| 摘 要： | 以黄檗种子和1 a生播种苗为材料,研究不同沙藏层积时间对发芽率与出苗率和不同播种密度对苗高与地径生长的影响,结果表明:当沙藏层积时间达到150 d时,种子发芽率和出苗率均最高,分别为80.85%和64.09%;当播种密度为90株·m~(-2)时,单位面积Ⅰ级苗产量最高,达到96.15%。

| Abstract: | The effect of different sand storage stratification time and seeding density on germination rate and emergence rate and the growth of height and ground diameter by taking the Phellodendron amurense seeds and 1 year seedling as materials.The result showed that the germination rate and emergence rate of seeds which was 80.85 % and 64.09 % was the highest when the sand storage stratification time was 150 d.The yield of Ⅰ level of unit area was 96.15 % which was the highest when the seeding density was 90 plant per square meter. |
