The invention discloses a Chinese date fruit maturation promoter. The promoter consists of the following raw materials in parts by mass: 5 to 6 parts of paclobutrazol, 7 to 9 parts of sodium borate, 2 to 5 parts of copper chloride, 5 to 8 parts of iron chloride, 4 to 8 parts of manganese chloride, 3 to 5 parts of zinc chloride and 1,000 parts of purified water. 10-time diluent of the promoter is sprayed onto fruits during a Chinese date fruit expansion period, after being sprayed for two times, the fruits are completely colored 20 days later, the maturing time of the fruits can be over 15 days earlier than that of a reference group, the fruit cracking rate is reduced by over 35 percent, the incidence rate of black spot is reduced by over 20 percent, and Vc, dissoluble sugar content and single fruit weight in the fruits are not obviously different from those in the reference group. The preparation is simple in the preparation method and the using method, Chinese date farmers can prepare the preparation, and th
