[0002] Crop spectral information refers to the obvious spectral reflectance characteristics of ground plants. Unlike soil, water and other typical landforms, the response of vegetation to electromagnetic waves is determined by its chemical and morphological characteristics, which are closely related to the development, health and growth conditions of vegetation. With the development of science and technology, crop cultivation technology has also developed to a higher level. In order to ensure the healthy growth of crops, crop spectral information will be regularly collected during large-scale crop cultivation to analyze the health of crops and make corresponding adjustments to crop cultivation plans.
