Abstract: The use of satellite remote sensing and ground monitoring accurate determination of SPAD value, combined with expert system, the growing of barley, the incidence of pests and diseases, yield and quality are diagnosed, and then the barley variable fertilization spraying and other agricultural technical measures are carried out. Key link of this technology is that the monitoring of satellite remote sensing image data picture, correspondence relation model between the ground monitoring SPAD value and growth health of barley. The implementation of this technology is of great significance in guiding farmer's scientific fertilization, stabilizing barley quality, increasing production, reducing preceding phytotoxicity and preventing the lodging.
