Mobile trolley used for measuring soil sample data, configuring ratio of liquid fertilizer to water, and fertilizing

The invention discloses a mobile trolley used for measuring soil sample data, configuring ratio of a liquid fertilizer to water, and fertilizing. The mobile trolley is composed of a driving trolley, aprobe, a soil sampler, a sensing detection integrated module, a central processing unit, a water tank, a liquid fertilizer mother liquor tank, a fertilizer and water mixing tank, first valves, a second valve, a third valve, soil water outlet holes, a leaf surface spraying device, a stirring device, and a water inlet. The probe and the soil sampler detect soil data; the sensing detection integrated module transmits related data to the central processing unit; the central processing unit obtains the ratio of mother liquor to water through an algorithm; the water tank and the liquid fertilizer mother liquor tank automatically convey the fertilizer and the water to the fertilizer and water mixing tank; automatic stirring is conducted in the fertilizer and water mixing tank; and the prepared fertilizer is applied thro
