Blueberry grafting propagation method

Abstract

The invention relates to a blueberry grafting propagation method, which comprises the following steps: 1) stock selection and treatment: selecting annual vaccinium bracteatum twigs with the diameter of 2-5 mm from a vaccinium bracteatum stock plant which is 3-5 years old, robust and disease-free, pruning the upper parts of the vaccinium bracteatum twigs into flat openings, and pruning the lower parts of the vaccinium bracteatum twigs into horseshoe-shaped oblique cuts; carrying out cuttage on the pruned vaccinium bracteatum twigs in early February and middle February, and using the vaccinium bracteatum twigs as stocks after the vaccinium bracteatum twigs survive after cuttage and grow to March to April of the next year for later use; 2) scion selection and treatment: collecting half-age to one-age base growing branches as blueberry scions with full and active but not completely lignified spores, cutting off the blueberry scions before the spore germination in winter, storing the blueberry scions in wet sand at 1-4 DEG C, and preventing the spore germination in the storage process for later use; 3) grafting treatment: adopting a plate budding method; and 4) management after grafting. The blueberry grafting propagation method is high in grafting survival rate, strong in nursery stock, capable of meeting different soil planting requirements and good in application and popularization value.
