摘　　要：通过对丹尼斯凤梨叶筒注入不同浓度的叶面肥,对其生理指标的影响进行研究,结果表明：凤梨最适宜的叶面肥浓度：小型苗期为0.4~1.0g/L;中型苗期为1.4~2.0g/L。在这两种浓度范围内对凤梨叶筒施肥,与对照组的普通施肥长势接近。A research on effect of different concentration of foliar fertilizer to physiological indicators of the Guzmania ＇Denise＇ was conducted.The results show that 0.4～1g/L in small seedling stage and 1.4～2g/L in medium seedling stage are the optimum concentration for foliar fertilization,the growth of the both concentration are similar to the control group with normal fertilization.
