Surveillance study of the support method to the plant factory by electric power industry. Development trend of plant factory technology in Japan.

概要 （図表や脚注は「報告書全文」に掲載しております）

本研究では、植物工場の国内技術動向を整理するとともに、電気利用機器に関する実用事例のカタログ化と活用推進を図るための技術課題を抽出した。太陽光型植物工場の施設面積別割合は10000～49999㎡の43%が最大であった。生産作物はトマトが最も多く、栽培方式別割合はロックウール水耕の35%が最大であった。人工光型植物工場の設置箇所を電力会社の管内別に整理した。栽培面積別割合は300～999㎡の30%が最大であった。生産作物はレタスが最も多く、栽培方式別割合はDFT・NFTの72%が最大であった。光源別割合は蛍光灯の54%が最大であり、次いでLEDが27%であった。また、川内高原農産物栽培工場など合計4箇所を事例分析した結果、最新の植物工場に導入されている空調や光源などの電気利用機器の導入状況が明らかになると共に、農業の6次産業化には顧客管理システムの導入が重要であることが示された。さらに、人工光型植物工場の本格普及に必要とされる技術課題の抽出を行った。その結果、ソフトウェア技術課題として、植物工場専用品種の開発、栽培可能品目の拡大、栽培植物ごとの最適光波長制御技術および省エネ照明技術が、ハードウェア技術課題として直流電源の効率改善、照明器具の排熱冷却方式の最適化などが抽出された。

概要 （英文）

The technology trends of the plant factory were surveyed. In the sunlight type plant factory, the case where facilities area measures 10000-49999 m2 is the most numerous, and it occupied 43% of the whole. Products were tomatoes and the rock wool hydroponics of the cultivation system was a large number in the sunlight type plant factory. As a result of arranging the location of a plant factory with artificial light according to service area of each electric power company, there were most Tokyo and, subsequently they were Hokuriku. As for the rate of the cultivation area of the plant factory with artificial light, 300-999 m2 was as the highest as 30%, and 1000 m2 or less occupied 85%. The main products are lettuce and, as for the cultivation system, DFT and/or NFT occupied 72% in the plant factory with artificial light. As for the light source of the plant factory with artificial light, a fluorescence lamp and LED were used 27% with 54%, respectively. Next, the field survey was performed for two plant factory with artificial lights, one sunlight type plant factory, and the farmhouse that performs agricultural-products processing and direct sales, and the feature was adjusted in leaflet form. Furthermore, the technical issue needed for the formal spread of plant factory with artificial lights was extracted. Development of the variety only for the plant factory, expansion of the items which can be grown, the optimal light wavelength control technology for every cultivated plants, and energy-saving lighting technology were extracted as software subjects, and optimization of improvement in efficiency of a direct-current power supply and the cooling system of a light, etc. were extracted as hardware subjects.
