The invention discloses a fruit culture method adopting a double-layer paper sheathing bag. The method comprises the following steps that a, an outer layer paper bag and an inner paper bag are adopted for forming the double-layer paper sheathing bag, wherein the inner layer paper bag is made of white wax paper, the lower part of the inner layer paper bag is provided with a bonding region, after fruiting on fruit trees, the double-layer paper sheathing bag is sheathed on each young fruit, in addition, the upper part of the double-layer paper sheathing bag is folded for curling the double-layer paper sheathing bag, and then, a winding wire is used for simultaneously binding the inner layer paper bag and the outer layer paper bag onto the fruit stem of the young fruit; b, after the fruit grows to the coloring period, the binding wire on the outer layer paper bag is untied, the outer layer paper bag is removed, and the inner layer paper bag is remained for protecting the fruit coloring; c, after the fruit rapes, the inner layer paper bag is picked and sold along with the ripen fruit. The fruit culture method provided by the invention mainly solves the following two technical problems including the falling or edge folding problem as the inner layer paper bag is easily influenced by climates in the fruit coloring period in the prior art and the problem of difficulty in fruit re-packaging through a measure that the inner layer paper bag is with the fruit when the fruit is colored, picked and sold.
