小扁豆田除草剂除草试验

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。

Herbicide Experiment in Lentil Plot

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.
