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

Abstract

The invention discloses an intelligent-control irrigating system integrating biogas slurry, water and fertilizer. The system comprises a plurality of soil moisture monitoring systems, a biogas slurry pond, a reservoir, a fertilizer mixing device, a three-stage irrigating pipe network, a pump system and solenoid valves, wherein tail end pipes are uniformly distributed in corresponding regions controlled by the soil moisture monitoring systems; the pump system comprises a biogas slurry pump, a water pump and a pump control box; a processing chip is used for collecting and processing signals of a plurality of probe moisture sensors, the pump control box is used for receiving and processing the signals of the processing chip and controlling the starting and stopping of the biogas slurry pump and the water pump, and the solenoid valves are controlled by the processing chip. The invention also discloses a use method of the irrigating system. The irrigating system adopts the soil moisture monitoring systems to monitor greenhouses in real time and gives instructions to perform irrigation automatically. Therefore, labor is saved, the labor intensity is reduced, the requirement of crops for the soil moisture can be maintained constantly, the defect of uncertainty of the manual irrigation amount is overcome, and the irrigating quality and efficiency are improved.

Description

technical field [0001] The invention relates to a biogas slurry water and fertilizer integrated intelligent control irrigation system and a use method thereof. Background technique [0002] In recent years, the pollution of livestock and poultry breeding has attracted widespread public attention and the governments at all levels have attached great importance to pollution control decisions. Benefits also produced a large number of by-products, namely biogas slurry. Biogas slurry is rich in elements such as nitrogen, phosphorus, and potassium. Direct discharge into the environment without subsequent treatment will have a serious impact on the self-purification function of surrounding water bodies. It has become a key problem to be solved in water environment protection and has long plagued the healthy development of animal husbandry. . [0003] Biogas slurry digestion in farmland is an ecological method to process and utilize biogas slurry through the joint action of farmla...

AI Technical Summary

Problems solved by technology

[0004] The traditional biogas slurry utilization method is limited by factors such as large amount of labor and high labor intensity, so that the excellent agricultural efficacy of biogas slurry is generally recognized, but it cannot be applied in a large area
