| 摘 要： | 为研究施用生物有机肥(EM堆肥,即有效微生物制剂 堆肥)对土壤线虫群落的影响,在中国农业大学曲周试验站进行了11 a施用EM堆肥、传统堆肥、化肥和对照处理的田间试验.结果表明:共鉴定出7目、19科、39属土壤线虫,包括15属食细菌性线虫、4属食真菌性线虫、14属植物寄生性线虫和6属杂食 - 捕食性线虫.植物寄生性线虫是优势营养类群,小杆属(Rhabditis)、螺旋属(Helicotylenchus)和盘旋属(Rotylenchus)是优势线虫属.不同施肥处理土壤线虫总数和食细菌性线虫数量为EM堆肥>传统堆肥>对照>化肥.土壤线虫可用作施肥过程中土壤质量变化的生物学指标. |

| Abstract: | In order to study effects of long-term fertilization on soil nematode community,a long-term field experiment of four fertilization treatments,i.e.EM(effective microorganism) compost,traditional compost,chemical fertilizer and control(no fertilization) was carried out in the Quzhou Experimental Station,China Agricultural University.Results show that 39 genera of nematodes,belonging to 19 family and 7 order,were identified,including 15 genera of bacterivores,4 of fungivores,14 of plant-parasites,and 6 of omnivores-predators.The plant-parasitic nematodes were the dominant trophic group,and Rhabditis,Helicotylenchus and Rotylenchus were the dominant faunas.In terms of total populations of soil nematodes and bacterivorous nematodes,the four treatments followed the order of EM compost>traditional compost>control>chemical fertilizer.So,soil nematodes community could be used as bioindicator of soil ecosystem health. |
