| 摘 要： | 通过对黄菠萝（Phellodendron amurense Rupr．）1年生苗木施钾肥的试验研究，结果表明：钾肥不同施肥量对苗木的苗高、地径和生物量等主要指标有明显的影响。苗高比对照提高11．6％～28．1％，地径提高21．9％～30．1％，干物质积累量增加42．8％～108．0％，施肥量以10～20g·m^-1为宜。

| Abstract: | Experiments of 1-year-old Phellodendron amurense applied potassium fertilizer were conducted.Result shows that different fertilizer amount have significant effect on seedling height,DBH and biomass of seedlings.Seedling height,DBH,and dry matter accumulation increases by 11.6%-28.1%,21.9%-30.1%,42.8%-108.0% than CK respectively.The optimal fertilizer rate is 10-20 g · m-1. |
