摘要
研究了化学除草剂在杉木幼林抚育中的除草效果。结果表明,草甘膦和百草枯混合施用的除草效果好,优于单独施用,添加洗衣粉可以增强2种除草剂的除草效果。与传统的人工除草相比,杉木幼林采用化学除草可节约用工70%,节约资金53.8%。
Chemical weeding was proved to be effective on tending of Chinese fir young plantation.The weeding effect of mixed application of glyphosate and paraquat was better than that of single application.And the effect was enhanced by adding detergent.Comparing to the traditional manual tending way,the chemical weeding can reduce 70 percent of weeding time and 53.8 percent of weeding cost.
