%草甘膦AS 1 230 a.i.g/hm2在免耕地除草后,对后茬直播油菜有一定影响,应进一步试验验证,但对后茬移栽油菜、直播小麦影响较小,可以示范推广应用。
The quick-acting result of saflufenacil 70% WDG and glyphosate 41% AS against weeds in no-tillage farmland is better and its persistent effect is longer particularly for control of the weeds under ground.Useing of berbicide saflufenacil 70% WDG ＋ glyphosate 41%AS with a dosage of 21~42 a.i.g/hm2＋1 230 a.i.g/hm2 to control weeds in no-tillage farmland has certain influence on following direct-sowing rapeseeds which should be further verified,but has less impact on following transplanting rapeseeds and direct-sowing wheat.So this experience can be confirmed to be used for demonstration and extension.
