红松是东北东部山地的地带性植被类型——红松阔叶林的主要建群树种。由于其经济价值很高,也是该地区最重要的森林更新树种之一,已经有很多学者进行着多方面的研究。本文就五年多的试验研究工作做一总结,试图回答红松人工幼林在有上层林冠的条件下,是否应该一次全部伐去上层林冠?透光与施肥和施土面增温剂相比较,哪种措施对红松生长影响较大?在光照条件基本一致的前提下,施肥和施土面增温剂与未进行任何措施的对照区比较,哪个因子更为重要?
Korean pine is a type of zonal vegetation in the northeastern part of Northeast China - the main tree species of korean pine broad-leaved forest. Due to its high economic value and its being one of the most important species of forest regeneration in the region, many scholars have conducted various studies. In this paper, a summary of more than five years of experimental research to try to answer the Korean pine young plantations in the upper canopy conditions, whether it should be a total cut to the upper canopy? Translucent and fertilization and application of soil warming agent compared, What kind of measures have greater impact on the growth of Korean pine? Under the premise of basically the same light conditions, which factor is more important than fertilization and soil warming agent compared with the control area without any measures?
