毛竹种植对土壤细菌和真菌群落结构及多样性的影响
Effects of Phyllostachys edulis cultivation on soil bacterial and fungal community structure and diversity
摘要
Abstract
This study examined how soil bacterial and fungal communities responded to the cultivation history of Moso bamboo in Anji and Changxing counties,Huzhou,Zhejiang,China.Soil samples (0-20 and 20-40 cm) were taken from bamboo plantations subjected to different cultivation histories and analyzed the community structures of soil bacterial and fungal by PCR-DGGE methods.It was found that soil bacterial and fungal communities varied greatly with the development of bamboo plantations which converted from Masson pine forest or formed via invading adjacent broadleaf shrub forest.Soil bacterial community structures exhibited a greater response to bamboo cultivation time than fungal community,but bacteria structure of surface soil displayed an ability of resiliency to disturbance and the tendency to recover to the original state.The cultivation time,sampling site and soil layer significantly affected the biodiversity of soil bacteria and fungi,especially the latter two factors.Redundancy analysis (RDA) of soil properties and bacteria or fungi communities showed that there were no accordant factors to drive the alteration of microbial structure,and the first two axes explained less than 65.0％ of variance for most of the sampling sites and soil layers,indicating there existed soil parameters besides the five examined that contributed to microbial community alteration.关键词
