碩士 === 中興大學 === 園藝學系所 === 95 === This study aims to observe the effect on supplying different concentrations of calcium and phosphorous fertilizers and nitrogen ratio fertilizers on flower growth and postharvest quality of Anthurium andraeanum `Tropical’. The results of this study suggest that supplying 90ppm calcium fertilize has the best growth rate of leaf area and the most total soluble sugar(TSS) content of cut flower. On the nitrogen experiment, supplying NH4+:NO3-＝1:6 nitrogen fertilizer has the best growth rate of leaf area; supplying NH4+:NO3-＝1:4 nitrogen fertilizer has the most TSS content. Although supplying 90ppm calcium fertilizer and NH4+/NO3-＝1/6 nitrogen fertilizer have the best growth rate of leaf area, both of them have poor growth rate of flower. According to these results, higher growth rate of leaf area causes lower growth rate of flower. On the phosphorus experiment，phosphorus deficiency causes the decrease of phosphorus content of root, root activity, and fresh weight of flower。Among these three experiments, each of them cannot promote the calcium content in lobe and the vase life.
