摘要
本文报道了在沈阳地区采用地膜覆盖方法进行杜仲育苗的试验情况。结果表明，地膜覆盖育苗较对照育苗的出苗时间提早１４～１５ｄ，出苗率提高２４０％～２６６％，１年生苗平均增高１５２ｃｍ，地径增粗０１２ｃｍ，幼树越冬受害率降低１０６％。
Experiment of eucommia ulmoides seedling cultivation by film cover in Shenyang region is reported in this paper. The result shows that soil film has good effects on growth of the seedlings. Compared with check,seedlings under film cover appeared 14-15 d earlier and production increased 24 0%-26 6%.
