阿克苏地区不同核农间作系统节肢动物时序动态研究

Studies on the Temporal Dynamics of the Arthropod Community in Different Walnut-crop Intercropping Systems at Aksu Area

对新疆阿克苏地区核桃与农作物间作系统节肢动物进行系统调查,摸清主要害虫的发生规律,为南疆地区核桃主要害虫的控制及果园规范化生产提供理论依据。运用群落生态学方法分析核农间作系统节肢动物的时序动态,结果表明,四种类型核桃园中,全年多样性指数与均匀性指数结果期核桃+棉花间作园最大,幼树龄核桃+棉花间作园次之;而优势集中性指数则是结果期核桃+棉花间作园最低。在核桃与农作物间作时,核桃园建议选择间作棉花。

Systematically investigated on the Arthropods in walnut crop intercropping systems at Aksu area of Xinjiang Region, found out the occurrence rules of major insect pests, Provide theo retical basis for the control of main walnut insect pests and orchard standardization production among southern Xinjiang area. Using the method of community ecology after analyzed the temporal dynamics of arthropod in walnut farmers＇ intercropping systems, the result shows that among the four different types of walnut yards, the first is intercropping of annual diversity index and evenness index fruiting walnut＋cotton, the second is young walnut＋cotton. And the lowest advantage of concentration index is intercropping between fruiting walnut and cotton. Considering the intercropping between walnut and crops, recommend to choose walnut and cotton intercropping.
