【摘要】 对小扁豆田杂草进行调查,共有17个科48种杂草。其中禾本科杂草种类少,但数量多,占杂草总量的60%。而阔叶杂草种类多。选用不同类型除草剂、不同施药方式进行除草剂除草试验,结果表明:播前土壤处理,48%氟乐灵乳油除草效果达95.3%;播后苗前施药,48%拉索乳油对禾本科杂草防除效果较好,除草效果达88.7%;45%豆草畏乳油对阔叶杂草防除效果较好,除草效果达86.9%;苗后施药,10%利收乳油对阔叶杂草防除效果较好,除草效果达79.6%。所用各除草剂对小扁豆均表现安全。小扁豆田化学除草应以播前土壤处理或播后苗前施药为主,苗后施药为辅。更多还原

【Abstract】 In the experiment plot,there are 17 and 48 kinds of weeds.The number of Gra mineous weed is more than the number of latifoliate weeds and accounts for 60% of the weeds,but the kinds is adverse.In this experiment,We used different kinds of herbicides and spraying methods.The result shows that the soil processing effect of 48% trifluralin cream is better than other herbicides applied before sowing(95.3% weeds can be killed),and 48% LASSO cream shows better effect to grassy weeds(88.7% weeds can be killed).The killing effect of 45% fomesafen cream is better than the others for latifoliate weeds before applied seedling(86.9% weeds can be killed),and application after seedling 10%flumiclorac-pentyl cream is better(79.6% weeds can be killed).All the herbicides are secure for lentil.According to the result,herbicides should be sprayed before seedling primarily,and after seedling as auxiliary.更多还原
