摘要
对华山松在云龙县漕涧地区的造林技术进行了研究,结果表明:在漕涧地区,华山松适宜于海拔2000～2800m的微酸性棕壤或黄棕壤,选用天然母树林采种并进行品质检验后育苗,100d出圃,雨季植苗造林,成活率达95%,且比直播造林节约种子1倍以上。
The afforestation technology of Pinus armandi Franch in Caojian area of Yunlong county is stud- ied in this paper. The result shows：In Caojian area, Pinus armandi Franch is suitable for the slight--acidity brown loam or yellow--brown loam in 2000--- 2800 m areas above sea level. After collecting seedlings from the natural seed trees and examining their qualities, the seedlings are moved to the nursery garden, and can be living outside a 100 days. Besides, planting seedlings and afforesting in raining season,the survival rate can be up to 95% ,and it also can save seedlings once above than direct seeding.
