| 摘 要： | 应用化学除草剂对草地狼毒Stellera chamaejasme进行了防除试验,结果表明,在狼毒现蕾期至初花期用43.2%灭狼毒超低容量液剂商品量1.05～2.10 L/hm2原液喷雾,对狼毒防效可达95.29%～99.08%,灭除当年狼毒地上部分干枯死亡,生长点坏死,翌年返青率仅为0.31%,且对大部分优良禾本科和莎草科牧草安全,解决了草地取水不便的难题,尤其适用于干燥草原杀灭狼毒.

| Abstract: | Chemical herbicide Mielangdu was used to control Stellera chamaejasme in alpine grassland. The result indicated that the control effect can reach 95.29%~99.08% at the concentration of 43.2% original herbicide solution during bud to flower stage. The Stellera chamaejasme plant above the ground became wilt and dry, the growing point rotted, with only 0.31% regeneration rate in the following year. It was found that the herbicide was safe to most of Gramineae and Cyperaceae plants. The use of the new herbicide solved the problem of water shortage in grassland, especially fit for dry grassland. |
