Abstract
In view of increasing demands of high quality and safe agricultural products, it is important to effectively and precisely manage crop production. Precision agriculture is a site-specific cultivation method, and has been developed by using satellite remote sensing for field crops. However, more and more crops such as vegetables and ornamental plants are grown in greenhouses, and growth status monitoring of these crops is equally important as that for field-grown crops. Consequently, a ground-based remote sensing system for greenhouse precision cultivation needs to be developed. This work aimed to develop a RFID-integrated precision cultivation system based on remote spectral imaging of crops and environmental sensing for greenhouse production. This work illustrated the precision cultivation approach using vegetable seedlings as an example. Groundbased multi-spectral imaging system with plant-oriented sensing algorithm was developed in this study. A mobile environmental sensing system, including temperature, relative humidity and light intensity, was also developed to measure and analyze the spatial distribution of these environmental parameters in the greenhouse. The data and information communication was conducted through a wireless network. Irrigation policies corresponding to PLAI (Projected Leaf Area Index), NDVI (Normalized Difference Vegetation Index) and environmental conditions were established to provide a basis for precision irrigation. A variable rate spraying system was developed to implement the precision irrigation practices based on the analyzed status. This research successfully integrated RFID (Radio Frequency Identification), environment sensing, and remote spectral imaging for developing precision cultivation and traceability systems for the greenhouse production. ?
