The invention discloses a
pruning method for blueberries. The method involves the
pruning time and principle,
pruning of saplings, pruning of mature trees, regeneration and invigoration, pruning in autumn and winter,
bud removing and pruning in summer. The pruning method for the blueberries is characterized by comprising the following pruning step that the pruning time and principle are set, wherein the idea tree form to the blueberries should achieve the purposes that tree bodies are straight, and the tops of the tree bodies are opened; during pruning, firstly, branches with freeze injuries,mechanical injuries or diseases and
insect pests are pruned; secondly, intertwined branches are pruned to avoid infection of the
canker due to mutual friction; thirdly, branches hindering row operation are pruned, and fourthly, short overgrowing branches which are under crown closure are pruned. The method is implemented in the
dormancy period of the branches, pruning should be selected at the early spring in cold northern regions, and at this moment, the branches suffering from freeze injuries can be identified and removed; for warm southern regions, pruning can be conducted after harvestingin summer and the
dormancy period in winter. By effectively pruning plants, larger yield can be achieved, the number of base growing branches can be reduced, and the size of the tree bodies can also be reduced.
