摘　　要：以红松为材料,在高寒山区进行红松换床育苗试验研究,结果表明:S2-1培育方式改变为S1-2培育方式,苗木长势好,同为3 a生苗,S1-2苗龄型的成苗率达到84.7%,平均苗高19.4 cm,平均地径0.47 cm,完全达到标准规定的出圃苗规格;而S2-1苗龄型的成苗率仅为35.0%,平均苗高14.0 cm,地径0.42 cm,大多数苗木未达到出圃苗标准。A study on seedling cultivation by different methods was conducted in alpine region with Pinus koraiensis.The results showed the S1-2 method was much better than S2-1 method.For 3-years old seedlings,the S1-2 method cultivated seedlings with 84.7% seedling rate,19.4 cm average height,and 0.47 cm base diameter,which reach the standard of nursery seedlings.Conversely,the S2-1 method cultivated seedlings with 35% seedling rate,14.0 cm average height,and 0.42 cm base diameter,most of which did not reach the standard of nursery seedlings.
