摘要
藏柏原产我国西藏东部及南部的墨脱、林芝等地区,黔西县自2004年开始引种以来,藏柏七年树龄平均生长高度为676cm,树高年平均生长量为86.28cm,米径年平均生长量达0.94cm,在相同立地条件下,藏柏的树高、米径生长量为本地柏木的1.6倍和1.5倍,结果表明藏柏在黔西县有较强的适应性和速生性,对黔西县石漠化治理和荒山荒坡水土保持的治理有其重要意义。
Studies show that the seven-year-old Cupressus torulosa＇s average growth height has reached 676cm,average annual growth of tree height has reached 86.28cm and average annual growth of meters diameter has reached 0.94cm since they were introduced to Qianxi county in 2004.At the same conditions,compared with local cypress,the tree height and the Meters diameter growth of cupressus torulosa are 1.6 times and 1.5 times.It shows that cupressus torulosa has strong adaptability and ability of growth in Qianxi county and has important meaning for rocky desertification controlling and water and soil conservation on the barren hills.
