Microbial community analysis of apple rhizosphere around Bohai Gulf

Abstract Bohai Gulf is the main area for apple tree cultivation in China. Consecutive replanting significantly affects the yield and quality of apple trees in this area. Microecological imbalance in apple trees’ rhizospheres caused by variation in the soil microbial community is considered the prima...
