在落叶松种间初步选择的基础上,进一步开展适地适种源试验,这不仅是解决造林保存率低,生长不良的重要措施,也是树木改良的重要基础。 长白落叶松分布以吉林省的长白山为中心,仅向东北延伸到黑龙江省的张广才岭。其分布范围约在北纬41°30′—45°20′,东经126°30′—131°40′。现已成为东北地区造林
Based on the preliminary selection of larch species, the further development of suitable provenance test is not only an important measure to solve the problem of low preserving rate and poor growth, but also an important foundation for tree improvement. Changbai larch distribution to Changbai Mountain in Jilin Province as the center, extending to the northeast only Zhang Guangcai Ling in Heilongjiang Province. Its distribution range is about 41 ° 30’-45 ° 20’N and longitude 126 ° 30’-131 ° 40’E. Has now become afforestation in the northeast region
