摘要
大豆根系土壤中,细菌数量最多,其次为放线菌,真菌数量最少,其群体数量受土壤pH值影响较大。大豆根际土壤微生物总数明显高于大豆根外土壤微生物总数,土壤湿度对微生物习性及繁殖有决定性效应。
The research shows that in soybean root system of the soil, bacterium is the most, actinomyces is the middle and fungus is the least in quantity. And the population quantity is infected with pH value greatly. The total of soil microorganism in rhizosphere is obviously higher than in exoroot, soil humidity plays a decisive role in the habit and propagation of soil microorganism.
