Abstract:: In order to make the Cymbidium sinense flowers open in the scheduled time，achieve the goal of ink orchid phase regulation.The Cymbidium sinense were used to study the effect of the different concentrations of plant growth regulator such as GA3 and NAA that adopt the method of spraying and injection on the ink orchid flower.The results indicated that gibberellin made flowering early and improved the quality of flower，spraying treatment method was better than injecting treatment.The effect of treatments with GA3 50 mg?L-1 was the most obvious.The treated plants abloomed earlier seven days and had higher flower stalk than that of CK，but it had no influence on the flowers stems and the spacing of flowers.A-naphthalene acid made flowering later and inhibited the growth of flower stalk，floret defeated seriously and the effect was prominent when the concentration was higher.The results also showed that injecting treatment made for flower stalk tidily and flower would blossom in a short period together，but on the contrary praying treatment made for flowers tidily and flowering more scattered.The study conclusions provided theoretical and practical basis for controlling the flowering time，regulating the marketing time and enhancing the ornamental effects，as well as increasing the income of the farmers who produced the flowers concentrately.
