摘　　要：试验探讨了在幼林抚育中使用森草净的适宜技术,开展了森草净不同剂量、喷施时间以及单独使用或与其他除草剂配比使用的控草效果。结果表明:不炼山造林的幼林在春季杂草萌芽前罩住幼树,进行带面喷施有效成份20～60ml/667m2的森草净,可有效地控制幼林地杂草。杂草萌芽后用一定剂量的森草净与草甘膦、森泰混合使用,结合劈草抚育,效果更佳。这种"不炼山耙带造林、幼林化学控草抚育"的新模式,既实现了幼林少耕,又极大地提高了林业的经济效益和生态效益。The weeding effacts of suifometuron-methyl in young stand tending were tested among different spraying dosages,application time and mixed spraying with other herbicides.The results showed that applying suifometuron-methyl at 20～60ml/667m2 before weed sprouting in Spring was effecient to conrol weeds in young stands originated from non-burning-slash afforestration.Also it was found to control weed more efficiently by mannual weeding in addition to applying mixed herbicide of suifometuron-methyl,glyphosate and sen tai after weed sprouting.The new weed control mode,which intergrate afforestration without burning slash and chemical weed control in tending,could not only decrease the labour intensity of tending,but also increase the economic and ecologic benefits of forest management.
