Abstract: The aim was to optimize micro-sprinkling spraying irrigation technique. The effects of different irrigation techniques on the physiology and yield indexes including grape branch number, leaf number and internode length were studied. All of the physiology indexes showed certain regularity of different irrigation techniques. The leaf area index presented a correlation with the branch number, leaf number and leaf area. Among different treatments, WP4 and WP5 had the maximum leaf area index, followed by WP2 and WP3, and the control group had the minimum value. In the aspect of yield, the yield of control group was 29275.5 kg/hm2, which was only higher than that of WP5 (28591.5 kg/hm2). WP3 had the maximum yield value of 38313 kg/hm2, 30.9% higher than that of control group, followed by WP1, WP2 and WP4, which was 33906 kg/hm2, 33361.5 kg/hm2 and 32124 kg/hm2 respectively. The grape had higher yield under the micro- sprinkling spraying irrigation technique with the irrigation quota of 9150 m3/hm2, once per day for 1-2 hours, and the water spray quantity was 105-120 m3/hm2 each time.
