| 摘 要： | 从落叶松（Larix gmelinii Rupr.）苗木高径比分配、造林成活率和幼苗高生长的关系进行试验,研究得出落叶松育苗密度以300-400株/m^2最好,把苗木按等级分为优质苗、中等苗和劣质苗,也得出了育苗中40∶1和50∶1的苗木为最佳高径比。

| Abstract: | To research the relationship between the distribution of height to diameter ratio,survival rate and seedling height growth of Larch seedlings,derived from such studies：Larix gmelinii Ruor.seedling density of 300～400planta/m2 be the best,divid the seedlings into high-quality seedlings middle,and inferior by grade,come to the nursery seedlings in the 40∶1 and 50∶1 aspect ratio for the best. |
