为探究不同改良方法对人参连作土壤养分、酶活性及真菌群落结构的影响,实验以未处理的老参地土壤(LSD)为对照,设置高温下施加碳酸氢铵(CS)和以五灵脂为碳源(WLZ)的强还原土壤灭菌处理2个处理组,采用化学分析和高通量测序技术分析土壤的理化性质和真菌群落的变化。 结果表明: 与LSD处理相比,2个处理组均提高了土壤pH值、有机质(OM)、速效磷(AP)和碱解氮(AN)等养分含量以及脲酶(URE)和酸性磷酸酶(ACP)酶活性,同时降低了土壤真菌群落丰富度,从各土壤样本中共检测到44门113纲204目308科480属。 相关性分析表明,土壤养分含量OM、AP、AN和pH值均密切影响真菌群落的变化。 2种处理均能改善土壤营养状况,重构真菌群落,2种方法单独应用均有效,未来可探索协同作用,这有望成为修复退化土壤的新途径。
