摘 要：
Effects of different concentrations of gibberellic acid solution on the fruit setting rate,single fruit weight,coloring and yield per unit area of Cangzhou Jinsi jujube jujube trees were studied. Results showed that when the flowering of jujube trees in Cangzhou Jinsi reached about 30%,spraying 12 mg/kg gibberellic acid solution could significantly improve the fruit setting rate,single fruit weight,coloring and unit area yield of Cangzhou Jinsi jujube trees.
