不同迹地更新红松的效果分析

Effects of Regeneration for Pinus koraiensis on Different Slash

对不同迹地类型更新红松进行了试验研究,结果表明,红松与落叶松迹地更新红松成活率和保存率不足80%,幼树生长不良,土壤养分含量低,林木质量低劣,而次生林和荒山荒地迹地更新红松,成活率和保存率在90%以上,林木生长迅速,根系发达,土壤养分含量较高,林木质量优异。所以今后营造红松速生丰产林,应以次生林和荒山荒地迹地为宜。

Regeneration of Pinus koraiensis on different types of slash was studied.Result shows that regeneration for Pinus koraiensis on slash of Pinus koraiensis Larix spp.lead to：survival preservation rate are less than 80%,saplings grow poor,nutrient content of soil is low,and quality of trees is poor;while regeneration for Pinus koraiensis on slash of the secondary forest barren hills and wasteland,survival preservation rate are above 90%,trees grow fast,root system develope,soil nutrient content is high,and forest quality is excellent.So in the future,to create a fast growing forest of Pinus koraiensis,slash on secondary forest barren hills wasteland should be appropriated.
