An adaptive dwarfing and densification seeding regulation method and system for flat and depressed land environment
By setting up sensing devices and hardware frequency-modulated door lock channels on the seeder, the furrowing depth and seeding frequency can be dynamically adjusted, solving the problem of seed germination difficulties caused by soil changes in flat and low-lying areas, improving sowing quality and seedling emergence rate, and enhancing the reliability of the control system.

AI Technical Summary
Existing sowing techniques are ill-suited to adapting to changes in the local soil microenvironment in flat, low-lying areas prone to waterlogging, leading to difficulties in seed germination and insufficient precision and timeliness in control.
By setting up a sensing device at the front end of the trench to obtain the rheological damping response, a high-frequency rheological impedance envelope current is generated to adjust the trench depth and seeding frequency. Dynamic density seeding is achieved by using a hardware frequency-modulated door lock channel. Combined with a unique identity signature parameter verification mechanism, the reliability and robustness of the control system are ensured.
Stable seed germination was achieved in complex and variable soil environments, improving the emergence rate and reducing the response time of the control system and the impact of external interference, thus maintaining the expected number of seedlings within the target area.
