摘要
作者选择不同经营目的和立地条件的林地在薇甘菊Mikania micrantha H.B.K.不同生长时期开展防治试验。结果表明:在薇甘菊营养期(6—9月),采用人工清理与紫薇清组合,草舒与紫薇清组合及单一使用紫薇清3种防治方式的防治效果均达95%以上;花期使用1 000,1 500,2 000倍紫薇清防治薇甘菊,防治效果分别为98.8%,88.9%,92.9%。建议生产上:以防治薇甘菊为目的在薇甘菊营养期用1 500倍紫薇清防治;以结合除杂灌防治薇甘菊为目的在薇甘菊营养期用100倍草舒+2 000倍紫薇清防治;在林地或有其他经济植物的地方,在薇甘菊花期使用1 500倍紫薇清防治;不方便使用除草剂的地区,采用人工清理即全修防治薇甘菊。
Control experiments were carried out on different growth stages of Mikania micrantha in forests of different management purposes and site conditions. The results showed that the control effect of the combination of manual cleaning and Ziweiqing,the combination of Caoshu and Ziweiqing,and the single use of Ziweiqing were over 95% on vegetative growth stage（ from June to September）. On flowering stage,the control effect of Ziweiqing 1 000,1 500 and 2 000 times were 98. 8%,88. 9% and92. 9% respectively. In conclusion,on vegetative growth stage,Ziweiqing 1 500 times was recommended on controlling Mikania micrantha,the combination of Caoshu 100 times and Ziweiqing 2 000 times could be used on the clearing of miscellaneous shrub. On flowering stage,Ziweiqing 1 500 times was suitable for the woodland or places with other economic plants. The method of manual cleaning was suggested in regions where herbicides were difficult to use.
