S5: Positioning data information query: By logging into the user terminal, the positioning and data code information of each planting pit, plant, applied fertilizer and pesticide can be queried and called, so that management personnel can query the progress of agricultural and forestry operations and conduct asset and material management at any time through the user terminal.
