摘要:
通过对岷江上游连香树、云南松、云杉3种典型森林植被凋落叶及其土壤相同比例混合室内模拟混交实验,研究各处理土壤微生物量C、N的动态变化,以揭示不同凋落叶混合后对土壤微生物活性有无加强作用。结果表明:阔叶树种连香树与针叶树种云南松和云杉均以1∶1混合,对其相应混合土壤的微生物量C、N都有明显的促进作用,这对选择混交树种及配置具有指导意义。西北林学院学报23卷第4期肖波等不同林地凋落叶混合分解对土壤微生物量C、N的影响
Abstract:
Through simulation experiment of leaf litters associating with forest soil of 3 kinds of typical forest(Cercidiphyllum japonicum, Pinus yunnanensis, Picea asperata)in the upper reaches of Minjiang River the regularities of dynamitic changes of the contents of carbon and nitrogen in soil microbiomass(MBC) and (MBC) were studied to reveal the effect of different litters mixed on edaphon activation. The results showed that in the situation of mixed with 1∶1 proportion of broadleaf of C. japonicum litter with conifer of P. yunnanensis and Picea asperata, the same proportion of soil MBC,MBN could be promoted significantly, indicating the importance of selecting mixed plantation forest type and match proportion.
