PREPERATION METHOD OF TREE PLANTING HOLE FOR PREVENTING DESERTIFICATION

摘要

PURPOSE: A tree planting hole producing method is provided to minimize the loss amount of water supplied to trees, and to maximally collect rain water to supply to the trees. CONSTITUTION: The surface of a wild land in which the desertification is proceeded is excavated into a puddle form, and the upper side of the cross section of the obtained puddle is longer than the lower side of the cross section to make a trapezoid shape. A hole (10) for planting a tree is excavated on the center of the lower side of the puddle. Topsoil (20) on the surface of the ground is excavated and collected on one side, and a calcareous layer (30) underneath the surface of the ground is excavated to be loaded on one side of the trapezoid shape toward the outside direction. The topsoil fills the generated furrow and evened before making the hole for planting the tree on the center of the topsoil. The soil generaged from the excavating process forms ridges.
