Abstract: In view of problems that the first pressurization system in water-fertilizer integration technology was usually built in a pump room，which was bulky，high in investment cost and difficult to change movement，a mobile fertilization irrigation that could realize mobile and remote control was designed.The system used a combination of a car and a fertilizing irrigation device to place a water-fertilizer integrated device and a remote controller on a car chassis to realize mobile irrigation and fertilization on a small area of farmland.Remote controller could control switching of gasoline pump and fertilizer tank operation and irrigation area selection function.Experiments showed that the system was small，economical and durable，able to accurately move to desired irrigation area，and to achieve manual or remote control of water and fertilizer irrigation.
