Wine grape production areas exist many questions,such as soil barren,low utilization rate of water,unstable production restricts the development of industry in the eastern foot of Helan Mountain.Through field experiment and laboratory analysis,different irrigation quota,different irrigation gradient were set to study the influence of regulated irrigation on the growth and development of wine grape(‘Cabernet Gemischt'),as well as quality and photosynthesis.The results showed that,the increase of irrigation quota and irrigation frequency could promote plant height,shoots length,deputy shoot number and increase the number of effective utilization of water,watered 10 times,irrigation water with 4 950m~3·hm~(-2) could improve the quality effectively,but watered 20 times,irrigation water with 5 850m~3·hm~(-2) reduced the soluble sugar,total acid,tannins,anthocyanins significantly.Increasing irrigation was helpful for production and single grain weight increased in the growing period of wine grape.Instead,too much water would restrain the growth of the ear.Watered 10 times,irrigation water with 4 950m~3·hm~(-2) was suitable for the region's high quality wine grape cultivation.
