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.
