采用稀释涂布平板培养法,分析比较5种降香黄檀混交林(降香黄檀+檀香、降香黄檀+母生、降香黄檀+火焰木、降香黄檀+沉香、降香黄檀+奥式黄檀)及纯林土壤微生物分布特征.结果表明:各土壤类型微生物数量存在差异,微生物总数以降香黄檀+檀香混交林最多,达112.36×104 cfu·g-1,混交林的土壤微生物总数均显著高于纯林;各类型微生物数量具有明显的垂直变化规律,即土壤微生物主要集中在0 ～ 20 cm土层,随土层加深,微生物数量逐渐下降.各类型土壤微生物数量均表现为细菌＞放线菌＞真菌,土壤细菌数量以降香黄檀+檀香混交林最多,为104.27×104 cfu·g-1;土壤放线菌数量、土壤真菌数量均以降香黄檀+母生混交...

Five different Dalbergia odorifera mixed forest and pure forest was studied conducted to explore the quantities of microorganisms us dilution coated plate culture method. The results showed that：soil microorganism quantity were different among different types of soil,Dalbergia odorifera ＋ Santalum album mixed forest which reached its maximum （112. 36 × 10^4 cfu · g^-1）, and mixed forests in the total number of soil microorganisms were significantly higher than that of pure forest ; soil microorganisms in different models reflected the ver...
