摘要
通过1997~2000年化学除草在尤溪国有林场种子园上的应用效果调查表明,用草甘膦防除幼嫩杂草、白茅、蕨和五节芒效果良好,用克无踪防除杂竹、芒萁效果良好,因此草甘膦与克无踪分别使用效果较好。采用化学除草经济效益显著,1次化除与1次全锄相比,可节省投资210元·hm-2。
The investigation reveals that the effect of controlling young weeds,Imperata cylindrica,,brakes and BMiscanthas floridulus with glyphosate is good.The economic benefit with chemical weeding is significant.Once chemical weeding may save 210 yuan for investment per hm2 as compared with once overall hoeing.
