AI Technical Summary
Existing fertilization devices cannot reasonably adjust the amount of nitrogen and the depth of fertilization according to the height of the tobacco field ridges, resulting in serious fertilizer loss and failure to effectively flow into the soil layer where tobacco plant roots grow densely, affecting tobacco yield and quality.
A fertilization control system was designed, including a depth detector, a speed sensor, a fertilization control device, a fertilizer sensor, and a motor stall sensor. The main control unit automatically adjusts the fertilization depth and amount, and combined with the fertilization lifting device and the ridging device, it achieves precise fertilization.
It enables automatic adjustment of nitrogen application rate and fertilization depth based on the height of the tobacco field ridges, allowing fertilizer to effectively flow into the soil layer where tobacco roots grow densely, improving fertilization efficiency, and has an intelligent early warning function to reduce fertilizer waste.
