In order to explore the suitable breeding technologies of Xanthoceras sorbifolia Bunge in arid region of northwest China,a comparative study on main propagation methods (sowing propagation,rooting propagation,grafting propagation) of X.sorbifolia was conducted in 2014—2016 based on the reproductive materials of X.sorbifolia fine individuals selected in Gansu.The results showed that,1) The survival rate of rooting propagation was the highest,with an average survival rate of 75.33%;The average emergence rate of sowing propagation,reached 50%;The grafting propagation was worse and its average survival rate was only 27.40%.It showed that the rooting propagation and the sowing propagation were suitable for the large-scare breeding of X.sorbifolia.2) The seedling emergence rate was nearly the same for two different sowing methods of plastic film mulch sowing and field direct sowing,their average emergence rate was 51.31% and 51.10% respectively.It indicated that the X.sorbifolia can be sowed directly in the field.3) During the seed germination of mulching sowing and field direct sowing,their seed germination was not coincident.4) Due to the influence of stock quality and low temperature on grafting,the survival rate of grafting propagation was low.Under the conditions of drought,water shortage and big wind in northwest area,it is regarded that X.sorbifolia had better sow with plastic film mulch,the seeds had better make treatment before sowing,the grafting had better adopt low stock and earth up around scion or cover plastic bag on scion after grafting.
