Cultivation of hazel tree with the crown having the form of a vertical spindle on a support represents a new way of planting and cultivation of hazel trees. FIG. 3 shows cultivation of hazel tree in double rows, which have crowns in the form of a vertical cylinder shown in FIG. 1. A skeleton of the basic tree consists of a central line without trunk, having on it radially arranged primary and yielding branches. During the life of a basic tree branches are cut forming the crown on the line that may grow up to 3 or 5 meters and the external diameter of the spindle of the crown may be from 0.5 up to 1 meter. The skeleton is weak and the basic trees are leant against supports. |
