摘　　要：对辽宁东部山区黄波罗播种育苗的混雪层积时间和保留密度进行了研究。结果表明:随混雪层积时间增加,黄波罗种子发芽率和出苗率呈上升趋势,混雪层积145d的发芽率和出苗率最大,分别达到81.35%、64.59%;1年生幼苗保留密度为100株·m-2时,Ⅰ级苗单位产量达到最高。Time for stratification mixed with snow and reserve density of sowing and seedling‐raising for Phelloden‐dron amurense in eastern mountain of Liaoning Province were studied .Result shows that germination rate and emer‐gence of seed for Phellodendron amurense increase with the increase of time for stratification mixed with snow ;the germination rate and emergence are the maximum (being 81 .35% and 64 .59% respectively ) under stratification mixed with snow for 145 d .The reserve density of 1‐year‐old saplings are 100 trees ▌m -2 ,the yield of the first‐grade seedlings reach the highest .
