Currently,there is no water-fertilizer integration system on the market that is suitable for large-field irrigation and has high fertilizer mixing accuracy.In this paper,the bypass structure is designed to replace the main pipe with a static mixer,and the focus is on improving the uniformity of fertilizer mixing,and the fertilizer mixing components are op-timized and improved.Based on the basic principles of fluid mechanics and CFD,the number of mixing units and the length-to-diameter ratio of SK-type static mixer in the process of water and fertilizer mixing were analyzed by Fluent soft-ware to find out the best structural parameters of the mixer and to improve its structure,and the open trench static mixer was designed.
