Abstract
In the process of field spraying, the migration and deposition of pesticide droplets in plant canopy are the key to ensure the high efficiency of application. This paper takes cotton as an example to study the spatial droplet deposition distribution based on the static porosity of cotton. The cotton canopy was regarded as porous medium from the point of droplet transportation in cotton canopy. Cotton canopy was divided into three layers and represented different cotton forms through the combination of different porosity. Set up a static porosity test device for cotton and conduct spray deposition test. At the same time, the spatial distribution of droplets under different porosity was obtained through CFD simulation. The results show that the static porosity droplet deposition test device can be used to analyze the spatial distribution of droplet deposition.
