[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2The utility model provides a technical solution: a matrix blueberry irrigation system based on real-time weight, comprising a mechanical support 1 and an irrigation device, wherein a fixing ring 2 is arranged at the top of the mechanical support 1, a hook 4 is arranged at the lower side of the fixing ring 2, a weight detection unit is arranged between the hook 4 and the fixing ring 2, and the weight monitoring unit uses the Modbus-RTU communication protocol and the data analysis and processing unit to complete data transmission; the weight detection unit comprises a tension sensor 3 arranged between the hook 4 and the fixing ring 2, preferably an S-type tension sensor, a pull rope 5 is hung on the hook 4, and a blueberry potted plant 6 is suspended at the bottom end of the pull rope 5, and the real-time weight of the blueberry potted plant 6 is monitored by the weight detection unit, thereby obtaining a direct phenotypic indicator of the overall growth level of blueberries.

[0017] A tipping bucket rain sensor with a diameter of D=200 mm is used instead of a conventional liquid volume sensor to measure the fertilizer liquid discharged in the form of drips. The measured liquid volume unit is converted from mm to mL using (π*R*R*H) / 1000, where H is the data measured by the rain sensor and R is the radius, which is numerically equal to D / 2.
