摘　　要：在筛选适宜的茎叶除草缓解剂处理,以期解决茎叶除草造成大豆叶片损伤继而影响产量问题。以大豆品种“克豆52”为试材,利用松·喹·氟磺胺乳油茎叶除草处理。3种缓解剂GAP、GAL、GAC分别设置3个浓度2个施用时期共18个处理,CKW茎叶除草次日喷清水,CKA仅进行茎叶除草。通过调查、统计、分析大豆叶片药害指数、株高、节数、有效荚数、百粒重,结合经济效益和对杂草影响决选最优处理。结果表明,AC1处理便于农户掌握,产量最高,增产18.48%,综合收益较高,对除草效果影响较小,值得在生产上推广。The aim of this study was to select the suitable treatment of stem and leaf herbicide mitigation agent,in order to solve the problem of soybean leaf damage caused by stem and leaf weeding and then affecting the yield formation.The soybean variety‘Kedou 52’was used as experimental material,the stem and leaf weeding treatments were treated with clomazone,Quizalofop-P and fluorosulfonamide emulsion.The three alleviators GAP,GAL and GAC were treated with 18 treatments at 3 concentrations and 2 application periods,respectively.Water was sprayed on the next day for stem and leaf weeding of CKW,and only stem and leaf weeding of CKA.Through investigation,statistics and analysis of soybean leaf harm index,plant height,node number,effective pod number,100 seed weight,combined with economic benefits,effect on weeds,the optimal treatment was selected.The results showed that AC1 treatment was easy for farmers to grasp,had the highest yield with increase of 18.48%,higher comprehensive income and less impact on weeds,which was worth promoting in production.
