露水河林区地处长白山西北坡,森林资源比较丰富,成过熟林比重很大,而后备资源极少。因此,从长期经营、永续利用原则出发,选择速生树种加快后备资源培育是当前我局森林经营中急需解决的主要课题之一。为此,我局于一九七四年春季开展了北京杨引种试验工作,现早已郁闭成林(见照片),今将试验结果初步总结如下。一、试验地生态地理条件及营造技术试验地位于露水河林业局清水河林场36林班,东经128°,北纬42°30′,海拔高730米。地势比较平缓,南坡,排水较差。土壤为山地暗棕壤,pH值为6.2。年平均气温3.4℃,绝
Lushuihe forest area is located in the northwestern slope of Changbai Mountain, rich in forest resources, into a large proportion of mature forest, and very little reserve resources. Therefore, starting from the principle of long-term management and sustainable development, choosing quick-growing tree species to speed up the cultivation of reserve resources is one of the major topics urgently needed to be solved in our forest management. To this end, our bureau conducted the introduction test of Beijing Yang in the spring of 1974 and it has long been closed to afforestation (see photo). The preliminary results of the experiment are summarized as follows. First, the experimental ecological and geographical conditions and to create technology Experimental site located in Lu Shuihe Forestry Bureau Qingshuihe forest 36 forest classes, longitude 128 ° north latitude 42 ° 30 ’, 730 meters above sea level. Flat terrain, the southern slope, drainage is poor. The soil is dark brown soil with a pH of 6.2. The average annual temperature 3.4 ℃, absolutely
