Focusing on the problem of lacking suitable bed former for permanent raised beds (PRB) in one crop a year oasis agricultural region of northwest China, 1QL—70 bed former for PRB was designed, and the parameters of key components were analyzed and confirmed for bed-forming plough, combined forming-pressing device etc. Through adopting cultivated-type plough, the new bed-former could plough and smash the soil effectively. Combining with cylinder roller, the combined forming-pressing device could not only form the bed shape, but also press the beds effectively. Experiment results showed that the bed former was effective in forming and renovating the beds. Bed dimension and surface evenness after forming and renovating could meet the requirements of the agronomy in Hexi Corridor.
