摘要:
[目的] 为了解成都人民公园桑寄生发生情况,并提供相应的防治措施。[方法] 采用路线调查法,调查了成都人民公园受桑寄生侵害的树种及侵害程度,并分析了桑寄生发生的主要影响因素。[结果] 成都人民公园桑寄生发生较为严重。桑寄生对寄主植物具有选择性,柳树(Salix babylonica)、枫杨(Pterocarya stenoptera)、悬铃木(Platanus acerifolia)等中大型乔木寄生率较高,寄生位置通常在乔木的1/2处或更高,被寄生枝干呈明显衰退趋势。距离水源越近、荫蔽度越高、鸟类活动越频繁,寄生率则越高。[结论] 针对成都人民公园桑寄生危害,建议采用人工砍修法或者进行化学防除,可有效防治桑寄生。
Abstract:
[Purpose] To understand the occurrence of Taxillus sutchuenensis in Chengdu People’s Park and provide corresponding prevention and control measures. [Method] The host tree species and the extent of T.sutchuenensis attack in Chengdu People’s Park were investigated by the route survey method. The main influencing factors of T.sutchuenensis occurrence were analyzed. [Result] The occurrence of T.sutchuenensis in Chengdu People’s Park was more serious. The pest was selective to its hosts, and large- and medium-sized trees such as Salix babylonica, Pterocarya stenoptera, Platanus acerifolia were commonly parasitized with a high parasitism rate. T.sutchuenensis was usually found at 1/2 or higher sites of the trees, and the parasitic branches showed a clear decline trend. The closer to the water source, the larger the shade, the more frequent the bird activities, and the higher the parasitic rate. [Conclusion] In view of T.sutchuenensis parasitic hazards in Chengdu People’s Park, it is suggested that artificial pruning or chemical control be used to effectively prevent and control the T.sutchuenensis parasite in Chengdu People’s Park.
