<P>PROBLEM TO BE SOLVED: To provide a method for effectively reducing bacteria and nematodes proliferating in cultivated soil in a cultivation bed and further reducing growth-inhibiting components such as excessive fertilizers and salt, and to provide a cultivation bed for use in the method, and a method for cultivating field crops and paddy crops using the cultivation bed. <P>SOLUTION: The cultivation bed is structured to store cultivated soil in a tank including a water-impermeable bottom part and a water-impermeable frame body and to allow filling of water on the cultivated soil and drainage of water from the cultivated soil. In the cultivation bed, water is filled for a predetermined period, and then water is drained from the cultivated soil to dry the cultivation bed. In a preferable cultivation bed, a bottom part is inclined to improve drainage of water from the cultivated soil, and a corner part of the frame body or a part of the frame body on the bottom side can be opened. <P>COPYRIGHT: (C)2013,JPO&INPIT |
