摘要
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，A3、A4、B1、B5、B6灭除率分别为90．2％、90．2％、923％、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。灭死狼毒第2年返青率为零，且根部腐烂坏死，达到整株灭除。
Experiment with 5 kinds of herbicides and 20 treatments were applied to controlStellera chamaejasme in June 1997. The results showed that the control efficiency of A3,A4,B1, B5 and B6 were 9O. 2%, 90. 2%, 92. 3%, 95. 8% and 81. 0%, respectively and their mainproponent was 2,4-D. The other treatments were not satisfactory. The drown plant couldnot turn green because their root necrosised and decomposed.
