摘要:
为探讨生物有机肥稻田水稻不同生长时期根际土壤细菌群落动态变化及其和环境因子的相关性,利用高通量测序技术对生物有机肥稻田水稻分蘖期、拔节期、抽穗期和成熟期4个时期的根际土壤细菌进行高通量测序及分析。结果显示,测序共获得404 183个有效序列,可分为55个门,171个纲,385个目,603个科,1 010个属,2 139个种。α多样性分析显示,ACE多样性指数在生长时期呈现先下降后上升的趋势,分蘖期和拔节期的香农多样性指数均与成熟期差异显著。4个生长时期的优势菌门相似,优势菌门(相对丰度>10%)有放线菌门(Actinobacteriota)、绿弯菌门(Chloroflexi)、变形菌门(Proteobacteria)和酸杆菌门(Acidobacteriota)。β多样性分析显示,4个生长时期的细菌群落结构具有一定的差异性,成熟期和其余3个时期的群落结构差异显著。冗余分析(RDA)表明,pH值是影响细菌群落的第1因子,主要菌门都与pH值呈正相关,其中绿弯菌门受pH值影响最大。相对丰度值最高的放线菌门则受含量影响最大。在生物有机肥稻田中,随着水稻的生长发育,根际土壤的细菌群落结构会随着土壤理化因子发生一定变化,说明土壤理化因子是影响细菌群落的主要因素。
