Water, fertilizer, air and heat precision irrigation control integrated machine

The invention discloses a water, fertilizer, air and heat precision irrigation control integrated machine which comprises a main water channel, a hot water channel, an air channel, a fertilizer channel, a detection circuit and a controller. Wherein the detection circuit is communicated with the solenoid valve of the liquid to he detected and the electrode fusion detection device, so as to realize on-line detection of the concentration of the mixed liquid fertilizer. The air channel mainly includes two parallel air channels of micro-nano bubble generator and ozone disinfection device. The ARM controller uses soft-sensing modeling of artificial intelligence technology to detect and control the concentration, EC and PH value of mixed solution on-line, and complete the intelligent control and management of water, fertilizer, air and heat. The invention has the advantages of reasonable design, good stability and reliability of equipment and high intelligent degree and improves irrigation efficiency.
