Abstract: Water utilization efficiency, water saving and yield increasing effect, input and output of different mulching cultivation modules of winter wheat were analyzed systematically through field experiment in Weibei Highland, Shaanxi Province. And the mechanism of the yield increasing and the water saving of different mulching cultivation modules also was studied. The result shows that different mulching cultivation modules are better than convention cultivation modules for winter wheat in Weibei Highland, and the ridge mulched plastic film and furrow mulched straw cultivation module is best. The ridge mulched plastic film and furrow mulched straw cultivation module can increase water utilhzation efficiency to 11.59 kg·mm^-1·hm^-2, and water saving of unit grain produce is 37.21%～39.85%, yield increasing of unit water consumption reaches 58.68%～66.25%, output and input proportion is 1.34∶1, which are higher than those of other mulching cultivation modules. Ridge mulched plastic film and furrow mulched straw cultivation modules is one of the efficient methods to improve winter wheat yield of highland and economic benefits.
