Circulating warm water spraying device and method for asparagus germination acceleration

The invention discloses a circulating warm water spraying device for asparagus germination acceleration and a method thereof, and belongs to the technical field of asparagus planting. A circulating warm water spraying device for asparagus germination acceleration comprises a device shell, a water collecting tank is installed on the lower portion in the device shell, and a backflow tank is installed below the water collecting tank; a water storage tank is mounted on one side of the mounting frame; and a water guide pipe is arranged in the movable spraying pipe, and a telescopic plate is mounted in the mounting box. The problems that in the actual use process of the germination accelerating device, water is seriously wasted due to spraying, uniform spraying cannot be achieved, and the germination accelerating effect is affected are solved, water is recycled through a water collecting box and a backflow box so that follow-up circulating work can be facilitated, in the spraying work, water can be guided out throu
