[Abstract]
This article reviewed the affection of the technology of ridge tillage with ditch irrigation on soil and crop and the water-saving benefits in the oasis irrigation area of Hexi Corridor. It was pointed out that the key technical parameters of ridge tillage with ditch irrigation techniques, the physiological responses of crops and the coupling model of water and fertilizer under ridge tillage with ditch irrigation conditions, and the effects of ridge tillage with ditch irrigation on soil nutrient losses, were the fields necessarily to be studied further.
