Analysis of the rhizosphere bacterial community and function diversity in cherry orchard of Dalian region
Abstract：The microbial metabolic activity and functional diversities of sweet cherry orchards with clay soil,Sandy loam,Coarse soil in Dalian region were analyzed under Biolog Ecoplate method.The results showed that the amounts of soil microbe,microbial metabolic activity,Substrate richness（S）,Shannon＇s diversity index（H）and Evenness index（J）were clay soil〉Sandy loam〉Coarse soil,and the carbon sources with highest utilization efficiency by soil microbes was carbohydrate in three soil texture.Microbes in the clay soil utilized phenolic compounds with higher efficiency and microbes in sandy loam and coarse soil utilized amines with higher efficiency.The results indicate that soil texture influences soil microbial functional diversity in cherry orchard,and the highest in clay soil,followed by in sandy loam and in coarse soil.But no significant difference was found in microbial metabolic activity,bacterial efficiency of carbon sources,bacterial variety of metabolic activity of three kinds ofsoil texture.Thus,the major factor responsible for bacterial community function diversity in cherry orchards is soil texture.
