PROBLEM TO BE SOLVED: To utilize a hollow carbonized material stake as a means for helping the relatively stabilized growth/promotion of fruit trees or other plants in drought or on a soil of a quality having weak water retention. SOLUTION: By thrusting or burying the hollow carbonized material stake prepared by carbonization, etc., into the root bed soil part of the plants such as the fruit trees, etc., water from rain or watering is kept as a pool for aiming at the maintenance of water content against natural drought or the soil having weak water retention. At the same time, the occlusion of ventilation of air or carbon dioxide in the soil is prevented by its hollow part. COPYRIGHT: (C)2005,JPO&NCIPI
