摘　　要：核桃楸(Juglans mandshurica Maxim.)是东北地区三大珍贵硬阔叶用材树种之一,也是东北地区的造林树种。床播时,核桃楸育苗密度决定苗木的产量和质量,试验结果表明,当密度达到110株/m2时,是核桃楸的最优育苗密度,其苗高、地径、主根长、侧根数最优,有利于优质壮苗的培育。Juglans mandshurica is one of the precious three hardwood timber tree species in the northeast, it is also an afforestation tree specie in the northeast. The seedling density determines the seedling yield and quality in the bed sowing. The test results showed that：The best seedling density was 110 per square meter in the seedling cultivation of J. mandshurica, the seedling height, ground diameter, root length and the number of lateral root were optimal, it was beneficial to the cultivation of high quality seedlings.
