依据相同立地条件下同龄人工林样地调查数据,分析比较思茅松扦插苗与实生苗造林效果的差异。结果表明:1)实生苗造林保存率比扦插苗高,但两者均高于90%;2)扦插苗的树高、地径生长量比实生苗大;3)扦插苗及实生苗高生长和径生长之间存在极显著的正相关关系,扦插苗表现出“高胖”的形态特征,而实生苗倾向于“矮胖”。
Based on the survey data of the same-age artificial forest plots under the same site conditions, the differences in the afforestation effects between the cuttings and the seedlings of Pinus kesiya pine were analyzed. The results showed that: 1) The preservation rate of seedlings was higher than that of cutting seedlings, but both were higher than 90%; 2) The height of tree cutting and diameter growth of cuttings were larger than that of seedlings; 3) There was an extremely significant positive correlation between the growth and the diameter of the cuttings. The cuttings showed “high fat” morphological characteristics, while the seedlings tended to be “short and fat”.
