Their frequencies are 66.37% and 16.72%, respectively. Liposcelididae, Ceratopogonidae, Chironomidae, Staphylinidae, Nematoda, Enchytraeidae are common species.

弹尾目昆虫对重金属污染的反应，不同的种之间有很大的差别，其中，裸长角属对Cu污染反应不灵敏，陷等属、棘属对Cu污染反应敏感，随着污染程度的加剧，它们的数量明显减少；小等属和长属对Cu、Zn、Cd、Pb等重金属元素的复合污染反应很敏感，而裔符属、球圆属、土属、圆属和鳞长属对重金属复合污染反应很迟钝，在这些重金属复合污染严重的农田中仍能很好地生存繁衍。

In order to get the relationship between mental pollution in soil and vegetables and support green vegetable production, five kinds of common foliage vegetables(Lettuce Plant, Schizonepeta Tenuifolia Briq, Lpomoea aquelica, lettuce, Amaranthus hypochondriacus) were taken as experimental materials to study the correlation between the polluted vegetables and the soil of different concentration of Cd cultivated in greenhouse. The soil pollution threshold values to produce the green vegetables were analyzed.

为探求土壤重金属污染和蔬菜污染的相关性，为绿色蔬菜生产提供技术支持，该研究以郑州市常见的5种叶菜类蔬菜(油麦菜、荆芥、蕹菜、生菜、苋菜)为试验材料，采用温室盆栽土培试验方法研究了土壤不同浓度 Cd污染与蔬菜污染的相关性，并对绿色蔬菜生产要求的土壤污染阈限值进行了分析。

Therefore it's necessary to contol the concentration of TW80 to use it in the remediation of pyrene contaminated soil by AMF and corn integrated systerm.4. The AMF community and the single species derived from rock oil-contaminated soil all can be combined with corn and promote the remidation of pyrene contaminated soil , the original AMF community has obvious advantages and behave best.The residual pyrene concentration of soil in the treatments with the mixed AMF community M4 (Glomus intraradices, Glomus mosseae, Glomus etunicatum and Acaulospora tuberculata) and corn integrated systerm got 0.12mg/kg,0.54mg/kg and 3.92mg/kg respectively in 1mg/kg, 10mg/kg and 50 mg/kg pyrene treatments,decreased 32.6%,58.6% and 42.2% respectively than that of the treatment of M1,decreased 28.1%,59.9% and 36.6% than that of M2(G.intradices), decreased 2.7%,55% and 23.5% than that of M3 (G.intradices + G.mossea).5.Large scale reproduce overall of AMF community which coming from rud oil-contaminated soil in the absence of the original conditions will change the quantiy,composition and structure of the AMF population and may has negative impact on it's function in the remedition of soil pyrene contamination.

因此，在植物与AMF联合修复土壤芘污染中使用TW80应该注意控制TW80的浓度。4、从石油污染土壤中扩繁出的AMF混合菌群及其中的单一菌种与玉米联合均能促进土壤芘污染的修复，原始混合菌群具有明显的种群优势，其与玉米联合修复土壤芘污染的效果最佳。1mg/kg、10mg/kg和50mg/kg芘处理土壤中，玉米接种混合菌种M4(Glomus intraradices， Glomus mosseae， Glomus etunicatum和Arcaulospora tuberculata)处理土壤的芘残留浓度分别为0.12mg/kg，0.54mg/kg和3.92mg/kg，分别比接种单一菌种M1处理降低了32.6%，58.6%和42.2%，比接种单一菌种M2(G.intradices)处理降低了28.1%，59.9%和36.6%，比接种复合菌种M3(G.intradices+G.mossea)处理降低了2.7%，55%和23.5%。5、从石油污染土壤中扩繁出的混合AMF菌群在无原始条件下的整体扩繁会改变菌群的组成及其结构，并会对菌群与玉米联合修复土壤芘污染的功能产生不利影响。
