1, prune in summer, bud and remove tendrils, erase too many useless twigs at the early stage of growth, tie the new branches with iron wire when they grow to about 3cm to avoid being blown off by the wind, and remove tendrils at the same time.

2. Remove the core and secondary branches, and remove the core about 5 days before flowering to improve the fruit setting rate. Generally, leave more than 5 leaves on the ear and pick the tender tips at the top.

3. After coring, the secondary branches began to sprout, all the secondary branches of the ear were removed, and two leaves were left on the ear before coring. After coring, if there is a secondary secondary tip, the secondary secondary tip or the tertiary secondary tip coming out later, continue to core in the same way.
