Method for afforestation of sands and the like
First Claim
1. A structure used for afforestation of sands and the like, said structure comprising a heat-insulating outer cylindrical body with a prescribed sectional area and length, and a heat-insulating inner cylindrical body with a prescribed sectional area and length, said inner cylindrical body being filled with soil for vegetation containing a water-holding material and being inserted into a hole formed at the center of the outer cylindrical body, wherein the outer cylindrical body is provided with a water container at its lower ends, said water container functioning as a weight and supplying water to the soil upon breakage.

Abstract
A method for afforestation of sands and the like and a structure used for said method. The method and structure permit trees and vegetables to take root and grow easily and certainly in tropical arid land. The method comprises digging the ground to form a vertical hole with a prescribed sectional area and depth, fitting an outer cylindrical body into the hole, filling the outer cylindrical body with soil containing a water-holding material, making a hole with a prescribed sectional area and depth at the center of the soil in the outer cylindrical body, placing in the hole an inner cylindrical body with a prescribed sectional area and length which is filled with soil containing a water-holding material and has a large number of vent holes in its lower section, watering the soil in the outer cylindrical body and the inner cylindrical body so that the water-holding material absorbs sufficient water, sowing a seed or transplanting a nursery tree in the soil in the inner cylindrical body, and growing the plant, with the outer cylindrical body preventing water from escaping from the soil therein, and the soil in the outer cylindrical body isolating the soil in the inner cylindrical body from the ground heat, thereby keeping the soil for vegetation in a wet condition.
