Conventional seeding monitors often exhibit diminished accuracy under challenging field conditions. To address this, this study introduces a novel monitoring system leveraging flexible pressure sensors integrated with a finger-clamp seed metering device. The core principle is that the passage of each seed-clamping finger over the seed outlet generates a distinct, continuous pressure signal profile. A sophisticated Signal Feature Identification Algorithm (SFIA) was developed that transforms this raw signal data into a one-dimensional image for analysis. By employing binarization and bilateral filtering, the SFIA effectively suppresses noise from field vibrations and extracts key topographical features, enabling precise quantification of seeding events through peak detection. The complete system, implemented using LabVIEW and Python, was rigorously evaluated in field trials. Under conventional tillage, the system achieved an overall monitoring accuracy of 96.55%, with reseeding and missed seeding detection accuracies of 98.96% and 98.55%, respectively. Critically, it maintained high performance in challenging no-till conditions, demonstrating 95.46% overall accuracy, with 98.35% for reseeding and 98.42% for missed seeding detection. This research validates a pressure-based sensing approach as a robust alternative to traditional methods, presenting a new technological pathway for developing high-precision seeding monitoring systems resilient to common agricultural interferences.

In light of the shortcomings in soil compaction observed in ridge cultivation following seeding in Northeast China, it was deemed necessary to develop a solution that would address the issue of soil moisture conservation and temperature control on the seedbed. The slide vibrational compaction device (SVPD), which is capable of compacting the upper and lateral soil of the ridge, was thus designed. The device features adjustable parameters, including an upper compacting plate inlet width of 260-360 mm, an outlet width of 230-290 mm, and a side compacting plate width of 140-240 mm. Its key components include an eccentric block generating vibratory force, a spring system with adjustable stiffness for controlled compaction, and compacting plates designed for uniform soil coverage. The optimal working parameters were determined to be an eccentric block angle of 36.00°, spring stiffness of 46.00 N/mm, and an upper plate exit width of 284.00 mm. The device achieves soil bulk densities of 1.206 g/cm³ on the ridge and 1.148 g/cm³ on the ridge side, significantly improving compaction compared to traditional methods, and increasing maize yield by 5%. Therefore, in order to meet the agronomic requirements of soil bulk density for crop growth on the ridge, the sliding vibration compacting device also achieves effective compaction of the soil on the ridge side, providing effective technical support for crop emergence and growth under the monoculture planting pattern in Northeastern China.
