摘要:

【目的】研究花椒马铃薯间作对花椒园节肢动物群落结构的影响,探讨有利于害虫生态调控的花椒种植方式,为花椒园管理提供科学依据。【方法】采用群落特征指数法、稳定性分析法和灰色关联分析法对花椒马铃薯间作园和花椒纯作园中节肢动物群落特征进行比较分析。【结果】花椒马铃薯间作园节肢动物群落的物种数、物种个体数、多样性指数、均匀性指数、丰富度指数和稳定性指均高于花椒纯作园。花椒马铃薯间作园的节肢动物群落多样性指数与个体数(r =0.603,P<0.05)、丰富度指数(r =0.815,P<0.01)、均匀性指数(r =0.706,P<0.01)具有较高相关性。【结论】花椒马铃薯间作园节肢动物群落较为复杂和稳定,花椒马铃薯间作模式适于在云南昭通地区推广。

【Objective】Effects of Zanthoxylum bungeanum intercropped with potato on arthropod community structure in Zanthoxylum bungeanum garden were studied to investigate the favorable Zanthoxylum bungeanum planting pattern for ecologically regulating insect pest and provide scientific references for managing Zanthoxylum bungeanum garden. 【Method】Arthropod community characteristics of monoculture Zanthoxylum bungeanum garden and Zanthoxylum bungeanum intercropped with potato garden were compared and analyzed using community character index, stability index and grey relational analysis. 【Result】Zanthoxylum bungeanum intercropped with potato garden had a higher species, individual, diversity, evenness, richness and stability index than monoculture Zanthoxylum bungeanum garden. Zanthoxylum bungeanum intercropped with potato garden also showed higher correlation indexes of diversity and individuals (r =0.603,P<0.01), diversity and richness (r =0.815,P<0.01), diversity and evenness(r =0.706,P<0.01). 【Conclusion】Zanthoxylum bungeanum intercropped with potato garden had a more stable and complex arthropod community, therefore this planting pattern should be adopted and extended in Zhaotong of Yunnan.
