摘　　要：通过2013年以来4年时间的文冠果引种栽培试验,对文冠果物候期、观赏型品种选育、病虫害及栽培管理等进行观测、归纳、总结,为文冠果观赏型品种的选育奠定理论与实践基础。研究表明:文冠果适宜在北京地区“五一”期间营造观花乔木树种景观。根据文冠果花的颜色,将文冠果的观赏型初步划分为3个系列,即红花系、白花系、粉花系。根据花瓣的单重性,将文冠果划分为单瓣花和重瓣花两大类型。根据盛花期花瓣的特点,将单瓣花进一步划分为紧凑型、离散型、重叠型。根据花的颜色、花瓣的单重性和特点,进一步划分为10个品系,即单瓣白花紧凑型、单瓣白花分离型、单瓣白花重叠型、单瓣红花紧凑型、单瓣红花分离型、单瓣红花重叠型、单瓣粉花紧凑型、单瓣粉花分离型、单瓣粉花重叠型和重瓣白花紫芯型。Through the introduction and cultivation of Xanthoceras sorbifolia for four years since 2013,its phenology,ornamental breeding,pest management and cultivation were observed and summarized to provide the theoretical and practical basis for the breeding of ornamental cultivars of X.sorbifolia.Research shows that X.sorbifolia is suitable for creating a landscape of flowering trees during the May Day in Beijing.According to the color of flowers,the ornamental types of X.sorbifolia are initially divided into three series,namely safflower,white and pink flowers.According to the single weight of the petals,X.sorbifolia’petals are divided into single and double flowers.According to the characteristics of flowering petals,single-petal flowers are further divided into compact,discrete and overlapping types.According to the color of flowers,the single weight of petals and characteristics,X.sorbifolia are further divided into 10 strains,single petal white flower compact type,single petal white flower separation type,single petal white flower overlapping type,single petal red flower compact type,single petal red flower separation type,single petal red flower overlapping type,single petal pink flower compact type,single petal pink flower separate type,single petal pink flower overlapping type and double petal white flower purple core type.
