| 中文摘要: |
| 在新疆阿克苏地区, 2014年2015年选择了枣棉、苹果棉间作模式试验点各24个, 2017年2018年选择了核桃棉间作模式试验点21个, 比较研究了3种模式的间作棉田与相应单作棉田中节肢动物群落结构。结果显示, 与枣树、苹果树、核桃树间作棉田节肢动物群落Shannon-Wiener多样性指数、均匀度指数和优势集中度指数与各自对应的单作棉田相比均无显著差异。对于每种模式, 间作和单作棉田害虫亚群落和天敌亚群落结构特征指数也无显著差异。初步结果表明, 南疆3种常见的果棉间作模式对棉田节肢动物群落结构没有明显影响。 |
| 英文摘要: |
| In Aksu, Xinjiang, 24 experimental sites of jujube-cotton and apple-cotton intercropping patterns were selected respectively from 2014 to 2015, while 21 experimental sites of walnut-cotton intercropping patterns were selected from 2017 to 2018, total of which were utilized to compare and investigate the arthropod community structure corresponding to the cotton fields in three different intercropping patterns and their monocropping patterns. The results showed that the Shannon-Wiener diversity index, evenness index and dominant concentration index of arthropod community in cotton fields intercropping with jujube trees, apple trees and walnut trees were not significantly different from those of cotton field in monocropping pattern. Besides, there was no significant difference in the characteristic indexes of pest subcommunity and natural enemy subcommunity between two cropping patterns. All the results indicated that the three common fruit-cotton intercropping patterns in southern Xinjiang had no significant effect on arthropod community structure in cotton fields. |
