摘要
以5种不同品种桉树土壤为对象,测定了主要微生物类群(细菌、真菌和放线菌)的数量,初步分析了微生物类群的数量与土壤肥力的关系。结果表明,桉树的土壤微生物数量大,且与土壤肥力密切相关;菌类数量比较表明,不同品种桉树土壤肥力大小应为:巨桉>尾叶桉>巨尾桉>尾巨桉>巨赤桉。
The quantity of main microorganism groups （bacteria, fungi and actinomyces）was measured, and the relations between microorganism quantity and soil fertility were preliminarily analyzed. The results indicated that Eucalyptus＇s microbe quantity was huge, and was related to soil fertility. According to the quantity of microorganism groups, it was showed that soil fertility was E. grandis 〉 E. urophylla 〉 E. grandis × E. urophylla 〉 E. urophylla × E. grandis 〉 E. grandis × E. Camaldulensis.
