Abstract:: Taking 3yearold ‘Muscat Hamburg’ grape as materials,4 pruning interval treatments of 10 d,15 d,20 d and 30 d were set for the test.Shoot increment,chlorophyll,dry matter,nutrient and fruit quality of ‘Muscat Hamburg’ grape were determined,in order to investigate the pattern pruning effect on growth and fruit quality.The results showed that pattern pruning had significant effect on the growth of shoots.Chlorophyll content of 20 d pruning treatment had maintained a high level,and chlorophyll content of 60 d after the treatment was 1.53 mg/g.Dry matter content of pruning after 10 d was the highest,it was 55.69%.The effect of pruning on nitrogen and protein in shoot was not significant,but potassium content was significantly higher than that of the control.The effect of pattern pruning on grape’s size and color was not significantly,and total sugar content increased significantly.Comprehensive evaluation of all aspects,the treatment of 20 d was the most suitable for Y type rack.
