摘　　要：通过在辽宁东部山区黄波椤圃地播种育苗中开展不同种子处理方法、苗木不同保留株距的对比研究。结果表明:混雪层积处理150 d的种子发芽效果最好,发芽率达到70.55%,出苗率达到55.37%,出苗整齐,苗木质量好。不同保留株距对1年生黄波椤播种幼苗的苗高、地径生长影响差异极显著,以保留株距为8~10 cm的处理较适宜。A comparative study on different methods of seed germination and plant spacing was conducted in Phellodendron amurensis nursery in the eastern mountainous area of Liaoning Province.Result shows that the optimal effect of mixed snow stratification treatment is 150 days,the germination rate of seeds reach 70.55%,the emergence rate reach 55.37%,the emergence of seeds is neat,and the quality of seedlings is optimal.The effect of different plant spacing on the height&ground diameter growth of one-year-old Phellodendron amurensis seedlings is significant(P<0.01 and P<0.05).When considering the three indexes of seedling height,ground diameter&first-class seedling yield at the same time,it is suitable to keep the plant spacing of 8 cm-10 cm.
