摘  要：
大狼毒(Euphorbia jolkinii)是云南亚高山草地常见的毒害草,易在地段性区域形成单优群落,对草地畜牧业造成不良影响。为有效防治草地大狼毒,在香格里拉坝区草地开展了除草剂筛选试验。试验设二甲四氯、草甘膦、盖灌能3个除草剂处理,选择大狼毒分布较为均匀的草地划分试验小区,将除草剂原液稀释成50倍液对草地进行喷雾处理。各处理设3次重复,随机区组设计。在喷药当年和次年,对各处理的大狼毒植株和根系死亡率、草地主要植物表观特征及存活状况进行调查。结果表明:在3种除草剂处理中,草甘膦对大狼毒的防除率达到100%,极显著高于二甲四氯、盖灌能(P<0.01);在1 mL/m~2用量时,草甘膦对禾本科等可食牧草的影响不大。试验结果综合比较表明,草甘膦对大狼毒的防除效果较好,适宜用于云南亚高山草地对大狼毒的化学防治。

摘  要：
Euphorbia jolkinii is a main poisonous grass of subalpine meadow in Yunnan. It is easy to form monodominant community in local area,which cause bad effects on the grassland animal husbandry. For effective prevention and control of E.jolkinii,a herbicide screening test in flat area of Shangri-la were carried out. Three herbicides(MCPA,glyphosate and Garlon)were chosen to treat E.jolkinii distribution grassland. The herbicides were diluted by 50 times before spraying on the grass. Each treatment with three repetitions. In the same year and the following year after spraying,a survey about the apparent characteristics and survival status of E.jolkinii,root mortality and main plant grass in each treatment were conducted. The results showed that the control rate of glyphosate to E. jolkinii reached 100%,which was significantly higher than those of MCPA and Garlon(P<0.01);and the glyphosate dosage at the concentration of 1 mL/m~2 had little influence on edible gramineous forage. It was concluded that the glyphosate was more suitable for E. jolkinii prevention in Yunnan subalpine meadow.
