The invention discloses a
paddy field shallow, wet and
dry water quantity
monitoring and control instrument, and belongs to the automatic
monitoring and control technology. A
soil water content positive pole detection probe, a negative pole detection probe and a
pyramid body are fixedly installed outside the lower end of a shell, an upper
water level positive pole detection probe and a lower
water level positive pole detection probe are installed in the shell in the mode of being capable of moving up and down to be adjusted, an inner cavity in the lower lateral portion of the shell and the exterior are of an communication structure, the
soil water content positive pole detection probe, the upper
water level positive pole detection probe, the lower water level positive pole detection probe and the negative pole detection probe are respectively communicated with a sensing
information processor through wires, and the sensing
information processor is sequentially connected with an electronic
valve opening-closing
automatic controller and an electronic
automatic control water valve through wires. The
paddy field shallow, wet and
dry water quantity
monitoring and control instrument provides the
technical support for popularization and application of the advanced
paddy field shallow, wet and dry alternate circulation
irrigation agriculture technology for north cold region paddy planting, and has the advantages of being novel and reasonable in structural design, high in
automation degree, high in measuring and control accuracy, reliable in use and few in fault.
