摘要:

为了探讨不同的膏桐混交模式对病虫害的防控效果,通过对云南临沧地区膏桐林纯林及4种不同混交方式营造的混交林(膏桐-虾子花-坡柳-澳洲坚果-咖啡-牛肋巴-芒果-羊蹄夹星状混交;膏桐-澳洲坚果带状混交;膏桐-盾叶黄檀带状混交;膏桐-玉米带状混交)的比较研究,对病虫害的组成和结构进行野外系统调查。采用群落特征指数和主成分分析法对不同种混交方式对膏桐林病虫特征及其稳定性进行研究,比较了不同混交方式膏桐林有害生物的发生格局和生物群落的稳定性。结果表明:研究区膏桐混交林共发现47种昆虫,病原种类33种,与单一种植膏桐林相比,混交种植膏桐林昆虫群落和病害病原菌的丰富度指数、多样性指数和均匀度指数均较高,而优势度指数较低。不同混交方式膏桐林中昆虫群落和病害病原菌多样性指数值大小依次为:Ⅰ膏桐-虾子花-坡柳-澳洲坚果-咖啡-牛肋巴-芒果-羊蹄夹星状混交>Ⅱ膏桐-澳洲坚果带状混交>Ⅲ膏桐-盾叶黄檀带状混交>Ⅳ膏桐-玉米带状混交>Ⅴ纯林。Ⅰ系统中昆虫群落和病害病原菌的稳定性较好,为寻求建立持久有效的混交膏桐林有害生物综合防治方法奠定理论基础。

Abstract:

In order to research the effect of different Jatropha curcas mixed mode on the prevention and control of pests and diseases, an investigation was made on the insect and disease community composition and structure in a Jatropha curcas L. plantation with Woodfordia fruticosa-Dodomaea viscose-Macadamia integrifolia-Coffea arabica-Arehromeris lehmahii, Dalhenqia dituaifolia-Mangifera indica-Bauhinia purpurea stars mixture and Jatropha curcas-Macadamia integrifolia belt mixture; Jatropha curcas-Dalhenqia dituaifolia belt mixture; Jatropha curcas-Zea mays belt mixture. The community character index and principal component analysis were used to study the characters and stability of the insect community. The results showed that a total of 47 insect species and 33 diseases were recorded. In mixture pattern of forestry, the abundance, diversity, and evenness index of insect community were higher while the dominance index was lower. Compared with those in monocultured Jatropha curcas L. pure forest, the diversity index of insect and diseases community decreased in the order of Jatropha curcas L. plantation with Woodfordia fruticosa-Dodomaea viscosa-Macadamia integrifolia-Arehromeris lehmahii, Dalhenqia dituaifolia-Mangifera indica-Bauhinia purpurea stars mixture>Jatropha curcas-Macadamia integrifolia belt mixture>Jatropha curcas-Dalhenqia dituaifolia belt mixture>Jatropha curcas-Zea mays belt mixture. Thus, the insect and disease community in Jatropha curcas mix plantation with Woodfordia fruticosa-Dodomaea viscosa-Macadamia integrifolia-Arehromeris lehmahii, Dalhenqia dituaifolia-Mangifera indica-Bauhinia purpurea stars mixture was relatively stable.
