| 摘 要： | 研究了内蒙古荒漠草原土壤中主要微生物类群的数量随季节变化的规律，以及土壤中微生物的垂直分布特征．结果表明，土壤中3大类群微生物的数量关系为细菌〉放线菌〉真菌，各类群微生物的垂直分布均为0～10cm层多于10-20cm层．细菌、真菌、自生固氮菌以及微生物总数量的峰值出现在春季，而放线菌数量的峰值出现在秋季．

| Abstract: | Seasonal fluctuation and distribution in different soil layers of the main soil microorganisms in the soil of Stipa breviflora desert steppe of Inner Mongolia were studied. The results showed that numbers of the soil microorganisms is bacteria;aetinomyeeto;fungi,which are higher in the 0; 10 em soil layer than that in the 10;20 cm soil layer. The numbers of baeteria,azotobaeter and fungi are the highest in spring,but the numbers of actinomyceto are the highest in autumn. |
