"Four Measures" for Cherry Tree Autumn Shears

A few days ago, the author stated that from August to October, the big cherry tree was in the late stage of flower bud morphological differentiation. At this time, pruning can improve the tree structure and lighting conditions, promote nutrient accumulation, enrich the shoots and revitalize the inner chamber.

Thinning and thinning are mainly to remove buds, dry branches, long branches, competitive branches, diseased and diseased branches, thin branches, drooping branches, overdense branches, overlapping branches and vernal branches in the crown, as well as the apex of branches and branch groups. The strong strips that are drawn to open the canopy light path, improve the light in the inner chamber, and enrich the flower buds. In a year, a tree can be sparse up to 2 large branches, but don't form opposite injuries.

Branching Practice has proved that the branch opening angle of big cherry in autumn is better than that in spring. The best time to pull branches in autumn is from August to September. During this period, the opening angle of the branches can make all buds develop evenly, and there are fewer upright branches on the back, which has a better effect. The base angle of the main branch of the first layer of big cherry is about 80 degrees, the tip angle is 65 to 70 degrees, and the auxiliary branch opening angle is 80 to 90 degrees. When pulling the branch opening angle, pay attention to move the drawstring or falling object in time to prevent the tip angle. Heart grows.

When cutting branches, the temporary branches that are more than 2 years old are slowly released when pruning in spring and summer. The long branches and large leaf bud branches that were withdrawn in the summer "topping", as well as perennial large and medium branch groups and auxiliary cultivation branches. The space needs to be retracted and trimmed to suppress the front and back, concentrate nutrition, and promote flower bud formation. In addition, for weakly growing branch groups, 2 to 3 branches are left to retract and grow stronger.

Topping To make the last topping in late September, to enrich the shoots, enhance cold resistance, and help to survive the winter safely.
