AI Technical Summary

Technical Problem

The existing corn breeding and cultivation devices have different spraying ranges, angles, and atomization effects, resulting in uneven nutrient solution spraying, which affects the uneven growth and development of seedlings and reduces the accuracy of breeding.

Method used

A spraying device including a trapezoidal plate, a support, a tank, and a motor drive was designed. The nutrient solution flow is controlled by cylindrical and gear transmission to achieve precise and controllable irrigation. Combined with an observation component to monitor the remaining amount of nutrient solution, a uniform supply is ensured.

Benefits of technology

It enables precise and controllable irrigation of nutrient solution, reduces waste, ensures that seedlings receive stable water and nutrients, and improves the accuracy and efficiency of the breeding process.
