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10~20 g.m-1为宜。
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.
