STUDIES ON ENVIRONMENTAL CONTROL SYSTEM IN GREENHOUSE(6) CULTIVATION TRIALS AT SEVERAL SITES AND REFERANCE DATA FORSET POINTS OF CONTROL

概要 （図表や脚注は「報告書全文」に掲載しております）

温室など施設内の環境調節を作物の生理特性にあわせて行う新しい環境調節法（複合環境調節法）のトマトを対象とする栽培連絡試験を気象条件の異なる５場所で実施した。主な結果はつぎの通りである。（１）省エネルギーを目標とする設定値において，単位収量当たりの燃料，電力消費量などの生産原単位を実験的に把握するとともに，普遍的な設定値として利用できることを明らかにした。（２）暖房用燃料，電力消費量を推定するための基礎資料を得ることができた。（３）供試装置の実用化の見通しが３年間にわたる栽培連絡試験により明らかになった。

概要 （英文）

THE PURPOSE OF AUTOMATIC ENVIRONMENTAL CONTROL IN GREENHOUSE ARE TO REDUCE LABOR COSTS,SAVE ENERGY AND IMPROVE YIELDS. A MULTI-ELEMENTS CONTROL SYSTEM WHICH CONTROLS CLIMATE FACTORS SUCHAS TEMPERATURE,CONCENTRATION OF CARBON DIOXIDE AND HUMIDITY ACCORDING TO THE CHANGING INTENSITY OF THE SOLAR REDIATION,HAS BEEN DEVELOPED TO MEET THE NEED FOR IMOPROVED ENERGY USE EFFICIENCY. THE STUDY GROUP OF MULTI-ELEMENTS CONTROL SYSTEM WITH THE CRIEPI HAD CONTINUED INVESTIGATION OF THE APPLICABALITY OF THIS SYSTEM WITH CULTIVATION EXPERIMENTS AT SEVERAL SITES. THE STUDY GROUP CONSISTS OF THE AGRI-ELECTRIFICATION EXPERIMENTAL STATION OF THE KYUSHU ELECTRIC POWER CO.,IN SAGA PREFECTURE,THE YAMAGUCHI COLLEGE OF AGRICULTURE,THE CHUGOKU ELECTRIC POWER CO.,THE KUREHA AGRICULTURE EXPERIMENTAL STATION OF THE HOKURIKU ELECTRIC POWER CO.,IN TOYAMA PRE.,THE BIO-LOGY LABORATORY AND THE AKAGI AGRICULTURE EXPERIMENTAL STATION OF CRIEPI. THE RESULTS ARE SUMMARIZED AS FOLLOWS; (1)THE RELATIONSHIP BETWEEN TOMATO PRODUCTION,ENVIRONMENTAL CONDITIONS,ANDENERGY CONSUMPTION UNDER SET POINTS FOR SAVING ENERGY WAS REVEALED THROUGH THE CULTIVATION EXPERIMENTS. (2)BASIC DATA FOR ESTIMATION OF FUEL OIL OR ELCTRICITY CONSUMTION DURING VARIOUS CROPPING PERIOD WERE OBTAINED. (3)PRACTICAL APPRECIATION OF THIS SYSTEM BECAME CLEAR THOROUGH THE CULTIVATION EXPERIMENTS AT FIVE SITES DURING THE THREE YEARS.
