| 摘 要： | 随着云杉矮槲寄生对三江源地区天然云杉林危害的持续加剧,对其防治的需求愈加迫切。利用不同浓度的40%乙烯利水剂对云杉矮槲寄生进行阶段性喷施防治发现:比例为1∶200的40%乙烯利水剂在云杉矮槲寄生花期、果期防效最佳;利用柴油作为溶剂配制不同浓度的40%乙烯利油剂对矮槲寄生花期、果期进行喷施发现:1∶200的40%乙烯利油剂具有更显著的防效,且未对云杉和树下灌草产生不良药害反应。

| Abstract: | As the harm continuing increasing to natural spruce forest in the Sanjiangyuan Region by dwarf mistletoe（ Arceuthobium sichuanense）,the control become more and more urgent. Using different dilution of 40% ethephon to control dwarf mistletoe by stages,the result showed that the control effect was best with dilution of 1 ∶ 200 in the flowering phase and fruiting phase of dwarf mistletoe.Meanwhile,it is found that dilution of 1 ∶ 200 diesel to 40% ethephon has a significant controlling effect in the flowering phase and fruiting phase of dwarf mistletoe,and it is also has no adverse effect on spruce and shrub grass. |
