The invention discloses an orchard soil clustering system and method. The system comprises a data acquisition node, a data transmission gateway, a data storage module, a data processing module and a modeling clustering module which are connected in sequence, the data acquisition node comprises a power supply module, and a processor, a sensor and a communication module which are electrically connected with the power supply module respectively; the processor is connected with the sensor and the communication module. The communication module sends the data to the data storage module through the data transmission gateway; the data processing module is used for preprocessing the data stored by the data storage module; and the modeling clustering module is used for carrying out modeling and clustering on the preprocessed data according to K-means clustering in a machine learning algorithm. According to the system, orchard soil types can be clustered, a user can clearly know the soil types, orchard block management is facilitated, the efficiency of an orchard irrigation system can be effectively improved, and therefore different irrigation methods are adopted for different kinds of soil.
