摘　　要：2005～2006年进行抗除草剂油菜田施用除草剂莠去津土壤残留对后茬水稻影响的田间小区试验。实验结果表明,40%莠去津悬浮剂900、1200(推荐用量范围)和高剂量1800 g a.i./hm^2在油菜田施用后,推荐剂量范围内对后茬水稻的产量影响不显著,高剂量水稻的产量有明显的影响。这一结果说明莠去津在推荐剂量内于油菜田施用对后茬水稻安全。The field trial on effect of residues of atrizine herbicides in soil on subsequently planted rice were conducted during 2005-2006. The results showed that the effects of atrizinec on rice yield reductions were not significant after the applying of atrizine on rice yield reductions were not significant after the applying of atrizine 900 and 1200 g a. i./hm^2, the rice yield reduction were significant at the higher dosage of atrizine 1800 g a. i./hm^2. This trial show that at the commended dosage atrizine, the subsequently rice could be planted safely.
