Special Issue Information

Dear Colleagues,

For man, machine has become the development trend of modern agriculture. Unlike tillage and plant protection, planting and harvesting vary from crop to crop, resulting in a lack of universality in related planting and harvesting equipment. The planting and harvesting methods of crops are very different, and the mechanisms of mechanized planting and harvesting are also complicated, constituting an important factor restricting the development of their mechanization. In-depth investigation of the mechanisms of mechanized planting and harvesting of different crops, as well as constantly improving the quality of mechanized planting and harvesting, are some of the challenges of modern agriculture. Precision planting and harvesting agricultural equipment can effectively improve operational quality.

This Special Issue focuses on precision planting and harvesting methods as well as the technologies for agricultural equipment to improve the operational quality and advance the development process of modern agriculture. This issue will fully embrace inter- and trans-disciplinary studies from multiple disciplines (agricultural science, soil science, mechanical engineering, information engineering, mechanics, etc.). It is encouraged to reveal the mechanisms of precision planting and harvesting and the optimization of operational parameters through a combination of theory, experiment, and simulation. In particular, the application of the latest technologies, such as artificial intelligence, is encouraged to help improve the operational quality of precision planting and harvesting using agricultural equipment. Research articles will cover precision planting and harvesting of a variety of different crops. All types of articles, such as original research, opinions, and reviews, are welcome.

To address the issue of reduced yield in the second season caused by damaged stubbles resulting from being compressed during the harvesting process of the first season’s ratoon rice, a device for rectifying the compressed stubbles was designed. Utilizing the DEM-MBD coupling simulation method, a simulation analysis was conducted to determine the range of key parameters and verify the feasibility of the solution. Using rotational speed, forward speed, and stubble entry angle as experimental factors and stubble rectification rate and second-season yield as evaluation metrics, a three-factor, three-level Box–Behnken response surface field trial was conducted. The theoretically optimal working parameter combination was found to be a forward speed of 1.4 m/s, device rotational speed of 75 rpm, and stubble entry angle of 39°. Under these conditions, three parallel experiments were performed, resulting in a rectification rate of 90.35% in the mechanically harvested and compressed area and a second-season yield of 2202.64 ± 35 kg/hm2. The deviation from the numerical simulation results of parameter optimization was less than 5%. These findings suggest that the designed stubble rectification device for ratoon rice can meet the requirements of stubble rectification during the first-season harvest of ratoon rice. Furthermore, it provides valuable insights for reducing harvest losses in the first season and further improving the level of mechanized harvesting for ratoon rice. Full article
