Abstract: In order to improve flower quality of Phalaenopsis, the effects of different fertilizers on growth and flower quality of Phalaenopsis ‘Sogo China Red’ and Phal. ‘Bull Demon King’ were investigated. The results showed that the characters of Phalaenopsis with T1 and T2 treatments were better than CK, but the influence of flower quality between T1 and CK was not significant. The nutrient solution of monomer fertilizer(N∶P∶K=1∶3∶2) showed a significantly impact on the leaf size, leaf chlorophyll content, flower stalk and the number of flower, and it was contributed to commercial value of Phalaenopsis .

Key words: Phalaenopsis, fertilizer, growth, flower quality

摘要： 以蝴蝶兰品种‘中国红’、‘牛魔王’为试材，研究不同肥料对蝴蝶兰生长及开花品质的影响。结果表明，T1(花无缺10-30-20肥)、T2(单体肥营养液N∶P∶K=1∶3∶2)处理的蝴蝶兰性状指标优于CK，但T1与CK对花的观赏性影响差异不显著；T2处理对蝴蝶兰叶的大小、叶绿素含量影响显著，花箭长、花朵数量均显著提高，更有助于提高蝴蝶兰的商业价值。
