摘 要:应用"狼毒净"在青海省海南州共和县江西沟乡进行防除狼毒试验研究。结果表明:该药剂对狼毒防效为96.76%,防治效果显著,防除狼毒翌年,对照区与处理区的总产草量和单子叶草产量都达到极显著水平(P<0.01),草地的产草量提高了11.53%,单子叶牧草的产量大幅度提高,提高了16.54%,而双子叶牧草增产效果不明显。防除狼毒后对草地的生物多样性未造成明显的改变;应用"狼毒净"防除狼毒,投入产出比为1∶3.04,经济效益显著。A study on control technigue of Sellera chamaejasme using "Langdujing"was conducted in Jiangcigou village of Gonghe county, Hainan Prefecture, Qinghai Pravincl. The results showed that the control effect of this herbicide on Sellera chamaejasme was 96.76 %. The total forage yield and the monocotyledon forage yield increased by 11.53 % and 16.54% in the treatment area than in the control area in secondl year ( P 〈 0.01 ), respectively , but the increasing effect of dicotyledon yield was inconspicuous. There was not obviously change in the biodiversity of grassland after control Sellera chamaejasme . The input-output ratio of control Sellera chamaejasme using"Langdlujing"was 1:3.04 and there was obvious economic benefit.
