化学除草在森林防火路上的应用

在尤溪县国营经营林场埔宁工区进行森林防火路化学除草替代人工除草的试验结果表明,三种处理四个区组16个小区化学除草剂的除草效果均可达70％,其中以4L/hm~2绿草定与20L/hm~2草甘磷混合喷施效果最佳,达80％以上;对禾本科和莎草科杂草,豆科、樟科、漆树科和珙桐科杂灌除草效果最好可达90％以上,而对叶面积较小并带有革质的山茶科杀伤力弱,利于保护木荷防火林带;化学除草可以替代森林防火路人工除草,经济效益高,减少用工84.2％,节约经费34.0％。

Chemical Weeding Applied to the Fire-prevention Pathway in Forests

The experiments made in four different areas in a state-run forest farm to get the forest fire-prevention pathways rid of weeds by Chemical weeding instead of manual work shows that the chemicalherbcide used has a 70% weeding result on an average, which can reduce manpower by 84% and save the cost by 34%, showing fairly good economic benefit.
