通过对朝阳北部风沙区引种樟子松进行系统调查,利用树干解析进行分析,寻找出樟子松生长发育规律,发现其径和高生长有明显阶段性,且生长高峰期都出现在12年左右,并与当地主要造林树种油松和小叶杨进行比较,发现随着林龄增加,樟子松生长比其他两种树种生长逐渐加快,而且林龄越大优势越明显,说明在该地区发展樟子松潜力较大。
Through the systematic investigation on the introduction of Pinus sylvestris var. Mongolica in the northern part of Chaoyang, the paper analyzes the growth and development of Pinus sylvestris var. Mongolica using tree trunk analysis and finds that the growth and development of Pinus sylvestris var. Mongolica have obvious phases and the peak of growth appears in about 12 years , And compared with the main afforestation species Pinus tabulaeformis and Populus simonii and found that with the increasing age, Pinus sylvestris growth than the other two kinds of tree growth gradually accelerated, and the older the greater the advantage of the more obvious, indicating the development of camphor in the region Zi Song greater potential.
