三峡库区特有植物宜昌黄杨生物学特性观测试验

The Observation Experiment of the Endemic Species of Buxus ichangensis Biological Characteristics in Three Gorges Reservoir

摘要:

摘要：为了促进三峡库区特有植物宜昌黄杨的生存和繁衍，通过开展引种栽培试验，对宜昌黄杨的生物学特性，引入地土壤质地、抗寒性、生长量、病虫害及区域适应性等因素进行综合分析评定，前期的试验结果初步表明：宜昌黄杨在三峡植物园能正常生长发育，4年生苗木平均苗高41.0 cm，平均地径1.7 cm，冠幅29.0 cm2，已开花结实，可作进一步观测试验，为三峡库区特有植物就地保护奠定基础。
