摘要:
连作障碍对牡丹的生长发育会产生严重的影响,根际微生物环境会对这种改变做出相应的反馈,因此,对连作状态下的不同种植年限凤丹牡丹根际微生物环境的研究有重要意义。采用Illumina 高通量测序技术,以苏州地区的3、6、10年生凤丹牡丹根际土壤为研究对象,对根际真菌群落进行测序分析,研究真菌ITS rDNA可变区的丰富度和多样性指数。测序后不同种植年限根际土中共得到1 020 520条原始序列,序列过滤拼接后可得613 250 条序列(tags);3组土壤样品共含有891个分类操作单元(OTUs),涵盖了5 门、115纲、15目、175 科、230属、320种菌群;3年生凤丹牡丹根际优势菌群为球囊菌门(Glomeromycota)、木耳科(Auriculariales)、盘菌科(Pezizaceae)、球腔菌科(Mycosphaerellaceae);6年生凤丹牡丹的优势真菌群落主要有肉座菌目(Hypocreales)、鬼伞属(Coprinopsis)、巢菌科(Nidulariaceae)、黑蛋巢菌(Cyathus)、银耳目(Tremellales);10年生凤丹牡丹的优势真菌群落主要有丝膜菌属(Cortinarius)、蜡皮马鞍蜡壳菌(Helvellosebacina)、革菌属(Thelephora)。α多样性分析和β多样性分析均表明,不同种植年限凤丹牡丹根际土菌群群落多样性所呈现的规律为6年生>3年生>10年生。此外还发现,在连作状态下不同种植年限的凤丹牡丹根际真菌群落多样性之间有显著差异,菌群群落多样性呈先升高后降低的趋势。
