, a prominent species of edible oil tree in China, depends on improved soil fertility for its sustainable growth. Although the application of bacterial manure has been demonstrated to enhance soil nutrient conditions, the specific contributions of endophytes within fertilizers and their interactions with soil microbial ecosystems remain inadequately explored. This study investigates the impact of organic fertilizers combined with three endophytes (CoT10, CoH27, and CoH17) on the physicochemical properties, enzymatic activities, and microbial diversity of soils in plantations. Findings indicate that the integration of endophytes with organic fertilizers significantly improved soil nutrient levels (including total nitrogen, total phosphorus, and hydrolysable nitrogen), enzymatic activities (such as phosphatase, amylase, and nitrate reductase), and microbial diversity compared to the application of organic fertilizer alone. Notably, the endophyte CoT10, when applied alone with organic fertilizer, resulted in increased levels of total nitrogen, total phosphorus, and hydrolysable nitrogen in the soil, as well as a marked enhancement in the activities of soil phosphatase, amylase, and nitrate reductase. Furthermore, the combination of CoT10 with other endophytes in organic fertilizer improved the functionality of the other microorganisms and the efficiency of organic fertilizer utilization. This study underscores the synergistic effects of endophytes and organic fertilizers, providing scientific insights and practical strategies for the sustainable cultivation of .
是中国一种著名的食用油树品种，其可持续生长依赖于土壤肥力的改善。尽管已证明施用菌肥可改善土壤养分状况，但肥料中内生菌的具体作用及其与土壤微生物生态系统的相互作用仍未得到充分研究。本研究调查了有机肥料与三种内生菌（CoT10、CoH27和CoH17）组合对人工林土壤理化性质、酶活性和微生物多样性的影响。研究结果表明，与单独施用有机肥料相比，内生菌与有机肥料的结合显著提高了土壤养分水平（包括全氮、全磷和水解氮）、酶活性（如磷酸酶、淀粉酶和硝酸还原酶）和微生物多样性。值得注意的是，内生菌CoT10与有机肥料单独施用时，导致土壤中全氮、全磷和水解氮含量增加，同时土壤磷酸酶、淀粉酶和硝酸还原酶的活性显著增强。此外，CoT10与有机肥料中的其他内生菌组合提高了其他微生物的功能和有机肥料的利用效率。本研究强调了内生菌与有机肥料的协同效应，为的可持续种植提供了科学见解和实用策略。
