Effect of Mechanized Ridge Tillage with Rice-Rape Rotation on Paddy Soil Structure

Ridge tillage is one of the essential methods in China. It affects soil structure by altering soil-water environment. With rapid development agricultural mechanization, mechanized ridge technology that combines modern agriculture with conservation has become a pertinent production hilly regions. However, to date, effects on have garnered little attention. In this study, field plot experiment involving following four treatments: conventional rice and winter fallow (CK1), rice-rape rotation (CK2), wide (BT), narrow (RT) was conducted study aggregate stability porosity. The results indicated could reduce porosity pores > 30 μm diameter increase < 0.5 μm. Furthermore, stability; order average mass geometric RT BT CK2 CK1. treatments agglomeration degree particles, which followed Therefore, effective enhancing structure.
