通过试验研究了河南封丘潮土长期施肥处理下土壤跳虫的群落结构及其多样性，试验包括氮磷钾(NPK)、氮磷(NP)、氮钾(NK)、磷钾(PK)、有机肥(OM)、1∶1化学氮肥与有机氮(MNPK)和不施肥(CK)7个处理。结果表明，7种施肥试验处理下，平均土壤跳虫密度为30 000头 m-2，施用有机肥显著增加了土壤跳虫数量，而磷肥可能是该地区跳虫数量增长的一个限制因素。OM和MNPK处理下土壤跳虫多样性显著高于其他处理，OM和NPK处理具有最高的相似性，其次是MNPK和OM处理之间，而CK处理与其他处理相似性指数较小。不同施肥处理下表现了土壤跳虫类群对环境的选择性，多数跳虫与OM处理成正相关关系，而MNPK处理促进了Isotoma和Xenylla属在数量上的增长，PK处理与Hypogastrura和Sminthurinus属有一定的正相关关系。施肥处理也引起了土壤跳虫的垂直分布差异， MNPK、NPK和OM处理下土壤跳虫趋于表层 (0~10cm) 分布，而NK和CK处理下趋于下层 (10~20cm) 分布。土壤跳虫的量化指标（如个体数、类群数和多样性）对施肥处理表现敏感，可作为土壤质量评价的指标之一。
A long-term fertilization experiment was conducted to study community structure and diversity of soil collembola in fluvo-aquic soil in North China.The experiment was designed to have 7 treatments, i.e.combined application of N, P and K (NPK), combined application of N and K fertilizer (NK), combined application of N and P (NP), combined application of P and K (PK), application of organic manure (OM), combined application of organic manure and NPK (organic nitrogen∶fertilizer nitrogen=1∶1) (MNPK) and no-fertilizer treatment (CK).Results showed that the average collembola density of the seven treatments was 30 000 m-2, and application of organic manure significantly increased the size of the soil collembola community, while soil phosphorus content is probably one of the limiting factors for abundance of soil collembola in this region.Soil collembola diversity was higher in Treatments OM and MNPK; and the highest similarity index was observed between Treatments OM and NPK, the runner-up between Treatments NPK and MNPK,and the lowest between CK and any other treatments. The experiment demonstrated high preference of collembola for soil environment. Most genera of collembola were positively related with OM application. Positive response was observed of Isotoma and Xenylla in Treatment MNPK, and somewhat of Hypogastrura and Sminthurinus in Treatment PK. Fertilization also affected vertical distribution of soil collembolan.In Treatments MNPK, NPK and OM they tended to reside in 0-10 cm soil layers , while in Treatment NK and CK they did in 10-20 cm soil layers.The quantitative indices of soil collembolan (such as number of individuals, number of orders and diversity), being very sensitive to fertilization, can be cited as an important indicator in soil quality evaluation.
