[目的]研究树枝发酵腐殖质肥对人面子林下土壤pH、总孔隙度、有机质含量、碱解氮、有效磷、速效钾、土壤微生物数量以及土壤酶活性的影响。[方法]以不施任何肥料为对照，对人面子林下土壤进行理化性质分析。【结果】树枝发酵腐殖质肥能增加总孔隙度，能显著增加土壤有机质、碱解氮、有效磷、速效钾含量、土壤微生物数量和土壤酶活性，土壤微生物数量与土壤酶活性显著正相关。[结论】施用树枝发酵腐殖质肥能提高人面子林下细菌同真菌数量的比值，促使土壤由真菌型向细菌型方向转化，且提高了微生物数量和土壤酶活性，从而显著提高人面子林下土壤肥力，改善土壤环境。

[Objective] This study aimed to explore the effect of humus fertilizer from fermented branches on pH, total porosity, contents of organic matter, alkaline hy- drolysable nitrogen, available phosphorus, rapidly available potassium, the number of microorganisms and the activity of enzymes in the soil under Dracontomelon duper- reranum trees. [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.
