Highland barley moisture efficient utilization system and control method

The invention provides a highland barley moisture efficient utilization system and a control method.The system comprises a control device, an irrigation device, an optical fiber deformation sensor and a moisture detection and utilization device, the moisture detection and utilization device comprises a water collection tank parallel to highland barley in the adjacent row, and a detection unit is arranged in the water collection tank and comprises a supporting block, a telescopic rod and a sponge block; the telescopic rod is arranged between the groove bottom and the supporting block, the sponge block is fixed to the upper surface of the supporting block, and an optical fiber in the optical fiber deformation sensor penetrates through the supporting block. During pouring, the sponge block absorbs water, the supporting block moves downwards, the optical fiber section in the supporting block deforms, and the optical fiber deformation sensor sends detected optical fiber deformation to the control device; the contr
