Abstract: In order to explore the technology and the corresponding effects of wheat water-saving cultivation, the impacts of irrigation method and film-mulching combination on yield and components, green area of stem, leaf, and spike were studied. The results indicated that both infiltration irrigation and film-mulching could raise yields, although their combination has more remarkable effect. Under controlling 459mm total water consumption condition, the 20cm and 40cm on infiltration irrigation and film-mulching increase the production by 20.34% and 20.16% than CK, and increase by11.11% and 13.67% with open-air and recharging deep water. Different treatments have remarkable effect on green area of stem, leaf and spike and their proportion. With different cultivation, non-leaf photosynthetic organs occupy proportion of total green area between 61.33%~62.69% in the flowering stage.
