Abstract:: Main cultivar of wine grape ‘Cabernet Sauvignon’ were taken as experimental materials at the eastern foot of Helan Mountain，the effect of irrigation cycle on the growth，development，yield and quality of wine grape under drip irrigation were studied，as well as the dynamic changes of soil moisture under different irrigation cycle.The results showed that，irrigation cycle with 8 days increased shoot length and SPAD value significantly，irrigation cycle with 6 days increased nutrient accumulation and yield increased by 29.65% compared with the irrigation cycle of 4 days，at the same time，the contents of total acid and tannin decreased，and the content of total phenols was higher.The law of soil water 〖JP4〗movement was obvious under different irrigation cycle，the lateral infiltration area was mainly concentrated in the 20-50 cm 〖JP3〗of activity range by root zone.
