Abstract:

V3, a small-fruited processing blueberry variety widely planted in production, was used as the high grafting rootstock, and five annual shoots of Jewel, Emerald, Star, O'neal, and Misty, which were well performed in the current production, were used as the scion, and the method of seppudial grafting or cutting grafting was adopted. The results showed that the basal stem diameter, shoot length, branch number and survival rate of the five cultivars were significantly better than those of the ground planting control. After 3 years of top grafting, the basal stem diameter, branch length, branch number and survival rate of the five varieties were significantly better than those of the other combinations, while the growth potential and survival rate of the O'Neal and V3 combinations were relatively poor. The statistical results of yield and quality after 3 years of grafting showed that the average yield of the five varieties after 3 years of high grafting was more than ground planting control, and the adaptability of each combination was higher than that of the ground planting control, especially the yield of Jewel and V3 combination was 2.78 times of Jewel single planting.
