A fruit tree pollination protective screen comprises weft wires 2 and warp wires 1, and is characterized in that the weft wires penetrate two coils chained by warp wires, the weft wires are clamped and obliquely chained on the trunk lines of two warp wire coils, every ten rows of weft wires are interwove in a manner of two holes for one string, and the wire diameter of weft wires and warp wires made of plastic filaments is 0.20 to 0.22 mm. The fruit tree pollination protective screen in the chaining structure also has the characteristics that the coverage rate of the mesh is less than 15 percent; the light transmittance of the protective screen is greater than 85 percent; and a gram weight per square meter is less than 50g. The entire tree crown is covered by the protective screen, so thatthe normal growth of fruit trees can not be influenced, and the standard aberration caused by pollination of poor varieties such as honeybees and butterflies also can be avoided; and the honeybees are cultivated in the protective screen to deflower and pollinate, thereby maintaining the purity of variety and achieving quality assurance and income increase.
