[Method] Experiments were carried out to study the physical and chemical properties of soil under Dracontomelon duperreranum trees, and soil with- out any fertilizer treatment was used as control. [Result] The results showed that application of humus fertilizer from fermented branches raised the total porosity of soil, and improved the contents of soil organic matter, available phosphorus, rapidly available potassium, the number of soil microorganisms and the activity of soil en- zymes. In addition, the number of soil microorganisms was positively related to the activity of soil enzymes. [Conclusion] Application of humus fertilizer from fermented branches markedly raised the ratio of the number of bacteria to the number of fungi, and promoted the transformation of fungi-rich soil into bacteria-rich soil, which thus significantly enhanced the soil fertility and improved the soil environment under Dracontomelon duperreranum trees.展开更多
