摘要： A water stress detection method for tomatoes in a seedling stage based on micro-CT and polarization-hyperspectral imaging multi-feature fusion, comprising: using micro-CT to scan microscopic morphological features such as water stress stomata, spongy body, palisade tissue, cilia, vascular bundle, root volume, main root, and root hair density of tomatoes; using a polarization-hyperspectral imaging system to obtain macroscopic morphological features such as crown width, plant height, and leaf inclination of water stress plants, as well as leaf vein distribution, average gray, and leaf margin shaded area under a water-sensitive wavelength of 1450 nm, and macroscopic morphological features such as polarization states, stock vectors, and Mueller matrix variables of 1450 nm feature images at 0°, 45°, 90°, 135°, and 180° feature polarization angles. By fusion of internal and external structures, above-ground, underground, and macroscopic and microscopic morphological features of water stress tomatoes, and mutual fusion of water stress feature wavelength images and polarization state features, advantages are complementary, comprehensive and precise extraction and precise quantitative analysis of water stress features of the tomatoes are implemented, and a basis for scientific management of water and fertilizer integration of facilities is provided.

摘要： A multi-scale habitat information-based method and device for detecting and controlling water and fertilizer for crops in seedling stage: performing fusion analysis on multi-scale features of the water and fertilizer stress of crops on the basis of crop canopy-scale three-dimensional laser scanning information, foliage-scale polarization-hyperspectral imaging information, and micro-scale micro-CT scanning information; combining the real-time feedback of the temperature, humidity, illumination and substrate moisture content within a crop growing greenhouse; by means of multi-information fusion modeling, comprehensively determining and feeding back the water and fertilizer stress of the crops as well as water requirement and fertilizer requirement information, and providing policy information for the amount of fertilization and irrigation. On the basis of the policy information for water and fertilizer, and on the basis of frequency conversion speed control technology and pipeline constant pressure control technology, a water and fertilizer control system controls the pressure of a pipeline and the flow rate of the fertilizer by means of dynamically controlling the rotation speed of an irrigation pump and a fertilizer pump, and thus, combined with the dynamic feedback of an EC value, the accurate control of a liquid fertilizer ratio and irrigation volume is achieved.
