摘　　要：白玉山楂枝条角度开张,密度大,树荫大,春季白花繁密,夏季叶色浓绿,秋叶转橘黄色,冬季粉红色果实长久不落,是良好的城市园林绿化树种。采用播种育苗方式培育苗木,出苗率低,生长速度慢,结实晚,不能尽快满足绿化需要。以山里红做砧木,采用嵌芽接和劈接法培育嫁接苗可以解决以上矛盾,尽快达到绿化效果,满足生产需要。Crataegus ctus-galli with its unique biological habitats,aesthetic value and hardiness,was becoming a kind of famous landscape trees.Using seedling propagation method to cultivate seedlings has some drawbacks： lower germination rate,slow growth,late stronging,can＇t meet the greening needs.Making Crataegus pinnatifida bunge as rootstocks,using bud-grafting and cleft-grafting techniques,can avoid the the above shortcomings,meanwhile meeting the effect of urban greening and production needs.
