Nutrient growth, apical dominance is controlled, promote the formation of bud, the back branch of 2~3 branches of top layer different directions growth does not stay
Fruit, send out young sprout and stay more.
Further, preferably 3 major branches, are specifically included:3 are selected to be mutually in the branch sprouted below the clip bud
The branch at 110 °~130 ° angles is cut off between major branch at a distance of 35cm~45cm, others as major branch.
Further, the tree crown is excellent cuts, and specifically includes:Cut off sick branch in tree crown, rugosity below 0.5cm and blade it is dilute
Few thin and delicate branch, overlapping branch and dense branches, make in tree crown that sprig is non-cross, non-overlapping copies.
Further, the summer carries out trimming to tree crown and specifically included:Remove useless rudiment, wipe out useless young sprout and
Root sprout tillers, wipe out the branch that can abrade fruit.
A kind of pomegranate pruning method for preventing from day from burning harmful provided by the invention is according to the principle of evacuation layering by pomegranate tree
Be trimmed to 3~4 layers, top layer stays 2~3 branches that different directions grow, and the back branch of top layer branch does not stay fruit typically, and this 2
~3 branches are evened up from horizontal direction, can be formed covering umbrella shape on pomegranate fruitful branch top, be avoided direct sunlight to pomegranate fruit
On, it can obviously reduce the evil of burning day of fruit.
