Biogas slurry water-fertilizer integrated intelligent controls irrigation system and its application method

The invention discloses a kind of biogas slurry water-fertilizer integrated intelligent to control irrigation system, including several soil moisture content monitoring systems, biogas slurry pond, cistern, fertilizer compounding device, three-level irrigation pipe network, pumping system, magnetic valve, end pipeline is evenly distributed on the region of corresponding soil moisture content monitoring system control, the pumping system is by biogas slurry pump, water pump and pump control cabinet composition, process chip collects the signal of multiple probe moisture transducers and processing, the pump control cabinet receives and handles the signal of process chip, and control the keying of biogas slurry pump and water pump, the process chip controls magnetic valve.Also disclose the application method of above-mentioned irrigation system.The present invention uses soil moisture content monitoring system, and facility plastic greenhouse is monitored in real time, and sends instruction and irrigated automatically.Save manually, alleviate labor intensity, crop can be kept to compensate for the uncertainty of artificial irrigation amount to the demand of soil moisture content, improve irrigation quality and efficiency constantly.
