摘要:
为了探究药用植物种植年限对土壤根际真菌多样性的影响和根际群落结构的差异,从根系与土壤微生物关系角度为药用植物的生产实践提供理论基础,采用Illumina Miseq测序平台分析不同种植年限龙胆草根际土壤的真菌群落。结果表明,测序获得的1541个OUT分属于11门28 纲59目109科173属。与未种植龙胆草的土壤相比,龙胆草土壤根际真菌群落的丰度和多样性指数降低,并且随着种植年限的增加,多样性与生长年限呈负相关,根际真菌群落丰度和多样性指数的下降趋势明显。种植年限影响根际真菌群落结构的改变,种植2、3年龙胆草土壤根际真菌群落结构相似,与种植1年的根际真菌群落结构差距较大。随着种植年限的增加,根际真菌优势种群由未种植中小球腔菌属(Leptosphaeria)等有益菌属为主转变为种植3年的炭疽菌属(Colletotrichum)、镰刀菌属(Fusarium)等致病菌属。可以看出,种植龙胆草影响了根际真菌群落多样性和群落结构,随着种植的年限增加,有益菌属丰度下降,致病菌属丰度增加。
