In this paper, the possibility of using Penman Monteith formula to calculate crop transpiration under plastic film mulching and various effects of plastic mulching are studied. By using the data of winter wheat mulching test in Xinmaqiao Agricultural Irrigation Experimental Station of Anhui Province ASTRI, The calculation formula of the transpiration amount of winter wheat under the condition of plastic film mulching, and analyzed the reason of the change of winter wheat water consumption under mulching.
