Abstract

Abstract: The aim was to know the dynamic of rhizosphere microbial quantity on colt cherry. Using dilute plate counting method and most probable number method, the dynamic of rhizosphere microbial quantity was studied on annual growth period of colt cherry. The results showed that: there was a positive correlation between the rhizosphere microbal quantity and annual growth stages of colt cherry. Rhizosphere microbial quantity began to rise at germination phase and quickly reached its peak at fruiting, seedling or flowering phase, but decreased slightly later. Microbial quantity in rhizosphere was higher than that of corresponding control except certain periods. The population structure of rhizosphere microbial varied with growth stages, which was the richest at the seedling phase and the smallest at the defoliation phase.
