| 摘 要： | 两种除草剂中，地乐胺可降低大豆幼苗、根腐病的发生，而乙草胺可国重大豆根腐病的发生，在施工初期（１０天左右）土壤中各和睦具菌被抑制，细菌数量增加；后期地乐胺处理区Ｐｅｎｉｃｉｌｌｉｕｍ和细菌的相对数量有所增加，而乙草胺处理区Ｆｕｓａｒｉｕｍ，Ｒｈｉｚｏｃｔｏｎｉａ数量有所增加，Ｐｅｎｉｃｉｌｌｉｕｍ和细菌的活性被抑制。

| Abstract: | Two herbicides, dibutralin and acetochlor, were studied in this article. Dibutralin could decrease the incidence of soybean root rot, while acetochlor could increase it. During the early period of spraying (about 10 days), some soil fungi (such as Fusarium Rhizoctonia, Pythium, Penicillium) were inhibited, but the number of bacterium increased largely. Later, dibutralin increased the number of Penicillium and bacterium. Meanwhile, acetochlor increased the number of Fusarium and Rhizoctonia, but inhibited Penicillium and bacterium. |
