摘要：通过对江西省分宜县中国林科院亚热带林业实验中心的山下、上村２个林场的一代和二代杉木人工林根际及非根际土壤微生物数量及种类的研究发现，二代杉木人工林土壤放线菌数量、类群以及芽孢杆菌属、固氮菌属、纤维单胞杆菌在细菌中所占比例均明显比一代杉木林的少；但真菌数量以及土壤杆菌、微球菌属、色杆菌属在细菌中所占比例、青霉菌在真菌中所占比例均明显比一代杉木人工林的高。一代和二代杉木人工林根际土壤的放线菌数量均比非根际土壤的少，细菌数量却比非根际土壤的多。
This article dealt with the amounts and species of rhizosphere and non rhizosphere micoorganism of the 1st and 2nd generation of Chinese fir in Shanxia and Shangcun Farms of Sub tropical Forestry Center, CAF in Fenyi County, Jiangxi Province. It was found that the amounts and species of the actinomycetes in soil of second generation Chinese fir plantation are obviously lower than those in the first generation’s,so do the Bacillus, Azotobacter and Cellulomonas in the bacteria. But in the second generation Chinese fir plantation, the amounts of fungi and the percentage of Agrobacterium, Micrococcus and Chromobacferium in soil bacteria, Penicillium in soil fungi are much higher than those in the first one’s. The amounts of rhizosphere actinomycetes are lower than those in the non rhizosphere’s of both 1st and 2nd generation Chinese fir plantation, yet the amounts of rhizosphere bacteria are the opposite.
