采用玉米幼苗水培法,测定了7种玉米田常用除草剂对农大108玉米幼苗的安全性差异。结果表明,不同药剂对玉米的安全性不同。农大108玉米芽长和芽重受药剂的影响较大,7种药剂按玉米芽长受抑制程度由高到低依次为:乙草胺>乙·莠、甲草·乙·莠、氟净·乙>甲草胺>氟草净、莠去津。但药剂处理对农大108玉米根长和根重的影响不明显。
The maize seedling hydroponics was used to determine the safety differences of seven kinds of commonly used herbicides on Nongda 108 maize seedlings. The results show that different agents have different safety to corn. Nongda 108 maize buds and buds heavier by the pharmaceutical influence, 7 kinds of agents according to the length of corn bud inhibited by descending order: acetochlor> B, A, B, B, B> alachlor> fluorine grass net, atrazine. However, the effect of pesticide treatment on root length and root weight of 108 maize tubers was not obvious.
