PROBLEM TO BE SOLVED: To solve problems of a conventional cultivated field and a greenhouse cultivation means for planting seeds or planting seedlings in a cultivation area and growing the plans till harvesting, wherein the frequency of use of the cultivation area is limited, wherein there is wastefulness of sprinkled water and fertilizers in the cultivation and growing, and wherein heavy expenses are required for measures against pests and continuous cropping and for adjusting the concentration of fertilizers in the cultivation area.SOLUTION: A culture medium in which chaff, smoked chaff charcoal, a modifier, artificial zeolite, shell fossils and quartz are blended is used and the use of soil is reduced for cultivation, so that the cultivated plants are hardly damaged by pests. An aqueous solution containing a fertilizer component is stored under the culture medium for cultivation, and the excess solution is stored in a water storage groove to be circulated so that an irrigation means can be made. A cultivation unit of the cultivation apparatus is made and seedlings are planted and cultivated in the cultivation unit. By changing the cultivation unit for each harvesting, the frequency of use of the cultivation area can be increased, and the harvest will be significantly increased.【課題】 従来の耕作地や温室栽培手段は、栽培地に種を蒔くか苗を植えて収穫するまで栽培する手段である。この栽培手段では、栽培地の利用回数が限られる。栽培育成でも散水や肥料の無駄がある。栽培地は、病害虫、連作障害や肥料濃度の調整に多くの費用を必要とする。【解決手段】もみ殻ともみ殻くん炭と改質材、人工ゼオライト、貝化石、石英斑岩を混入した培地を使用し、土壌の使用を低減して栽培できることで、病害虫に侵されにくくなる。培地の下方に肥料成分を含む水溶液を貯水して栽培をし、余剰の水溶液は、貯水溝に溜めて循環、灌水手段が可能となる。上記栽培装置の栽培ユニットを作り、栽培ユニットに苗を植え込んで栽培し、収穫ごとに栽培ユニットを替えことで、栽培地の利用回数が増え収穫も格段に増大する。【選択図】図３
