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8 mg·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%.
採用室內生物活性測定的方法,研究瞭除草劑解毒劑N-二氯乙酰基-2-甲基-1-氧雜-4-氮雜-螺[4.4]壬烷減輕除草劑乙草胺對後茬作物水稻的殘留藥害.通過對水稻株高和株鮮重等生理指標的測定,研究瞭該解毒劑對除草劑乙草胺的解毒效果.試驗結果錶明:在施用不用濃度的乙草胺的土壤中,用濃度為8 mg·kg-1的解毒劑浸種時,對水稻株高、株鮮重等生理指標均達到最佳的解毒效果,可使龍粳14水稻的株高恢複到對照的95.89%、84.07%、66.32%;株鮮重恢複到對照的107.56%、84.18%、67.92%.

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.
