于1984年在东北林业大学帽儿山实验林场老爷岭森林生态定位站,对水曲柳的种群扩散及存活进行研究。研究结果,天然落叶阔叶林埋藏种子生活力为30％—50％,人工落叶林下为58％。新采水曲柳成熟翅果,秋播于人工落叶松林土壤的部位不同,其1 a幼苗转化率、2—4 a幼树保存率均差异明显,以播在A_0层下、A_1表层者为优,由秋播至萌发的转化概卒为0.38;1,3,4年生幼苗幼树的保存率分别为0.33,0.29,0.25。该数字高于育苗规程的播种量转化为1年生苗的要求。
In 1984 at the Mao’ershan Experimental Forest Farm, Northeast Forestry University, Laoyeling forest ecological positioning station, the population spread and survival of Fraxinus mandshurica. The results showed that the seed germination capacity of natural deciduous broad-leaved forest was 30% -50%, artificial deciduous forest was 58%. Freshly planted mature mandarin (Samara) fruit, autumn sown in the artificial Larix gmelinii different parts of the soil, the 1 a seedling conversion rate, 2-4 a sapling preservation rate were significantly different to sow A_0 layer, A_1 surface layer is Excellent, the transformation from autumn sowing to germination was 0.38; 1, 3, 4-year-old seedling sapling conservation rates were 0.33,0.29,0.25. This number is higher than the nursery schedule of seeding into one year seedlings requirements.
