摘要
在杨树苗圃，使用草甘膦，百草枯进行化学除草试验的结果表明，除草效果均达90％以上。草甘膦的除草效果优于百草枯，草甘膦持效时间在60d以上，百草枯为30d以上，草甘膦以100g／667m^2加水40kg，百草枯以150ml／667m^2加水40kg使用效果为最佳。并且百草枯与拉索混用．除草效果更好。同人工除草相比，节省费用64～71％。
Carry on chemistry weeding by Glyphosate and Paraqual In poplar nursery, it indicate that weed result more than 90%. Glyphosate weed result superior to Paraqual, Glyphosate hold result time in above 60d, it is above 30 d that Paraqual are withered, Glyphosate adds water 40 kg by each mu 100 g, Paraqual add water 40 kg result of use witheredly as the best by each mu 150 ml. And Paraqual mix with Alachlor, weed result is better. Compared with the situation that weed artificially, saves 64-71% of expenses.
