| 中文摘要: |
| 2011年9月与2012年9月，采用改良干漏斗方法，对吉林黑土区不同玉米秸秆还田量（0 kg/hm2、3 750 kg/hm2、7 500 kg/hm2、11 250 kg/hm2、15 000 kg/hm2）小区农田中小型土壤节肢动物群落进行调查。研究时段，共获得中小型土壤节肢动物7 238只，隶属3纲4目3亚目11科，其中2011年2 795只，隶属3纲4目3亚目6科，2012年4 443只，隶属3纲4目3亚目8科。调查数据显示，土壤中小型节肢动物个体总数、类群总数和多样性指数随秸秆还田量增加而呈递增趋势。最小显著差异检验（LSD）结果显示，年际间土壤中小型节肢动物的个体数、类群数、多样性指数和生物量差异性均显著（P<0.001），土壤中小型节肢动物个体数明显受秸秆还田量的影响（P<0.01）。冗余分析(RDA)显示，秸秆还田过程中，土壤温度、湿度、土壤pH、土壤全氮对土壤动物优势类群影响显著，且土壤湿度对土壤中小型节肢动物的影响最大。 |

| A study of community of cropland soil meso- and microarthropods in different amount of maize straw returning（0 kg/hm2, 3 750 kg/hm2, 7 500kg kg/hm2, 11 250 kg/hm2, 15 000 kg/hm2）in the black soil area of Jilin at September of 2011 and 2012. Using modified Tullgren and Baermann’s methods separation the cropland soil meso- and microarthropods were collected from the study area Table 2 shows that a total of 7 238 individuals including species were captured from the soil meso-and micro-arthropods, belonged to 3 classes, 4 orders, 3 suborders and 11 super-families, which of 2 795 individuals collected in 2011, belongedd to 3 classes, 4 orders, 3 suborders and 6 super-families，and 4 443 individuals in 2012, belonged to 3 classes, 4 orders, 3 suborders and 8 super-families. The data show that increased with the amount of maize straw returing in the number of individuals,group and diversity index. The results of least-significant difference (LSD) in table 3 shows showed that the number of individuals, group, diversity index and biomass were significantly different between 2011 and 2012(P<0.001). The number of individuals were significantly effect by the amount of maize straw returing(P<0.01). The redundancy analysis(RDA) in figure 2 shown that the significant effect on soil dominant groups was soil moisure, soil temperture,pH and soil total nitrogen during maize straw returing, of which the effect of soil moisture was the biggest. |
