Abstract: At present, in the production of facility horticulture, the nutrient solution or pesticide configuration is mainly artificially mixed nutrient solution or pesticide in a larger pool. This method has a large area, low efficiency, high cost, time-consuming and labor-intensive, which seriously restricts our facilities. Agricultural development. Aiming at this problem, an intelligent integrated water, fertilizer and medicine equipment is designed. The equipment is mainly composed of main pump, peristaltic pump, ec and pH sensor. Fertilizer or medicine is prepared in the irrigation pipeline. It has high precision, saves time and effort, and is ready for use without a large pool. The overall structure, control system and human-computer interaction interface of the equipment are mainly designed. After verification tests, the flow accuracy of the main pump and the peristaltic pump are respectively 94.89% and 96.69%, the ec control error is 0.68%, and the pH control error is 1.42%.It has good application value.
