红松幼树移栽更新试验效果的研究

Effect of Regeneration Experiments of Transplanting Pinus Koraiensis Saplings

为迅速发展红松果材经济林,尽快满足市场对红松产品的需求,开展了红松不同林龄移栽试验,结果表明:红松移栽成活率能达到80%以上,5年后保存率达到70%以上;红松移栽后2年内生长缓慢,以后生长逐渐加快,并能很快恢复到保留树的生长速度;红松移栽后林木分化遵从正态分布,优势木随年龄增大逐渐占30%左右,不良木在林分中占10%～20%。

In order to rapidly develop Pinus Koraiensis fruit timber forest,as soon as possible to meet the market demand for the product of Pinus Koraiensis, transplanting experiment of Pinus Koraiensis with different forest ages were conducted;result shows that： the survival rate can reach above 80%, preserving rate being above 70%. Pinus Koraiensis grow slowly after two years＇ transplanting and then gradually accelerate growth; it can be quickly restored the growth rate of the preserved tree; forest differentiation of Pinus Koraiensis comply with normal distribution after transplanting; the dominant trees constitute about 30 % with the increase of the age, poor wood constitute 10%-20% in stands.
