Impact of Tillage and Straw Management on Soil Properties and Rice Yield in a Rice-Ratoon Rice System

The rice-ratoon system has long been considered an important economic, time-saving, and labor-saving planting method. Optimal tillage straw management are beneficial to increasing the growth yield of recycled rice. However, there is little research on physical chemical properties soil under management, its effects fertilizer utilization A field experiment was conducted study four types rice in central China during 2020–2021. were no-till with residues retained (NT+S); plow residue retention (PT+S); removed (NT-S); (PT-S). Compared PT, decreased by 38.8% NT, while returning effectively increased regenerated NT+S main season 37.0% ratoon 45.3%. non-returning straw, total porosity, organic carbon, activity β-glucosidase urease, among which TP SOC 8.8% 27.8%, respectively. results showed that could significantly reduce loss caused no-tillage improve structure. No-tillage combined regenerative a green, light, simplified cultivation mode worthy further exploration.
