The invention discloses a drying rack for agriculture. The drying rack for agriculture comprises a supporting base; a storage battery is fixedly connected with the middle end of the bottom of an inner cavity of the supporting base; a first motor, a supporting rod and a second motor are sequentially and fixedly connected to the top end of the supporting base from left to right; an output shaft of the first motor and an output shaft of the second motor are both fixedly connected with a rotating disk; the upper ends of the left and right sides of the outer surface of the supporting rod are each fixedly connected with a connecting plate; and the sides, away from the supporting rod, of the connection plates are movably connected with a first drying plate and a second drying plate correspondingly through movable joints. According to the drying rack for agriculture, due to the effects of the first motor, the rotating disk, a pulling rope, a second guiding roller, a first guiding roller, a pulling ring, the first drying plate, the second motor, a third guiding roller, a fourth guiding roller, the second drying plate, a hinge and a spring, the drying rack can have the extending and shrinking capacity, and the problems that an existing drying rack for agriculture is huge in occupied area and is not convenient for people to use are solved.
