对紫色土长期施肥定位试验地7种不同施肥方式下的土壤动物进行鉴定与分析,研究紫色土土壤动物群落类群及其指示值对施肥的响应.共获得农田土壤动物16 127头,分属于6门,15纲,23目,64类.结果表明,有机物料与化肥NPK配施(OMNPK,RSDNPK)下土壤动物群落多样性和均匀度较高,且显著高于无肥对照小区(CK);通过计算土壤动物类群指示值可知,不同施肥方式对土壤动物类群的指示值有显著影响,OMNPK施肥方式下的大蚓类和RSDNPK施肥方式下的土壤线虫动物门的指示值达到了70%以上,对施肥方式的反映较为敏感,可作为不同施肥方式下土壤质量或肥力变化的特征性指示类群 |

Seven fertilization plots with purple soil were investigated,and soil fauna community groups and the effects of fertilization were studied in the different plots.Totally,16 127 individuals of soil animals,belonging to 64 groups,23 orders and 15 classes in 6 phyla,were obtained.The results showed that the diversities and evenness of soil fauna communities in OMNPK and RSDNPK plots were the highest and significantly higher than those in non-fertilization(CK) plot.Fertilization had significant influence on the IndVals(Indicator values) of soil fauna groups.Only two groups of soil fauna,Megadrileoligochaetes in OMNPK plot and Nematode in RSDNPK plot,with the IndVals >70%,were characteristic and could be used as bio-indicators of fertilization |
