[0002] Ridging refers to the process of forming a high ridge structure by piling up soil in the farmland. This practice has many benefits and applicable conditions in agricultural planting, especially in the field of flue-cured tobacco. Ridging of flue-cured tobacco fields can prevent waterlogging and drought, reduce diseases, increase ground temperature, facilitate mulch film covering, and help control density. Ridging machines are generally used for large-scale flue-cured tobacco field preparation and ridge making.
