Development of air conditioning system and labor saving technology for efficient hydroponic cultivation

概要 （図表や脚注は「報告書全文」に掲載しております）

中国電力（株）と（財）電力中央研究所は、両者の研究成果をベースにして中国地域に適用できる水耕栽培システムを開発するために、（株）環境リサーチを加えて３者で共同研究を行った。中国電力技術研究センターの中に実験装置を設置し実験を行った。 遮光カーテンと温室屋根の隙間換気および局所冷房方式により、夏期の冷房負荷が大きな中国地方で、夜間電力利用空調の冷房効果を高める工夫をした。 栽培装置上での植物の移動にジャッキとワイヤーを利用し、さらに自動袋詰め機を利用した収穫により、栽培作業を１名で行える見通しを得た。また、ホウレンソウ、サラダナ、チンゲンサイを年間を通じて栽培できた。 さらに、生産対象植物として特殊成分の含有などで高負荷価値が得られるものや挿し木や組織培養などで増殖された緑化用樹木苗などを選んだ。

概要 （英文）

Today, hydroponic technology using air conditioning and artificial lighting has the potential for agricultural-chemical free and high-productivity plant cultivation. Popularization of such technologies will contribute to promotion of regional agriculture and use of night-time electricity. From this viewpoint, Chugoku Electric Power Co., CRIEPI, and Bio-Environment Research Ltd., has planned cooperative research to develop this technology for the Chugoku area, based on previous results. Experimental facilities were constructed at the Technological Research Center of Chugoku Electric Power Co.. Energy-saving technology, labor-saving technology and suitable plants for cultivation were examined using this facility. A heat pump operated by night-time electricity was installed to store hot and cold water for air conditioning. The space between the shading screen and greenhouse roof was ventilated to reduce the air-conditioning energy, requirements. Furthermore, the hydroponic beds were covered with transparent film which was air conditioned inside. The air conditioning efficiency was improved by these methods. A jack and wire system for moving plants on the hydroponic beds and a harvest system with automatic packing equipment were also developed, permitting cultivation by one person. An efficient method for cleaning equipment after harvesting was examined. To test the performance of the system, spinach, butter head lettuce, and Chinese Chingen cabbage were cultivated. The vegetable plant is economical, agricultural-chemical free, and can also be used to cultivate cuttings and for tissue culture for trees.
