The backpack type precise positioning fertilization system according to claim 2 is characterized in that: The dosing device comprises: a dosing device left shell, a dosing device right shell and a dosing slide plate; The dosing device left shell and the dosing device right shell are hingedly connected; the dosing slide plate is installed on the dosing device right shell; the dosing slide plate can slide to different positions in the dosing device right shell to form different volumes with the dosing device left shell.

5. The shoulder-type precise positioning fertilization system according to claim 4 is characterized in that: The backpack quantitative fertilizer applicator also includes: a weighing sensor; The weighing sensor is connected and installed on the dosing device; wherein the weighing sensor is a resistance strain sensor.

6. The backpack type precise positioning fertilization system according to claim 1, characterized in that: The user terminal is a mobile phone user terminal and / or a PC user terminal.

7. A positioning method for the backpack type precise positioning fertilization system according to any one of claims 1 to 6, characterized in that: It includes the following steps: Step S1: System startup: before the fertilization operation, the backpack precise positioning fertilization system is started, so that the Beidou / GPS receiving base station, the Beidou / GPS receiving mobile station, the quantitative fertilizer applicator, the server or the user terminal are started, and the Beidou / GPS receiving base station, the Beidou / GPS receiving mobile station and the Beidou / GPS satellite navigation and positioning system are kept in mutual communication state; Step S2: Scanning and positioning the fertilizer: align the scanning module on the quantitative device with the data code on the fertilizer bag, press the trigger switch to scan the data code on the fertilizer bag, and the control module reads the data code information on a bag of fertilizer bag and the positioning data information corresponding to the Beidou / GPS mobile station and the bag of fertilizer respectively; Step S3: Fertilizer code scanning and location data information storage: the control module of the quantitative device issues an instruction to control the mobile communication module to transmit the read fertilizer packaging bag data code information and the location data information of the Beidou / GPS mobile station located in the bag of fertilizer to the server for storage; Step S4: Fertilization quantitative application: the fertilizer scanned in S3 is put into the fertilizer bag, and the fertilizer in the fertilizer bag is filled into the quantitative device through the feeding pipe, and the fertilizer quantitative application is completed according to the volume set by the quantitative device; Step S5: quantitative fertilization: align the quantitative device above the fertilization pit, open the quantitative device so that the fertilizer in the quantitative device falls completely into the fertilization pit; Step S6: Fertilization positioning information generation: while the quantitative fertilizer applicator is applying fertilizer to the fertilizer pit, the control module reads the high-precision fertilization positioning data information of the Beidou / GPS receiving mobile station located at the fertilizer pit and after the error is corrected by the Beidou / GPS receiving reference station; Step S7: Storage and query of fertilizer positioning data information: The control module of the quantitative fertilizer applicator issues an instruction to control the mobile communication module to transmit the high-precision fertilizer positioning data information of the Beidou / GPS receiving mobile station located in the fertilizer pit to the server for one-to-one storage. The high-precision fertilizer positioning of each fertilizer pit and the data information corresponding to the fertilizer package scanned in S2 can be queried and called by the user terminal to log in to the server, so that the fertilizer management personnel can monitor and check whether the fertilizer operators are performing fixed-point precise fertilization as required.

8. The positioning method of the backpack type precise positioning fertilization system according to claim 7, Its characteristics are also: In S5, the fertilization operator applies the fertilizer in the dosing device into the fertilization pit, and at the same time, the control module issues an instruction to control the camera to take a real-time photo of the fertilization pit; In step S7, the fertilization positioning data information of the Beidou / GPS receiving mobile station read by the control module is temporarily stored in the control module in the area without communication signal, and the fertilization positioning data information of the quantitative fertilizer applicator is automatically uploaded and stored in the server when entering the area with communication signal.
