套作油菜对杏-麦间作果园节肢动物群落影响初探

Preliminary Discussion on Influence of Interplanting Rape on Arthropod Community in Apricot and Wheat Intercropping Orchard

对套种油菜的杏-麦果园和杏-麦间作果园节肢动物群落的初步系统研究表明,新疆南部绿洲荒漠生态区杏-麦间作果园节肢动物共计24种,隶属11目,21科。杏-麦间作果园套作蜜源植物(油菜)能够提高果园生态系统的生物多样性,显著增加天敌果园生态系统的稳定性以及节肢动物群落天敌亚群落。

The preliminary investigation of effect of interplanting rape on aithropod community in apricot and wheat intercropping orchard was carried out. The results showed that 24 species of arthropod were found in apricot and wheat intercropping orchard of oasis desert region in the south of Xinjiang,which were subordinate to 11 orders and21 families. The interplanting nectar source plant（Rape）in apricot and wheat intercropping orchard can increase biologieal diversity in orchard ecosystem and number of natural enemy of injurious insects, thereby the stability of orchard ecosystem can be significantly increased.
