Paddy field shallow, wet and dry water quantity monitoring and control instrument

Abstract

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.

Description

technical field [0001] The invention belongs to the automatic monitoring and control technology, and mainly relates to the automatic monitoring equipment for the water level, soil dryness and humidity in the rice field during the rice planting and growth process. Background technique [0002] The "shallow", "wet" and "dry" alternating cycle irrigation technology for rice planting is a new rice irrigation technology promoted and applied to the whole province in September 2010 by the Water Resources Department of Heilongjiang Province and the Heilongjiang Provincial Rice Irrigation Experimental Center. Biochemical effects are affected by genetic characteristics and growth hormones, and a certain degree of water stress is actively applied at certain stages of its growth and development to exert its own regulatory function and adaptability, causing the redistribution of assimilates among different organs, reducing the The growth is redundant, the quality of rice is improved, and...
