| Abstract: | By establishing growth model of Populus alba×P.berolinensis were determined fast increment stages of the poplar:6～28_(th) of July for height growth and the fastest day was 17_(th) day;21_(th) of June ～29_(th) of August for breast diameter growth and the fastest day was 25_(th) day of July; 11～17_(th) year for volume growth and the fastest year was 14_(th) year.Therefore was found the dynamic changing rule of growth with time of Populus alba×P.berolinensis. |
