Embodiment
[0059] The remote sensing inversion method of starch content in the aboveground part of rice based on the Lars regression algorithm of cross-validation in this embodiment is based on the measured hyperspectral data, and adopts the rice planting area (the rice and wheat planting base in Huai'an, Huai'an Academy of Agricultural Sciences, Jiangsu Province, rice variety The rice canopy reflectance spectral data and the starch content data of the aboveground rice collected for Huaidao No. 5, and the sampling period is the jointing stage of rice. There are a total of 48 sampling points. These sampling points are evenly distributed and completely cover the entire rice planting area. The data of 48 sampling points are randomly divided into two parts, of which the data of 36 sampling points are used for model building, and the data of 12 sampling points are used for model testing. The workflow of the remote sensing inversion method for starch content in the aboveground part of rice base...
