The invention discloses an adjustable micro-droplet generation device, comprising a mounting frame equipped with a droplet extrusion mechanism, a speed control mechanism and a loading platform. The nozzle of the droplet extrusion mechanism is directly above the loading platform and located at the outlet end of a hollow glass tube serving as an air flow channel in the speed control mechanism. The device controls the droplet diameter and single-droplet quantity through the extrusion mechanism, and adjusts the falling speed of droplets via the speed control mechanism. The device can generate single or multiple pesticide droplets with controllable diameter and falling speed, which is widely applicable to researching the influence of droplet velocity and size on plant surface spreading, pesticide performance testing, and collision and fusion of multiple droplets. It provides a theoretical basis for reducing pesticide dosage and residues, with broad application prospects.
