摘　　要：对凤梨叶筒注入不同浓度的叶面肥,研究其叶片的生长状况。结果表明:凤梨小型苗期最适宜的叶面肥浓度为NB肥0.4～1.0 g/L+MgSO40.5 g/L,中型苗期最适宜的叶面肥浓度为NB肥1.4～2.0 g/L+MgSO41.0 g/L。在此肥料浓度范围内对凤梨进行叶筒施肥,其长势与普通施肥的对照组长势接近。The effects of different concentrations of foliar fertilizer on the leaf growth of Aechmea fasciate were studied.The results showed that the optimum foliar fertilizer was as follow：0.4-1.0 g/L NB fertilization＋0.5 g/L MgSO4 at small seedling stage,and 1.4-2.0 g/L NB fertilization＋1.0 g/L MgSO4 at medium seedling stage.
