上的依据。[方法]将小麦田和油菜田交界处设为0 m,在距0 m处2、4、6、8、16 m(包括0 m)处设立试验小区,记录节肢动物数量,计算主要特征参数。[结果]临近油菜的小麦上蚜虫丰盛度最低,主要天敌丰盛度最高;距离油菜0 m处麦蚜亚群落稳定性较好;距离油菜0 m处捕食性天敌亚群落稳定性最高,16 m处最低;邻作小麦田昆虫群落稳定性高于单作小麦田;油菜小麦邻作可以降低6 m以内蚜虫种群数量,增加6 m内捕食性天敌的数量以及4 m内捕食性天敌的多样性。[结论]油菜与小麦邻作对于麦蚜的防治有一定的作用,但控制范围有限。 |

[Objective] To uncover the change of the insect community in rape wheat adjacent planting and monoculture wheat fields to provide a theoretical practical basis for the wheat production. [Method] The junction of wheat and rape fields was designated as 0 m as the base, and the test regions in 2, 4, 6, 8, 16 m away from the base (including 0 m) were established, in which the quantity of arthropods was recorded, and main characteristic parameters calculated. [Result]The abundance of aphids was the lowest in the wheat fields near rape. However, the abundance of major natural enemies was the highest; in the wheat planted adjacent to rape, the stability of aphids and major natural enemies in the wheat fields were the highest at 0 m distance, but the lowest were at 16 m distance; furthermore, the stability of insect communities in the wheat fields was higher on the wheat planted adjacent to rape than on wheat monoculture; adjacent planting could reduce the quantity of aphids within 6 m, and increase the quantity of predatory natural enemies within 6 m, or increase predatory natural enemy diversity. [Conclusion] Rape wheat adjacent planting mode could control the quantity of aphids, but the control range was limited. |
