| 摘 要： | 采用室内生物活性测定的方法，研究了除草剂解毒剂N-二氯乙酰基-2-甲基-1-氧杂-4-氮杂-螺4,4]壬烷减轻除草剂乙草胺对后茬作物水稻的残留药害。通过对水稻株高和株鲜重等生理指标的测定，研究了该解毒剂对除草剂乙草胺的解毒效果。试验结果表明：在施用不用浓度的乙草胺的土壤中，用浓度为8mg·kg^-1的解毒剂浸种时，对水稻株高、株鲜重等生理指标均达到最佳的解毒效果，可使龙粳14水稻的株高恢复到对照的95.89％、84.07％、66.32％；株鲜重恢复到对照的107.56％、84.18％、67.92％。

| Abstract: | Taking the method of the indoor bioassay to study the herbicide antidote dichloroi-N-acetyl-2-methyl-1-oxa-4-aza-Lo 4.4] nonane to reduce acetochlor on succession crop-rice's residues injury. Studing the effects of the antidote to herbicide acetochlor's detoxification by measuring rice's plant height and plant fresh weight etc.physiologlcal index. The results show that: by using different acetochlor concentration in the soil, the concentration of 8mg/kg antidote soaking that make the rice plant height and plant fresh weight etc. physical index achieve the best which make rice plant height restored to the comparion of 95.89 percent、 84.07 percent,66.32 percent and the plant fresh weight restored to the comparion of 107.56 percent,84.18 percent,67.92 percent. |
