Hybrid tulip tree,a famous scemic species,has beautiful flowers and can easi-ly grow into a tall tree. At present,its seedling supplies can't meet the demand.This paper introduced its cutting methods,such as the intermittent spray method in full light,the in-doors glass-case culture and the outdoor polythene greenhouse culture. Using the second method,the current year sprout cutting survival rate can be up to 82.6%,but the propaga-tion coefficient is the lowest and the method is relatively complex. Although the survival rate of the third method is 28.4%,this method is simple,applicable,and can easily be extended.This paper mainly introduces the cutting's propagating method,season, and medium etc.Through using intermittent spray in full light,the cutting rooting rates of the big tree's off-shoots or the young branches can be more than 35% in the beginning of June or the begin-ning of August.
