Special Issue Information

Dear Colleagues,

The function of planting equipment is to sow the seeds (seedlings) of crops evenly into a certain depth of seed ditch with a certain sowing amount or spacing, cover them with an appropriate amount of fine and moist soil, and fertilize and suppress them appropriately. Pesticides and herbicides can be sprayed to provide good growth conditions for plant growing, thereby achieving high and stable yields and improving production efficiency.

In recent years, crop cultivation has continuously developed towards a direction that prioritizes yield and efficiency, which puts higher technical requirements on planting equipment. Therefore, advanced precision planting technology and equipment, as an essential means to promote large-scale agricultural production, has become a focus and hotspot in the current field of planting equipment research.

This Special Issue highlights influential research and commentary, focusing on the recent advances in precision planting technology and equipment. This issue will comprehensively cover interdisciplinary and comprehensive research on critical technologies and methods for advanced crop cultivation (precision seed-metering device, efficient and low loss transplanter, seed guide device, profiling mechanism, soil covering and compaction device, intelligent planting equipment, etc.) and research reports on other advanced technology systems promoting crop cultivation and production (variable rate seeding (fertilizing) technology, etc.). In addition, we encourage researchers to conduct practical research based on the actual planting conditions (soil, terrain, paddy fields, etc.) in their respective regions and to adopt innovative technologies and measures to solve the technical difficulties in current planting equipment operations. This Special Issue invites all types of articles mentioned above, using qualitative, quantitative, or mixed methods, as well as empirical preliminary research and comments.

The process of hole seeding on the mulch during full-film double-row furrow corn planting faces issues such as poor seed discharge and seed blockage. To address these challenges, a pendulum-lever-type hole-forming mechanism is designed, along with an adjustment device. By analyzing the working principles of the pendulum-lever-type hole seeder and the adjustment device, the structural parameters of the device are determined. Through theoretical analysis and simulation experiments, three-dimensional models of seeds and hole seeders are constructed. Based on MBD-DEM cosimulation, the trajectory of seed movement and the seeding process of the hole seeder are analyzed to elucidate the effects of the hole-former opening and the number of pendulum bearings on seeding quality. To improve the operational performance of the hole seeder, experiments are conducted using the hole seeder’s rotating disc speed, lever angle of the hole-former, and the number of pendulum bearings as experimental factors, with the qualification index, miss-seeding index, and reseeding index as experimental indicators. A three-factor, three-level Box–Behnken central composite experiment is performed to obtain mathematical models of the relationships between the experimental factors and indicators. Using Design-Expert 12 software, the regression models are optimized for multiple objectives to obtain the optimal parameter combination: a seeder disc speed of 49 r/min (corresponding to a forward speed of 5.76 km/h), a lever angle of 131°, and four pendulum bearings. Under this optimal parameter combination, the qualification index is 91.70%, the miss-seeding index is 4.57%, and the reseeding index is 3.73%. Experimental validation of the seeding performance of the hole seeder under the optimal parameter combination is conducted. Bench tests show that the qualification index, miss-seeding index, and reseeding index are 90.53%, 5.60%, and 3.87%, respectively. Field tests demonstrate a qualification index of 89.13%, a miss-seeding index of 5.46%, and a reseeding index of 6.41%. The actual results are consistent with the optimized values, providing valuable insights for the design and performance optimization of hole seeders. Full article
