摘要: 以托克托县一间房苗圃的土壤为研究对象,通过稀释涂布平板的方法对不同土地利用方式下的土壤可培养微生物数量的特征进行研究。结果表明:(1)不同的土地利用方式下,土壤可培养微生物的数量差异性显著,林地中放线菌、固氮菌的比例高于细菌、真菌,农田中细菌、放线菌的比例明显高于真菌、固氮菌。(2)同一土地利用方式下,4种土壤可培养微生物的数量随着土壤深度的增加大致呈现下降的趋势。(3)不同土地利用方式下,相关性分析表明土壤可培养微生物类群之间的相关性不同,然而细菌与真菌之间都存在极显著的正相关关系(P〈0.01)。

Abstract: To study the effects of different land use patterns on soil cultivable microorganisms in the Yijianfang nursery.The numbers of soil cultivable microorganisms were determined using dilution plate method.The results showed that:(1)under different land use patterns,the number of soil cultivable microorganisms was significantly different.The proportion of actinomycetes and nitrogen-fixing bacteria in woodland was higher than bacteria and fungi,the proportion of bacteria and actinomycetes in farmland was significantly higher than fungi and nitrogen-fixing bacteria.(2)the number of soil cultivable microorganisms decreased in the same land use pattern while soil depth increased.(3)by the correlation analysis,the correlation was different in soil cultivable microbial community,moreover,there existed an especially positive correlation between bacterial and fungal indifferent land use patterns(P〈0.01).
