在砚山铳卡不同立地条件下栽培试验的初步结果表明 :川滇桤木在滇东南岩溶山区的石山和土山、石灰土和山地红壤上生长都比较好 ,表现出对不同立地条件较强的适应能力 ,其生长快慢与立地条件的好坏密切相关。川滇桤木的树高、地径、冠幅、叶面积、叶长、叶宽、单叶鲜重、干鲜重、枝叶鲜重和生物量等 10个生长性状具有较高的一致性。川滇桤木具有育苗周期短、生长迅速、适应性强的特点 ,是岩溶山区营造生态防护和水源涵养林的一个优良树种 ,2年生平均树高为 1 7m、地径为 2 5 8cm、冠幅为 0 85cm ,树高最大达 5 1m、地径最大达 7 3cm。
The preliminary results of the cultivation experiments under different habitats of Yanshancaojia showed that the Alnus mandshurica trees grew well in the rocky and mountainous areas, the limestone and the mountainous red soil in the southeastern Yunnan Karst mountainous areas, and showed good growth on different site conditions Adaptability, its growth is closely related with the site conditions. The tree height, diameter, crown width, leaf area, leaf length, leaf width, fresh weight of single leaf, dry weight, fresh weight of branch and leaf and biomass of 10 species of Alnus cremastogyne have higher consistency. Sichuan Dianmu has the characteristics of short seedling growth period, rapid growth and strong adaptability. It is an excellent tree species for ecological protection and water conservation forest in karst mountainous areas. The average tree height of two-year-olds is 17 m and the diameter is 25.8 cm The width is 0 85cm, the maximum height is 51m and the maximum diameter is 7cm.
