摘　　要：几种新型除草剂在４年的采伐迹地中使用结果证明，９４０１、金锄、森草净均可有效地灭除３年生以下的平榛和山里红，并可使新萌生的黑桦、春榆等迅速死亡；但对２年生以上的柞萌丛以及鼠李效果不佳．各除草剂对抗药性较强的艾蒿只能杀死幼嫩组织，对木化茎和老叶几乎无效．３种除草剂中，以９４０１杀灌、灭草的效果为最好．Several new herbicides were applied on shrubs and weeds in the site which trees had been clearly cut for four years.The results indicates that Colylus heterophylla and Crataegus pinnatifida under 3yearold were efficiently killed,and clumpy shoots of Betula davurica and Ulmus propinqua could be eradicated in short time.But the clumpy shoots of Quercus mongoilica over 2yearold and Rhamnus spp.were not killed by the herbicides.Artemisia argyi with high antiherbicide were only killed parts of soft and young tissues,were hardly effective to the old leaves and stems.The results showed that 9401 was the most effective herbicide applied on the young plantation.
