The invention belongs to the field of garden planting, and particularly relates to a device for increasing garden transplanted nursery stock survival rate. The device comprises four floating mechanisms, a sunshade net and four vertical rod mechanisms, the floating mechanisms are mounted at four corners of the sunshade net and matched with the four vertical rod mechanisms distributed on the periphery of a nursery stock, at most two operators need to participate in mounting in the whole mounting process of the sunshade net, labor costs and mounting amount are greatly reduced, mounting efficiencyis higher, climbing devices such as scaffolds or lifters are omitted in the mounting process of the sunshade net, and potential hazards of the climbing scaffolds or lifters are avoided when preparation workload is decreased before the sunshade net is mounted.
