摘  要：
为了解秸秆还田对黑土区农田中小型土壤动物群落的影响,于2016年6—9月在内蒙古兴安盟扎赉特旗调查了玉米秸秆按产量还田0(CK)、4500(JG1)、9000(JG2)、13500(JG3)和18000 kg·hm~(-2)(JG4)5个水平对农田中小型土壤动物群落影响。结果表明:从试验样地共捕获中小型土壤动物3350657只,隶属于53个类群;秸秆还田显著提高中小型土壤动物密度(F=12.040,P<0.05),秸秆还田提高了中小型土壤动物的类群数,但未达到显著水平(P>0.05);JG4处理下中小型土壤动物密度最高(933030只·m~(-2)),类群数最多(34);月份对中小型土壤动物群落影响明显,密度和类群数均在7月最多;JG4处理下中小型土壤动物丰富度指数和优势度指数最高,分别为0.98和0.34;CK处理下中小型土壤动物多样性指数和均匀度指数最高,分别为1.72和1.73。相关分析表明:中小型土壤动物密度和优势度指数与土壤含水量呈显著正相关(P<0.05),而与土壤容重呈显著负相关(P<0.05);中小型土壤动物密度与土壤温度呈显著正相关(P<0.05);中小型土壤动物类群数和丰富度指数与土壤有机质呈极显著正相关(P<0.01);中小型土壤动物群落多样性指数与土壤pH之间的相关性不显著(P>0.05)。

摘  要：
In order to understand the effect of straw returning on cropland soil mesofauna community in the black soil,an experiment with five different amounts of maize straw returning,e. g.,0( CK),4500( JG1),9000( JG2),13500( JG3),and 18000 kg·hm-2( JG4),was carried out in Zhalaid Banner of Inner Mongolia from June to September in 2016. The results showed that totaling 3350657 individuals of soil mesofauna were captured and they were classified into 53 taxonomic groups. Straw returning significantly increased soil mesofauna density( F = 12. 040,P<0.05),and taxonomic groups. The soil mesofauna density( 933030 ind·m~(-2)) and taxonomic groups( 34) were the highest in JG4 treatment. The sampling month had a significant influence on soil mesofauna community,with highest density and taxonomic groups of soil mesofauna in July. The richness and dominance indexes were the highest in JG4,with the values of 0. 98 and 0.34,respectively. The diversity and evenness indexes were the highest in CK,with the values of1.72 and 1. 73,respectively. Correlation analysis showed soil mesofauna density and dominance index were correlated positively with soil humidity( P < 0. 05),while negatively with soil bulk density( P<0.05). There was significant positive correction between soil mesofauna density and soil temperature( P<0.05). Soil mesofauna taxonomic group number and richness index were significantly correlated with soil organic matter content( P < 0. 01). Soil mesofauna community had no correlation with soil p H( P>0.05).
