| 摘 要： | 采用叶面施肥的方法,对黄檗1 a生苗木进行追施氮肥试验,结果表明:施氮肥可显著促进苗木生长,其中以20 g.m-2施肥量效果最为理想,平均苗高38.6 cm,平均地径1.05 cm,平均主根长16.7 cm,平均侧根数29.7个,平均鲜重103.9 g,平均干重30.78 g,分别是对照的111%、144%、132%、182%、149%和148%;20 g.m-2是黄檗1 a生苗木的适宜氮肥追施量。 |

| Abstract: | The effects of nitrogen on the one year old seedling growth of Phellodendron amurense were detected by top dressing with 10 g·m-2,20 g·m-2,30 g·m-2 and 0 g·m-2 pure urea.The results show that optimal application was the treatment with 20 g·m-2.The average height,basal diameter,main root length,lateral root number,fresh weight and dry weight of the seedlings were 38.6 cm,1.05 cm,16.7 cm,29.7,103.9 g,30.78 g,which were 111%、144%、132%、182%、149%和148% higher than the controls. |
