| 摘 要： | 本文研究了不同耕作方式对稻田节肢动物群落在各生育期数量变化的影响。结果表明,有机耕作区、纯化肥区、常规耕作区各种节肢动物所占比例差异较大。有机耕作区害虫的发生量最少,天敌个体总数最多,天敌对害虫控制作用也最强,纯化肥区害虫发生量较多,可天敌明显减少,天敌数量仅为有机耕作区的41．11％;常规耕作区害虫总数最多,天敌个体总数最少,天敌对害虫的控制作用最弱,表明实施有机耕作,有利于增强稻田自然天敌对害虫的控制作用。

| Abstract: | The impacts of different farming way on arthropod community were researched in different growing periods. The result showed that the amount and structure of the arthropod had a considerable difference between organic farming area, pure fertilizer area and normal farming area. The amount of arthropod and natural enemy in organic farming area were the highest in three areas. The number in pure fertilizer area had the highest in pest, while the number of enemy was only 41.11 percent of organic farming area. In the normal farming area, the number of pest was more, but the number of enemy was the lest in three areas. It concluded that carrying out organic farming way was beneficial to natural enemy. |
