The invention discloses a method for preparing mature bee products by using bee. The method comprises the following steps that: an area isolated from the outside is enclosed by a separation net, and bees cannot pass the separation net via meshes of the separation net; and the bees are raised in the area in the common way, and the boxes storing immature honey are arranged inside/outside the beehives. In order to ensure the honey-making effect, the boxes storing the immature honey can be honey-storing cans and honey-storing tubes, pressure pumps and control valves are arranged on the pipelines,by which the honey-storing cans and honey-storing tubes are communicated, and the tube walls of the honey-storing tubes are provided with a plurality of honey-discharging holes. The method has the advantages that: by adopting simple facilities and using natural quality of bees, the immature honey is processed into the natural high-concentration honey, the investment on concentrating equipment is saved, and the natural quality of the finished product of honey is improved. Because no mechanical equipment or other human factors are involved in the whole processing flow, the finished product of honey prepared by the method passes the whole natural processing flow, and the product quality is guaranteed.
