Changes of Microbial Community Structure on Flue-cured Tobacco Soil Rhizosphere in Different Cropping Systems
摘要
Abstract
To solve the yield reduction and quality brought by continuous cropping,promote sustainable development of flue-cured tobacco production,the change of microbial community structure on flue-cured tobacco soil rhizosphere in the different cropping systems was studied.The results showed that the similarity of flue-cured tobacco continuous cropping system in two and five years was higher for bacterial community structure.There were big differences for bacterial community structure with ＇soybean-maize-flue-cured tobacco＇ and ＇maize-soybean-flue-cured tobacco＇,while ＇soybean-wheat-flue-cured tobacco＇ was middle.As for fungi community structure,the ＇soybean-wheat-flue-cured tobacco＇,＇soybean-maize-flue-cured tobacco＇ and ＇maize-soybean-flue-cured tobacco＇ were highly similar.The flue-cured tobacco continuous cropping system in two and five years was changed and the continuous change of 5 years was bigger.Therefore,the micro-organisms community structure of flue-cured tobacco continuous cropping,especially the change of rhizosphere fungi community structure may play an important role occurred in flue-cured tobacco continuous cropping obstacles.关键词
