红松皆伐迹地更新红松的效果分析

为了探讨红松皆伐迹地更新红松的效果,对红松皆伐迹地更新的红松的生长情况进行了调查研究,结果表明：红松皆伐迹地更新红松效果不良,无论是胸径还是树高,其生长量都比较缓慢,荒山荒地更新的红松,胸径生长量比红松皆伐迹地高32%,树高生长量高62%;红松皆伐迹地的土壤理化性质均不如荒地,针叶N、P、K的含量和叶面积指数皆低于荒地,更新10年后根系的分布,无论是水平分布还是垂直分布,都远不如荒地的更新效果。建议对红松皆伐迹地应该培养人工阔叶林或人工针阔混交林。

Effects of Regeneration of Pinus koraiensis in Clear-cutting Site

To investigate effects of reforestation of Pinus koraiensis in clear-cutting site ,the grow th of regeneration of Pinus koraiensis in clear-cutting site were investigated .Result shows that ：the effects of regeneration of Pinus ko-raiensis in cleared area is not good ;whether DBH or tree height ,its growth is relatively slow ;DBH height growth of regenerated Pinus koraiensis in barren wasteland are 32% 62% respectively than that in clear-cutting site .Soil properties of Pinus koraiensis in clear-cutting site are all not as good as wasteland ;N ,P ,K content leaf area index of coniferous trees are all lower than that of wasteland ;root distribution after regeneration 10 years later , whether horizontal or vertical distribution ,are far inferior to regeneration effects of wasteland .Artificial broad-leaved forest or artificial conifer should be cultured in clear-cutting site of Pinus koraiensis .
