Saplings and pruning methods citrus tree shape should adopt the natural round shape and tower shape, the trunk height of about 30cm, the main branch 3-7, the main branch spacing 10-15cm, the main branch and trunk extension line angle of about 35 -45, leaving the first main branch about 30cm away from the trunk at the main branch, leaving 2-3 deputy main branches for each main branch. For the cultivation of the backbone shoots, three or four classifications are adopted, that is, the main trunk leaves 3-4 main branches, each main branch leaves 3-4 main main branches, and the preserved new shoots, leaving 5-10 in the early exhibition of young leaves. Leaf picking. Generally spring shoots stay 6-8 pieces, summer shoots stay 5-7 pieces, autumn shoots stay 8-10 pieces, and crown top leaves 1-3 more leaves.
The adult tree pruning method for the dense branches according to the "three stays two", "five stays three" methods to stay weak and weak, sparse branches, branches and pests. For the lower shading of the pendent branches or incapacitating pendulous branches from the base of the sparse, for better growth of the pendent branches can be left to retract the horse-bearing branches year by year, so that the branches raise. For branches with internal branches, except for dense branches, branches without branches, and branches and branches with serious diseases and pests, except for those with severe branches and limbs, other shoots should be retained as much as possible. Toadstools that disturb the tree shape should be removed from the base as early as possible. The leggy branches at the canopy gap can be used. When it grows to 25cm, it picks up the heart, promotes its branching, and forms a new branch. If the resulting mother shoots are two or three shoots, cut off the top 1/3-1/2, and the leaves with robust leaves can be cut short.
