Detailed Explanation of Key Techniques for Large-Branch Cutting Propagation of Cherry Blossoms
Cherry blossom propagation previously generally used cherry as rootstock in spring for branch grafting. This method is relatively labor- and material-intensive and is not suitable for the large demand for seedlings in rapidly developing landscaping. In recent years, we have carried out large-branch cutting propagation for seedling cultivation and achieved good results. 1. Selection of cuttings: Select young and robust mother trees, cut annual thick branches from the middle-upper outer part of the canopy, retain the top shoot, cut into 30-40 cm long cuttings, and cut the lower end into a slanted opening. Cuttings cut on the same day must be inserted on the same day, so as
