Abstract:

Effect of N and K fertilization on one small inflorescences growth and suitable fertilizer formula of N and K nutrients ratio for the flower were carried out through pot experiment. Our results showed that the appropriate nitrogen amoun is beneficial to height, first branch lengh, flower numbers, dry weight of Dendranthema morifolium (Ramat.) Tzvel. Increasing potassium amount apply is helpful to flower numbers and dry weight. The high amount of potassium amount and the low amount of nitrogen amoun could make early flowering. Regarding lengh of first branch, plant height and dry weight as the target, it was showed that the recommended fertilizer amount of N and K2O for pot application for the small inflorescence was 0.47 and 0.40 g?kg-1 (each pot filled with 10 kg substrate).
