摘要：

本试验以喜林芋越冬中叶片变黄绿，观赏价值降低为背景，研究叶面喷施氮肥对新生叶片生长以及观赏叶片叶绿素含量变化，电导率变化情况。实验设置 N1 0.06%，N2 0.12%，N3 0.18%，N4 0.24%4个浓度处理，1个对照，三次重复。结果表明，N2和N3处理对叶片长宽度增加显著，叶绿素含量增加，观赏价值最佳，N2处理电导率低于对照，N3高于对照。结果表明，0.12%和0.18%浓度的氮肥叶面喷施对提高喜林芋观赏价值和商品价值具有良好的作用。

Abstract:

In this study, Philodendron andreanum leaves become yellow and green in winter, Ornamental Value reduced as background, Study of foliar fertilizer of nitrogen fertilizer on the growth of new leaves and Ornamental leaves changes in leaf chlorophyll content and Electrolyte leakage. Experimental set N1 0.06%, N2 0.12%, N3 0.18%, N4 0.24% four different concentrations treatment, a comparison, three times repeated. The results show that, N2 and N3 treatment on leaf length and width increased significantly, chlorophyll content increased, Ornamental value of the best, N2 conductivity lower than the control treatment, N3 is higher than the comparison. The results showed that 0.12% and 0.18% concentration of foliar fertilizer of nitrogen fertilizer in improving Philodendron andreanum ornamental value and commodity value has a good effect.
