摘要:
?为了研究氟磺胺草醚对大豆的药害情况以及不同缓解剂对药害的缓解作用，在大田大豆喷施氟磺胺草醚后，分2个时期分别喷施8种缓解剂，然后在特定时间分别调查大豆的株高、地上鲜重、叶绿素含量、单株荚数和产量。结果表明：高剂量氟磺胺草醚对大豆药害明显，大豆株高、地上鲜重分别降低16.89%、49.39%，叶绿素含量下降43.75%，单株荚数和产量也分别减少30.0%、14.24%。药害前期喷施宝叶、萘乙酸、赤霉酸和磷酸二氢钾或药害后期喷施宝叶、奈安、芸苔素内酯和氨基酸对大豆产量均有较好的缓解效果。综合分析，药害前期喷施萘乙酸、磷酸二氢钾更有利于大豆增产，其产量较未喷施氟磺胺草醚对照分别增加36.22%和29.88%，可用于修复药害对大豆生长发育造成的影响。
Abstract:
?In order to study the phytotoxicity of fomesafen on soybean and the mitigation effects of different antidotes on the phytotoxicity,eight antidotes were sprayed respectively at two periods after spraying fomesafen in soybean field,and then the plant height,above ground fresh weight,chlorophyll content,pods per plant and seed yield were surveyed at certain growth period.Results showed high doses of fomesafen had obvious phytotoxicity on soybean,the plant height,above ground fresh weight,chlorophyll content,pods per plant and seed yield reduced by 16.89%,49.39%,43.75%,30.0% and 14.24%,respectively.Spraying N-P2O5-K2O,1-naphthlcetic acid,gibberellic acid,KH2PO4 at the early stage of phytotoxicity or spraying N-P2O5-K2O,poly glutamic acid enzyme,brassinolide,amino acid at the latter stage of phytotoxicity separately had better mitigation effects on the inhibition of the phytotoxicity of fomesafen on soybean seed yield.Spraying 1-naphthlcetic acid or KH2PO4 at the early stage of phytotoxicity was more advantageous to the growth and development of soybean and their seed yield increased by 36.22% and 29.88% compared to no fomesafen control,respectively,so they could be selected as antidotes for the phytotoxicity of fomesafen.
