Fuente: Wipo "BigData" The invention provides a big data analysis application system suitable for agricultural informatization, the big data analysis application system comprises a cloud server and a plurality of local data servers, one local data server is responsible for information acquisition and primary processing of a crop, and the cloud server comprises a data analysis module and a guidance application module. And the data analysis module receives the sensor data from each local data server, analyzes the cause of abnormal growth of the crops according to the sensor data, and guides the application module to give corresponding suggestions for planting operation according to the cause of abnormal growth of the crops. According to the invention, the storage and uploading of the sensor data are controlled based on the growth guidance parameters of the crops, the amount of data involved in processing is greatly reduced under the condition that the monitoring accuracy is ensured, the reasons of abnormal growth of the crops are analyzed from multiple angles, and the actual agricultural production is guided more comprehensively and effectively.
