摘要： Irrigation measures control the grape fruit growth under delayed cultivation facility, finding the suitable range of water regulation to provide theoretical basis for high quality and high yields of the grape. This paper discusses regulated deficit irrigation effects on the facility grape particle size, nitrogen and chlorophyll content in leaves. The experiments showed that there were two distinct high, low peak growth period of grape fruit enlargement. In the early fruit enlargement stage, VS, FS treatment' fruit enlargement rate showed evident re-watering compensation effects, which experienced severe water stress in vining and fruit enlargement stage, later the rate was slow again. Nitrogen and chlorophyll content in grape leaves showed "from high to low, higher again, and reduce" regular pattern in grape growth period. Nitrogen content in leaves of severe water stress (VS, FS, ES, CS) were higher than mild stress treatments(VM, FM, EM, CM) in the stress period, nitrogen content in leaves of high moisture gradient treatment (ES) was significantly higher than the mild water stress EM in initial grape expand period.
