摘　　要：研究了不同氮肥处理对东北红豆杉苗木生长的影响,结果表明:施入氮肥能明显地促进东北红豆杉苗木的苗高、干径、冠幅、新生枝条及叶绿素含量的生长,各处理的生长指标均高于对照,其中以4.0g/株处理的各项生长指标表现最为良好,苗木生长旺盛,新生枝条数量多且生长量大。在采穗圃应用此施肥技术,将大大增加种条的数量,培育出更多优质苗木。This paper studied the influence of different nitrogen treatment on the growth of Taxus cuspidata seedlings. The results showed that nitrogen fertilizer could significantly promote seedling height,stem diameter,crown width and chlorophyll content,new shoots growth,growth index of each treatment was higher than that of control. The growth indexes treated with 4. 0 g per plant were the best,the seedlings grew exuberant,the number of new branches was large and the growth was large. The application of this fertilization technology in the spike nurseries will greatly increase the number of species and cultivate more high-quality seedlings.
