Abstract: The chemical picking method of Hippophae fruit is studied in this experiment which directed against some prominent problems existing in the process of Hippophae picking and used the proper concentration of ethephon that possesses the efficacy of impelling to fall the fruit and leaves. The experimental results showed that parts of the fruit began to fall after 7 days under the general climate if 40% of 10,00ppm ethephon solution was sprayed while Hippophae fruit changed colour from green to yellow. Compared with the manual picking method, the efficiency has been raised 8 times using this kind of technique, and the percentage of perfect fruit has increased clearly. If the chemical picking method combined with other vibrated or air-driven picking machineries, the effect will be much better.
