一、环境条件与紅松更新的关系近年来,在小兴安岭林区,进行了大量的红松人工更新工作,并已取得很多成功经验。但也出现成活率不高,生长不良的现象。在天然更新过程中,则常常发现幼苗较多,而幼树较少的现象。分析产生这些现象的原因,除更新技术上还存在一些问题外,环境条件(特別是光、水、热等生态因素)对红松的成活和幼龄期的生长发育影响较大。 First, the environmental conditions and the relationship between Korean pine renewal In recent years, in the small Xingan Mountains, a large number of artificial regeneration of the Korean pine, and has made a lot of successful experience. But there is also a low survival rate, poor growth phenomenon. In the natural regeneration process, you often find more seedlings, saplings less phenomenon. Analysis of the causes of these phenomena, in addition to the update of technology there are still some problems, the environmental conditions (especially light, water, heat and other ecological factors) on the survival of Korean pine and juvenile growth and development greater impact.
