The invention discloses a smart agricultural variable fertilization control system and method based on image recognition, and relates to the technical field of smart agriculture, and the method comprises the steps: collecting an orchard multi-source image and laser radar data through an unmanned aerial vehicle, and dividing an orchard into different microclimate management units according to topographic features; extracting the vein mesophyll color difference ratio of the citrus leaves from the visible light image, correcting the traditional spectral index, and eliminating the interference of light environment difference on nutrition diagnosis; based on the corrected spectral index, establishing a nitrogen demand model in combination with terrain and tree body parameters, and generating a single-plant personalized variable fertilization prescription map; and importing the prescription map into the intelligent fertilizer applicator, and controlling fertilizer discharge to execute variable-rate fertilizer application operation by locating and inquiring the fertilizer application amount in real time. According to the method, the dynamic compensation model based on the vein and mesophyll color difference ratio is constructed, the leaf morphological characteristics and the spectral information are cooperatively processed, the traditional vegetation index is dynamically corrected, and the spectral response deviation caused by the light environment difference under the complex terrain can be reduced.

The utility model relates to solar panel fixing technical field especially solar power generation panel fixing device, its technical scheme includes: the bracket is installed with photovoltaic board, the photovoltaic board is covered on the bracket through the pressure block, the bottom end surface of bracket is equipped with support rod and guide sleeve, the bottom end of bracket is equipped with locking mechanism through guide sleeve, the pressure block end is locked after the penetration through the bracket through locking mechanism. The utility model through the screw rod and the bolt, the screw cooperation of second movable rod, rotates screw rod can drive first movable rod and second movable rod and its plug -in rod synchronous insertion bolt through -hole, forms the fastening of many directions to pressure block, cooperation magnet adsorption between first movable rod and second plug -in rod, realize first movable rod and second movable rod collaborative action, simplify operation process, orderly unlocking mode avoids component collision damage, significantly promotes the stability and dismounting efficiency of solar power generation panel fixed.
