2. Look at the amount of buds: the amount of buds is large, the amount of pruning is large, and the degree is appropriately aggravated. Strictly control the ratio of flower buds to leaf buds at around 1:20; Young trees with few buds leave more flowers; Prune the branches and branch groups without flower buds again and update the bearing branch groups.
3, look at the tree potential: strong trees are lightly cut, straight and strong, and stay aside to promote the formation of flower buds; Re-cutting down weak trees, removing weak branches and renewing weak old branches;
4. Look at the variety: those with strong budding ability and stout branches, such as Red Fuji and Guoguang, should be more sparse and less cut, leaving the middle branches.
