Abstract:

The importance of soil microorganisms can not be ignored in the rhizosphere ecosystem. Change of cultivation measures will affect community structure of rhizosphere, thereby affecting plant growth. Cerasus sachalinensis Kom. showed good performance after grafting for several decades under wild conditions, and Cerasus sachalinensis Kom. was significantly different under cultivation conditions. Therefore, research of the effect of grafting on rhizosphere soil microbial community structure and species diversity of Cerasus sachalinensis Kom. under wild conditions is important to improve the cultural environment and ststainable development of cherry. In this paper, number of rhizosphere bacteria, fungi and actinomycetes, community composition and diversity of the population were studied under the conditions of grafting and the rootstock of Cerasus sachalinensis Kom. in selective medium. The results showed that the effect of grafing Cerasus sachalinensis Kom. was significantly different. Grafing significantly increased number of rhizosphere microorganisms and the formation of Bacillus, Azotobacter, groups of Hygroscopicus, Cinereus, Glaucuc of streptomyces as dominant species groups based; special bacterial genus Escherichia, Arthrobacter, Acinetobacter, Derxi, Staphylococcus found.
