| 摘 要： | 以油菜为指示生物,通过水培实验研究了除草剂绿磺隆和甲磺隆对后茬作物的危害。结果显示:除草剂浓度、尿素溶液浓度、缓冲溶液pH值与油菜平均根长之间符合多元线性方程,绿磺隆遵循方程y=6.309 29-0.070 49x1-0.128 58x2-0.333 33x3(R2=0.996 8),甲磺隆遵循方程y=18.372 79-0.220 05x1-0.298 42x2-1.476 67x3(R2=0.995 1);绿磺隆和甲磺隆的浓度,添加尿素溶液的浓度以及缓冲溶液的pH值越大,油菜平均根长越短,对后茬作物的危害越大。

| Abstract: | The toxicity of the clorsufuron and metsufuron methyl to next crops was tested.The results showed that the concentration of herbicides and urea,the pH of buffer and the average length of rape root were conformed to equations,for clorsufuron y=6.309?29-0.070?49?x_1-0.128?579?x_2-(0.333?33)?x_3(R~2=0.996?8),for metsufuron methyl y=18.372?79-0.220?05?x_1-0.298?42?x_2-1.476?67?x_3(R~2=0.995?1)and the greater of the concentration of clorsufuron,metsufuron methyl,urea and the pH,the shorter of the average root length of rape,clorsufuron and metsufuron methyl did greater harm to next crops. |
