摘 要:为明确刺五加根际效应和土壤环境因子对土壤跳虫的影响,于2019年6—8月在中国科学院辽河源农业生态研究与示范基地调查刺五加根际和非根际土壤的跳虫总属数、个体数、功能性状参数以及群落特征参数,同时利用Pearson分析法和冗余分析法研究刺五加根系分泌物和土壤环境因子对跳虫群落结构的影响。结果表明,6—8月在根际土壤中捕获棘?属跳虫176头,所占比例为34.37%,为优势属,捕获钩圆?属、球角?属、长脚?属、德?属跳虫分别为26、37、32和31头,所占比例分别为5.08%、7.23%、6.25%和6.05%,均为常见属;在非根际土壤中,捕获棘?属跳虫91头,所占比例为17.77%,为优势属,捕获钩圆?属、球角?属、长脚?属、德?属跳虫分别为28、33、19和39头,所占比例分别为5.47%、6.45%、3.71%和7.62%,均为常见属;6月,刺五加根际土壤的跳虫总属数、个体数、Pielou均匀度指数分别为3.50、14.92和0.72,非根际土壤的跳虫总属数、个体数、Pielou均匀度指数分别为2.83、8.83和0.87,与根际土壤的差异显著;根际土壤跳虫的体宽、体长、触角与体长的比值、栖息环境功能性状值分别为0.73 mm、4.4 mm、0.19和0.18,显著低于非根际土壤跳虫的0.79 mm、5.58 mm、0.32和0.40;根际土壤p H与土壤跳虫群落的总属数、个体数呈正相关,与Pielou均匀度指数呈负相关,非根际土壤pH与土壤跳虫的个体数呈正相关;德?属、球角?属跳虫与土壤丁香酸含量、水杨酸含量、没食子酸含量呈负相关,长?属跳虫与土壤丁香酸含量、水杨酸含量和没食子酸含量呈正相关,棘?属和钩圆?属跳虫与土壤丁香酸含量呈负相关。表明土壤环境因子和刺五加根际效应对土壤跳虫群落有影响。In order to clarify the influence of rhizosphere effect of Siberian ginseng Acanthopanax senticosus and soil environmental factors on soil Collembola,the total number of genera,number of individuals,functional trait parameters and community characteristic parameters of soil Collembola in the rhizosphere and non-rhizosphere of A.senticosus were investigated in the Liaoheyuan Agricultural Ecological Research and Demonstration Base of Chinese Academy of Sciences in June and August of 2019,and Pearson analytical method and redundancy analysis(RDA)were used to study the effects of root exudates of A.senticosus and soil environmental factors on the community structure of soil Collembola.The results showed that 176 individuals of Protaphorura spp.were captured in the rhizosphere,accounting for 34.37%,which was the dominant genera;26 individuals of Bourletiella spp.,37 individuals of Mitchellania spp.,32 individuals of Entomobrya spp.and 31 individuals of Desoria spp.were captured,accounting for 5.08%,7.23%,6.25%,6.05%,respectively,which were the common genera.A total of91 individuals of Protaphorura spp.were captured in the non-rhizosphere(17.77%),which was the dominant genera;the numbers of Bourletiella spp.,Mitchellania spp.,Entomobrya spp.,Desoria spp.were28,33,19 and 39 individuals,respectively,accounting for 5.47%,6.45%,3.71%,7.62%,which were the common genera.The total number of genera,number of individuals and Pielou evenness index of soil Collembola in the rhizosphere were 3.50,14.92 and 0.72,respectively,in June;the total number of genera,number of individuals,and Pielou evenness index of soil Collembola in the non-rhizosphere were 2.83,8.83,0.87,respectively.There were significant differences between community parameters of soil Collembola in the rhizosphere and the non-rhizosphere.The functional trait values(body width,body length,the radio of tantacle and body length,the habit of rhizosphere soil Collembola)were0.73 mm,4.4 mm,0.19,0.18,respectively,which were significantly lower than 0.79 mm,5.58 mm,0.32,0.4
