Chinese. 为促进月季旺盛生长，增加开花量，增大花径，延长花期，提高抗逆性和越冬抗寒能力，在植物生长期，于叶面分别喷施不同浓度的尿素、磷酸二氢钾、磷酸氢二氨及其组合的肥料，研究叶面追肥对藤本月季“安吉拉”生长和开花的影响。结果表明：生长期喷施氮、磷、钾肥料能促使“安吉拉”植株健壮生长，枝条粗壮，抗性增强，花繁色艳，花径大，花期长。其中，以3‰尿素＋5‰KH2PO4混合追肥的效果最为显著，株高76cm、花径6.2cm、单株开花量103朵和分枝数9枝均显著大于其他处理，且枝条风干率只有15%。

To improving the vigorous growth, the amount of blossom, the diameter of flower, blooming period and the stress resistance of Rosa Chinensis, the effects of foliage supplemental fertilizers such as urea, KH2PO4, (NH4) 2HPO4 and their combination on growth and florescence of climbing rose “Anjila” were studied during plant growing period. The results showed that plants with foliage supplemental nitrogen, phosphorus and kalium possessed better growth, stronger shoot, bigger flowers, richer colors, and longer blooming season than the control plants. The best formula of foliage spray was 3‰urea ＋ 5‰ KH2PO4, which plant height, flowers size, the flower amount per plant and branch number were significantly higher than the other controls, and its dry matter ratio was 15%.
