金沙江干热河谷区原生观赏植物筛选与繁育应用

Selection and Breeding Application of Native Ornamental Plants in the Dry-hot Valleys of Jinsha River

通过金沙江干热河谷区植物群落的深入调查,从树型、花、叶、果等多种因子进行综合评定,筛选出景观价值高的原生观赏植物30种,对筛选出的冬樱花、滇榄仁、木蝴蝶等12种原生植物进行繁殖和轻基质培育试验,找出最佳繁育方法,培育苗木10万株,推广应用于攀枝花城市视野区的山体生态治理、植被恢复和森林质量提升等城市森林建设工程,营建了1500 hm^2生态景观林,为金沙江干热河谷类似地区山体生态治理、原生植物开发利用提供参考资料。

This paper conducts an overall evaluation and selects 30 native ornamental plants of high landscape value in terms of tree shape,flowers,leaves and fruits by investigating the plant communities in the dry-hot valley of Jinsha River.Then,it conducts breeding experiments and medium cultivation among 12 selected native plants including Prunus majestica Koehne,Terminalia franchetii Gagnep,Oroxylum indicumVent and etc.,which aims at finding out the optimum breeding method.This program has cultivated 100,000 seedlings to promote the construction project of urban forest such as ecological management of mountains within the vision area of Panzhihua,vegetation restoration and forest quality improvement.It has created an ecological landscape forest of 1500 hm^2 in order to provide reference to the ecological management of mountains and exploitation of native plants in dry-hot valleys.
