Abstract: [Objectives] To study the effect of mechanical harvesting of main crop on soil rolling and yield of ratooned rice. [Methods] In this study, the harvesting method was optimized and improved through field research and theoretical research. [Results] Compared with farmers' habits, the mechanical harvesting method could significantly increase the working area per unit time and reduce the rolling area in the field, but it would increase the rolling rate of the land or transfer area. At the same time, the optimization method could reduce the soil bulk density in the primary rolling area, but it had no significant impact on soil compactness. [Conclusions] Compared with the farmer's customary method, the optimization method could reduce the crushing and damage of rice piles in the field, increase the seedling rate and panicle extraction rate, thus increasing the yield of rice in the ratooning season.
