Abstract：In this experiment, spraying three different concentrations of potassium dihydrogen phosphate (KH2PO4)on the seedling of “Silver drag” Cymbidium, its growth and development had been investigated. The morphological characteristics, content of chlorophyll and soluble sugar were measured after the “Silver drag”Cymbidium had been spraied with solution of KH2PO4 (0.1% , 0.3% and 0.6% , respectively) for 15 days. Compared with the control group (0% KH2PO4), the leaf’s length and width of “Silver drag”Cymbidium, and the flower arrow’s length have been significantly increased by 1.67 cm when sprayed 0.1% and 0.3% KH2PO4. Spraying 0.1%-0.6% KH2PO4 can obviously accelerate thd flowering of “Silver drag” Cymbidium. Spraying 0.1% KH2PO4 may significantly increase the content of the chlorophyll while 0.3% KH2PO4 can significantly increase the content of soluble sugar than other treatment.
