- 摘要:
- 为丰富我国观赏针叶树种质资源，进一步提高我国城市园林绿化美化水平，在北京地区引进了‘金羽’桧(Juniperus chinensis ‘Plumosa Aurea’)、‘金锥’欧洲桧(J.communis ‘Gold Cone’)、‘金叶’鹿角桧(Juniperus×media ‘Pfitzeriana Aurea’)、‘蓝星’高山桧(J.squamata ‘Blue Star’)4个观赏矮生型针叶树新品种，对其进行了形态特征、物候期、适应性、观赏性等的引种栽培研究。结果表明：4个针叶树品种在北京地区生长势较强，与沙地柏相比，生长高峰持续时间相对较短，色叶期提前；‘金锥’欧洲桧在北京地区株型发生改变，观赏价值降低；‘金羽’桧在北京地区能安全越冬、越夏，并保持原有叶色、株型等观赏特性，观赏价值较高；‘金叶’鹿角桧和‘蓝星’高山桧观赏价值较高，但越冬期间应提前加强防护措施，需进一步进行抗冷驯化。
- Abstract:
- In order to enrich the ornamental conifer resources in China，and develop urban forestation and landscape，four foreign ornamental conifer species were introduced from Belgium to Beijing，that were Juniperus chinensis‘Plumosa Aurea’, J.communis‘Gold Cone’,J.×media ‘Pfitzeriana Aurea’, J.squamata ‘Blue Star’.Morphologic characters，phenology，ornamental and adaptability of four conifers in Beijing were studied.The results showed that four conifers grew well，and had shorter fast-growth duration and the color of leaves changed ealier compared with Sabina vulgaris Ant.,ornamental of ‘Gold Cone’ had reduced，since changes had taken place in plant form;Conifers were doing well during summer and keep ornamental value including leaf color，plant type among ‘Plumosa Aurea’.‘Pfitzeriana Aurea’and ‘Blue Star’should be protected in advance，and further studied on cold acclimation in Beijing.
