摘要： The photosynthetic characteristics and water use of WL323MF at 3 irrigation treatments (60mm, 40mm and 20mm water were applied at the regeneration period and after mowing, respectively) were studied in Beijing's farmland. The results showed that there are the diurnal change with "M" shape in the Pn, Tr and Gs of WL323MF and there are the positive corresponding relationship between the hay yield and the water consumption, the WUE. About 60mm of irrigation could get about 532.74mm of the water consumption and 17925.28kg/ha of alfalfa hay, about 20mm only could get about 389.60mm of the water consumption and 10450.75kg/ha of alfalfa hay.
