灌浆期小麦倒伏后光谱变化特征
Spectral Variation Characteristics of Wheat Lodging in the Filling Period
摘要
Abstract
[ Objective ] The research aimed to study the spectral variation characteristics of wheat lodging in the filling period. [ Method ] By artificially simulating the wheat lodging phenomenon in the filling period, measuring the spectral reflectivity of lodging wheat with the spectrometer,the variation reason and characteristics of canopy spectrum were analyzed. [ Result] The more serious the wheat lodging was, the more obvious the plant spectrum variation characteristic was. The canopy spectral reflectivity of lodging wheat increased, and the refiectivity of 5 -level lodging wheat in the prior and middle periods of filling near the infrared band was the highest. As the time passed, the canopy spectral reflectivity of wheat which grew normally and lodged had the same variation. [ Conclusion ] The research provided the theory basis for using the remote sensing image to monitor the objective zone, gain the lodging area and the affected degree.关键词
