摘要:
为了探究淡紫拟青霉对草莓的促生增产效果及对土壤微生物群落结构的影响,设置淡紫拟青霉接种处理(Q)和对照(CK),采用温室大棚试验测定草莓植株生长指标和盛果期产量,并采用16S rRNA和ITS扩增子测序技术分析草莓根际微生物群落结构,利用Spearman相关系数分析植株指标和微生物数据的相关性。结果表明,淡紫拟青霉能显著促进草莓生长以及果实产量的提高。与CK相比,地上部鲜重和干重分别显著增加44.5%、83.8%,根鲜重和干重分别增加57.1%、65.8%,茎基粗显著增加10.3%,产量显著提高68.8%;淡紫拟青霉接种后细菌群落的Shannon指数、Chao1指数、Ace指数分别显著提高6.9%、150%、9.8%;真菌群落的Shannon指数、Chao1指数、Ace指数分别显著提高30.0%、33.9%、30.0%;淡紫拟青霉接种增加了草莓根际有益微生物RB41属、溶杆菌属、球囊菌门等的相对丰度。共现网络分析表明,淡紫拟青霉接种提高了根际细菌网络的正相关联系及占比,大幅提高真菌网络的连接紧密度和稳定。相关性分析表明,草莓产量与根鲜重、根干重以及真菌Ace指数、酸杆菌门的相对丰度和球囊菌门的相对丰度呈显著正相关。综上,淡紫拟青霉对草莓具有良好的促生增产效果,并能重组草莓根际微生物群落结构,提高土壤细菌和真菌的多样性,使微生物网络结构(特别是真菌网络)更加紧密和稳定。
