摘要

通过实地调查与试验分析

研究了镜泊湖区杨桦林、蒙古栎林、人工落叶松林和人工红松林的土壤养分状况和微生物特征。结果表明:杨桦林的土壤有机质含量、全氮含量、水解氮含量、全磷含量及速效磷含量均为最大

其土壤细菌数量、放线菌数量和微生物总量也最大;蒙古栎林的土壤有机质含量、全氮含量、水解氮含量、全磷含量、速效磷含量、细菌数量、放线菌数量、真菌数量和微生物总量均比杨桦林小

比人工落叶松林和人工红松林大;人工落叶松林和人工红松林

除真菌数量处于最高水平外

其土壤的养分状况、细菌数量、放线菌数量和微生物总量均为最小。杨桦林、蒙古栎林、人工落叶松林和人工红松林的有机质含量比例为633∶299∶294∶100

全氮含量比例为1013∶539∶331∶100

水解氮含量比例为868∶418∶310∶100

全磷含量比例为411∶279∶127∶100

速效磷含量比例为523∶220∶271∶100

微生物总量比例为180∶130∶103∶100。
