Time for Stratification Mixed with Snow and Reserve Density for Nursery of Phellodendron amurense
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 .
