Experimental Study on Measuring the Internal Porosity of Plant Canopy by Laser Distance Measuring

摘要

At present, crop pest control is mainly based on pesticide, but the effective utilization rate is low. This is because the plant grows to a certain period of time and will form a high canopy density of canopy. This phenomenon will lead to the attenuation of droplet deposition. The method of layering the canopy porosity of the plant was carried out, and the plant model with the shape of the canopy of the real plant and the internal structure was constructed, and stratified according to the needs, and the porosity was obtained by layer-by-layer test using the laser distance measuring module. The canopy projection map of the plant can be obtained by fitting the curve, which can effectively analyze the internal structure of the canopy of the plant and analyze the path of droplet deposition, which provides a reliable basis for the deposition of pesticides.
