| 摘 要： | 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2.58cm、冠幅为0.85cm,树高最大达5.1m、地径最大达7.3cm.

| Abstract: | The results of cultivation experiment carried out at Chongka experimental basis of Yanshan county showed that Alnus sp.had good adaptability to the vary site conditions of karst mountain area in southeastern Yunnan,including stony mountain,limestone soil and mountain red soil.The growth speed varied with the site condition.Ten growth indexes,namely tree height,diameter at ground,crown width,leaf area,leaf length,leaf width,fresh weight of leaf,fresh weight of stem,fresh weight of branches and leaves,biomass were correlated.With the advantages of short seedling raising cycle,rapid growth and adaptability,Alnus sp was an idea species for protection forests and water conservation forests in karst mountain area.The average tree height,diameter at ground and crown width of 2 years old Alnus sp were 1 7m,2 58cm and 0 85m respectively.The highest value of tree height and diameter at ground attained 5 1m and 7 3cm respectively |
