摘要
针对近年来青海省海晏牧场草地狼毒面积成倍增长，对家畜毒害日益严重的问题，于１９９７年６月进行了５种除草剂共２０种处理的化学防除草地狼毒的试验研究。结果表明，５种处理（Ａ３、Ａ４、Ｂ１、Ｂ５、Ｂ６）的灭除率分别为９０．２％、９０．２％、９２．３％、９５．８％、８１．０％，并且５种处理均以２，４－Ｄ成分为主，其他处理效果不明显。因此，２，４－Ｄ可在生产中用于大面积防除狼毒。
xtensive spread of Stellera chamaejasme caused by grassland degeneration which has endangered domestic animals has increased seriously. In order to solve this problem, the experiment of controlling Stellera chamaejasme were conducted with five verieties of herbicides and twenty treatments in Haiyan, June 1997. The results showed that the five treatments (A3、A4、B1、B5、B6) were better than the others, and their controlling efficiency were 90.2%, 90.2%, 92.3%, 95.8% and 81.0% respectively. Combining the results of the five treatments the effective chemicals for Stellera chamaejasme control were mainly 2,4D. The effects of other treatments were not satisfactory.
