龙胜里骆林区土壤微生物学特性研究

我们研究了龙胜县里骆林区不同海拔高度、不同森林类型和不同土层深度土壤微生物学特性,结果表明:1.不同海拔高度土壤微生物的数量及生化活性以低海拔土壤较高。2.不同森林类型土壤微生物及生化活性常绿阔叶林高于针阔混交林,针阔混交林高于针叶林。3.不同土层深度土壤微生物分布以0～20cm土层最多,20～40cm次之,40～80cm最少。各剖层土壤微生物数量随季节变更有明显季节变化。

A Study on the Properties of Soil Microbiology in the Liluo Forest Region of Longshen County

We studied on the properties of soil microorganism in the different altitude, forest types and soil depth in Lilou forest region of Lengshen county. The results indicatde: Both the number of soil microorganism and biochemical activities at the low elevation are higher than at the high elevation, and the evergreen broad-leaved forest are higher than the broad-leaved and coniferous mixed forest, the coniferous plantation are the lowest. The distribution of soil microorganism is most abundances in 0~20cm in depth, the 20~40cm is less, the 40~80cm is the least. The number of soil microorganism in different soil layer changes remarkably with season change.
