主要针对南疆阿克苏地区枣树与农作物间作系统节肢动物开展系统的调查,以群落生态学方法研究枣园节肢动物的时序动态。结果表明:枣园与农作物间作系统节肢动物群落均匀度的季节动态与多样性季节动态呈现基本一致的趋势,多样性时高时低,均匀度也有相应的高低变化,在6月份达到最大并保持稳定。3种类型枣园中,多样性指数与均匀性指数均值大小排序是枣+小麦间作>枣+棉花间作>单一枣园,而优势集中性指数反之。3种类型枣园中枣和小麦间作系统多样性指数和均匀性指数均值最大。可见,在枣和小麦间作系统中通过提高管理水平可有效控制害虫的发生。
Aims Arthropods in jujube and crop intercropping system in Aksu area of southern Xinjiang are systematically investigated and the temporal dynamics of arthropods in jujube orchards are studied by community ecology. The results showed that the seasonal dynamics and diversity seasonal dynamics of arthropod communities in jujube or crop intercropping system showed a basically consistent trend. Diversity varied from high to low and even with varying degrees of evenness, which reached the maximum in June and remained stable. Among the three types of jujube orchards, the order of the mean values of diversity index and evenness index was jujube + wheat intercropping> jujube + cotton intercropping> single jujube orchard, while the dominant concentration index was the contrary. The average of diversity index and evenness index of three types of jujube and wheat intercropping system was the highest. Can be seen in jujube and wheat intercropping system by improving the management level can effectively control the occurrence of pests.
