Application and Prospect of Spectroscopy Technique for Agriculture

Spectroscopy technique, for its advantages of convenience, celerity, high precision and non-destroy measure, plays an importanl role in precision agriculture, and has become an important instrument to obtain farmland environmental information. From the angles of soil spectroscopy characteristics, foliage spectroscopy characteristics and canopy spectroscopy characteristics, the appli cation of spectroscopy technique are summarized, such as soil quality measuring, diagnosis of crop water and nutrition, estimating the yield, seed quality inspecting, insect pests and pesticide remnant inspecting and so on. The problems, such as low spectroscopy differentiate rate, incomplete models, half-baked system and skimble-scamble applied yardstick, are analyzed in the paper, and also the applied prospero is discussed.
