摘要
为揭示在杏麦间作模式下不同树龄杏园节肢动物群落的组成结构及多样性时序动态,调查发现在幼龄的杏麦间作园有节肢动物13目61科189种,老龄杏麦间作园有节肢动物13目59科192种,老龄不间作杏园有节肢动物12目46科120种,同翅目昆虫为优势种,是主要的植食性类群,间作小麦的老龄杏园比幼龄杏园聚集着较为丰富的物种。杏园节肢动物群落的物种多样性与杏树的物候期有关,并受间作物和环境条件的影响,用Jaccard相似性系数和系统聚类法分析了各亚系统之间的相关关系,结果表明杏园间作小麦可以增加杏园节肢动物的物种数和提高系统的稳定性。
The series dynamics were systematically studied to reveal the composition structure and species diversity of arthropods community in different aged apricot orchard under apricot-wheat intercropping system.The survey uncovered that 189 species in 61 families from 13 orders were obtained from young apricot orchards intercropped with wheat,and 192 species in 59 families from 13 orders of old apricot orchards intercropped with wheat,and 120 species in 46 families from 12 orders of old apricot orchards intercropped without wheat.Homoptera insects were the dominant herbivorous groups.There are more arthropod species in old apricot orchards than young apricot orchards intercropped with wheat.The result showed that species diversity related to the phenological period of the apricots and were affected by the intercropping plants and environment coditions.The related correlations between different subunit systems were analyzed with Jaccard similarity indexes and cluster methodology.The result showed that apricot orchards intercropped with wheat can increase the arthropod species and improve the stability of the apricot system.
