摘要:
以红托竹荪为试材,将其套种于15年生油茶林下,通过对油茶根围土壤理化分析和高通量测序,研究该套作系统对土壤肥力和微生物多样性的影响。结果表明:套种后油茶根围土壤的综合肥力指数提高20.27%,等级提升1级,由贫瘠变为一般肥力水平;套种显著提高了土壤微生物群落中真菌的Sobs、ACE、Chao指数和细菌的Simpson指数,降低了真菌的Simpson指数和细菌的ACE指数,从而增加了真菌的多样性、丰富度,降低了细菌的多样性和丰富度;套种显著提高了土壤真菌的β多样性距离值,从而丰富了β多样性;套种改变了土壤中微生物的群落结构,丰度均值差最大的真菌属和细菌目分别为木霉属和酸杆菌目,对套种后土壤微生物物种组成影响最大的真菌和细菌分别是木霉属和芽孢杆菌。群落结构的差异使其注释的酶功能也有差异,套种后含磷基团转移酶丰度增加。综上,套种红托竹荪能提升油茶根围土壤的综合肥力和微生物多样性,并改变微生物群落结构及相关酶类功能性,其中标志性差异物种和相关酶类可为挖掘下一步影响机制奠定基础。
