摘要/Abstract

摘要： 有机磷农药对土壤动物毒性影响的试验结果表明,土壤动物对农药毒性反应敏感,4种有机磷农药处理组的动物种类和数量明显减少.动物种类的减少主要是常见种和稀有种类,动物数量变化则主要是优势类群的数量消长.毒性毒理试验表明,农药对大型土壤动物蚯蚓有明显致死效应,并对蚯蚓、鞘翅目幼虫和等足类鼠妇虫等大型动物的呼吸强度有显著抑制作用,其呼吸代谢强度随着农药处理浓度增加与染毒历时的延长而迅速减弱.

Abstract: The test of organophosphorus pesticide on toxicity of soil animal showed that soil animal is sensitive to organophophorus toxicity,the species and quantities of soil animal treated by four kinds of pesticide are decreased. The species of soil animals was decreased with decreasing common population and rare population,while the amount change of soil animal was associated with the amount change of dominant populations of Acarina and Collembola. Toxicology and toxicity experiment showed that the pesticide has a deadly effect to earthworm,and its toxicity constrained the respiration intensity of big soil animals obviously,which weakened with the increasing pesticide concentration and prolonging poisoning time.

Key words: Soil animal, Organophosphorus pesticide, Respiratiory intensity, Bioindicator, Simulating pollution, N application rate, leaching, accumulation, winter wheat and summer maize rotation system, nitrate nitrogen, long-term experiment
