1996～ 1999年田间小区试验结果表明 ,大豆田使用不同剂量的金豆 12个月和 2 4个月后 ,小麦、玉米、油莱、甜莱、白菜等作物对土壤中残留的金豆有不同程度的反应。低剂量 (40、6 0ga.i./hm2 )下 ,施药后 12个月对小麦、玉米、油菜、甜菜和白菜等作物的出苗、生长和产量均无明显影响。 80、12 0ga .i./hm2 高剂量施药 12个月后 ,小麦无明显药害症状 ,油菜和甜菜的株高、株鲜重和产量均低于不施药对照区 ;12 0 ga i /hm2 处理区中 ,玉米和白菜有药害表现 ,株高和株鲜重明显低于不施药对照区。施药后 2 4个月 ,上述作物均无明显的药害反应。
The field plots from 1996 to 1999 showed that after a period of 12 months and 24 months in different doses of soybean in soybean field, the contents of wheat, corn, oil Lai, Reaction. At low doses (40, 60ga.i./hm2), no significant effects were observed on the emergence, growth and yield of crops such as wheat, corn, rape, sugar beet and cabbage 12 months after application. After 12 months, the plant height, plant fresh weight and yield of rapeseed and beet were all lower than those of the non-application control area; / hm2 treatment area, corn and cabbage showed phytotoxicity, plant height and plant fresh weight was significantly lower than the non-application control area. 24 months after spraying, the above crops had no obvious phytotoxicity reaction.
