An automatic soil testing and formulated fertilization device for orchards

The invention provides an automatic soil testing and formulated fertilization device for orchards, and relates to the technical field of agricultural machines. The device includes a moveable rack. Themovable rack is provided with a longitudinal feed mechanism. A detection outer box is disposed on two longitudinal mobile tables. One side of the detection outer box is provided with a transverse feed sampling mechanism. A soil substance concentration detection module is disposed on the detection outer box. Through a design of wind ports, wind tunnels and a fan, light soil in a soil sample is blew into a reagent bottle, thus saving time for grinding. The reagent bottle is moved by utilizing a reagent bottle lifting and extruding mechanism. Ingenious mechanism cooperation is achieved by meansof a baffle plate and a lapping plate. Soil detection is achieved by utilizing the soil substance concentration detection module. Fertilization control is achieved by utilizing blanking wheels finally. The device is ingenious
