西藏林芝地区引种栽培木本观赏植物研究初报

Preliminary report on the introduction of woody ornamentals in Linzhi Prefecture of Tibet

结合西藏林芝地区“福建园”绿化工程建设 ,首次在露地条件下引种栽培了 35种观赏植物。从引种苗木的成活率以及景观表现来看 ,在本次引种中 ,初期生长表现较好的植物有 :碧桃、日本晚樱、紫叶李、垂丝海棠、贴梗海棠、结香、榆叶梅、二乔玉兰、鸡爪槭、腊梅、紫竹等 11种。生长表现良好或一般的植物有 :三角枫、元宝枫、金丝垂柳、火棘、红叶桃、迎春花、美国地锦、紫藤、梅花、重瓣红石榴、红叶小檗、南天竹、红瑞木、白丁香、棣棠、垂枝连翘等16种 ,它们的成活率在 70 %以上 ,对这些植物在栽培中应注意选择适宜的栽培小环境和改进栽培技术方法 ,以便进一步提高栽培成活率。生长表现不佳的植物有 :紫薇、银杏、紫荆、小叶女贞、杜鹃花等 5种 ,对这些植物在景观构建时应慎重使用。而目前在该地区开阔地带不宜种植的主要植物有 :柿、栾树、合欢等 3种。
