摘要 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 safety of seven kinds of herbicid es mostly used in corn fields on seedl ings of Nongda 108were deter-mined by water culture method.The re sults indicated that the safeties of seven kinds of herbicides were diffe rent.The length and weight of shoots of Non gda 108were affected greatly by these herbicides.The inhibitory action s of these herbicides on the lengths of corn shoots were decreased in order as f ollows:acetochlor>acetochlor·a-trazine,alachlor·acetochlor·atrazine,fucaojing·acethchlor>alachlor>fucaojing,a trazine.But effects of the herbicides on the length and weight o f roots of Nongda 108were not signifi cant.
