PLANT INFORMATION ACQUISITION SYSTEM, PLANT INFORMATION ACQUISITION DEVICE, PLANT INFORMATION ACQUISITION METHOD, CROP MANAGEMENT SYSTEM, AND CROP MANAGEMENT METHOD

摘要

To provide a plant information acquisition system, a plant information acquisition device, a plant information acquisition method, a crop management system, and a crop management method, with which it is possible to acquire information on plants at low cost, as compared with a chlorophyll gauge or a spectroscopic analyzer, by acquiring information about a plant based on its surface color from image data in which the plant is image-captured, and which, in production of a crop of rice or the like, assists, via a smart phone, etc., as a user terminal, with fertilization management for determining a fertilizer amount, etc., and manuring management that includes other farm work on the basis of observed data on equivalent leaf color value, etc., calculated from image data in which a crop is photographed.SOLUTION: A camera 30 is connected to a smart phone 1. It is possible to obtain an equivalent leaf color value from image data obtained by photographing the leaves of a rice plant with the camera 30. By transmitting this equivalent leaf color value to a management server 10, information about a necessary fertilizer amount, for example, when the equivalent leaf color value is smaller than a standard can be obtained as management information for fertilization management.SELECTED DRAWING: Figure 9
