Abstract: The experiment of the containerized seedling cultivation of Qucercus cutissima shows that truncated bud and fertilization can significantly decrease the prolong root,decrease rate of the seedling penetrating container by 37.83%,increase the numbers of branch root by 52.26%,and increase the seedling height,surface biomass and subsurface biomass,and increase the rate of the certified seedling by 25.70%.Except the length of primary root,the correlation between the other characteristics of containerized seedling is significant.
