摘    要:土壤微生物参与土壤中多种生物化学反应,如矿化-同化、氧化-还原等,是植物营养转化、有机碳代谢及污染物降解的驱动力,在土壤肥力演变,尤其是养分循环中具有重要意义。土壤微生物生物量是指除了植物根系和体积大于5×103μm3的土壤动物以外的土壤中所有活的有机体的量(Paulet a

关 键 词:杉木林  土壤养分含量  土壤微生物数量  土壤微生物生物量

Abstract:It was researched that the numbers and biomass of soil microorganisms in different development stage of Chinese Fir plantation in Shanxia Farm of Sub-tropical Forestry Center, CAF in Fenyi Country, Jiangxi Province. The trend of the numbers and biomass of soil microorganism, the numbers of bacteria and the content of available N, P was decreased from juvenile to medium plantation, and increased from medium to mature plantation. But it was not found the trend from the numbers of fungi and actinomycetes, the content of available K,total N, P, K, in different development stage of Chinese Fir plantation.
Keywords:Chinese Fir plantation  soil nutrient contention  soil microbial numbers  soil microbial biomass
