Abstract: Provided is a fruit tree screen having a structure preventing damage to protective sheets without using eyelets to connect the protective sheets to each other. When protective sheets (20) are connected to each other using a connecting member (40), since the protective sheets (20) are connected to each other by an elastic ring body (41), when the protective sheets (20) move due to wind or the like, the elastic ring body (41) absorbs impact while being elastically expanded and contracted, and thus damage to the protective sheets (20) can be effectively prevented without coupling other members, such as eyelets, to through-holes (22). Since eyelets and the like are not coupled to the protective sheets (20), manufacturing costs can be lowered, the volume of packages can be reduced, and it is possible to promptly respond to a client demand due to simplification of the manufacturing process.
