1, transverse branches and long branches are cut off from the base in principle, but when the middle and lower parts of the crown are empty, they can be appropriately cut short as regenerative branches or fill gaps; Dense branches should be trimmed properly, and those that are too long should be trimmed.

2, small citrus reticulata dead branches, branches with serious pests and diseases, should be cut off from the base, so that small citrus reticulata can grow better.

3. The old branches of Little citrus reticulata should be shortened, updated or deleted, and the length of the updated branches depends on the strength and position of the branches.

Extended data:

Pruning requirements in different growth periods:

(1) Full-fruiting period: The height of citrus reticulata is generally controlled below 250cm, the crown is open, the periphery is concave and convex, the branches grow healthily, the thickness of green leaf layer should be above 100cm, and it is ventilated and transparent, resulting in three-dimensional effect. Control the intersection between rows, and the crown coverage rate is 75% ~ 85%. Pruning suitable trees, deleting secrets and keeping sparse, removing the weak and keeping strong; Cut and stay, cut outside and stay inside; Cut down more trees and plant more flowers, and cut down less trees and plant less.

(2) Aging period: pruning small citrus reticulata, renewing or thinning old fruit branches, forcibly sprouting new fruit branches in the inner chamber or lower part, keeping tillers, arranging them in a balanced way, and pruning weak trees moderately.
