施設園芸ハウスにおける環境調節方式（第４報）作期別，気象環境および消費エネルギーの実態とトマトの生育，収量との関係

タイトル（英文）

STUDIES ON ENVIRONMENTAL CONTROL SYSTEM IN GREENHOUSE (4) -RELATION BETWEEN THE FACTORS AFFECTING TOMATO PRODUCTIONAND CROPPING PERIOD-

概要 （図表や脚注は「報告書全文」に掲載しております）

施設園芸における生産性の向上，とりわけエネルギーの利用効率の向上が重視されている。環境調節においては，環境に対する作物の生育反応と操作機器の特性の活用が重要と考え，日射量に基づいて温室内温度，炭酸ガス濃度および温度などの環境要素を複合的に調節する方式を開発した。本報告は，新しい調節方式における設定値の実地における検証を目的として，トマトの養液栽培を対象に４つの作期における生育・収量と消費エネルギーとの関係について実験的に明らかにし，作期が異なる場合の設定値策定に関する指針を得た。

概要 （英文）

IN THE RECENT SEVERE ENERGY SITUATION,THE GREENHOUSE AND PLASTIC GREENHOUSE CULTURE NEEDS TO HAVE HIGH EFFICIENCY OF CROP PRODUCTION,ESPECIALLY IMPROVEMENT OF ENERGY UTILIZATION. A MULTI-ELEMENT CONTROL SYSTEM WHICH CONTROLS CLIMATE FACTORS SUCH AS TEMPERATURE,CONCENTRATION OF CARBON DIOXIDE AND HUMIDITY ACCORDING TO THE CHANGING INTENSITY OF THE SOLAR RADIATION,HAS BEEN DEVELOPED TO MEET THE NEED FOR IMPROVED ENERGY USE EFFICIENCY.THE AUTHORS HAVE CONTINUED INVESTIGATION OF THE APPLICABILITY OF THIS SYSTEM WITH CALTIVATION EXPERIMENTSAT THE AKAGI AGRICULTURE EXPERIMENTAL STATION IN GUNMA PREF. IN THIS PAPER,THE RELATIONSHIPS BETWEEN THE TOMATO PRODUCTION,ENVIRONMENTAL CONDITIONS,AND ENERGY CONSUMPTION UNDER SAME SET POINTS DURING FOUR CROPPING PERIODS IS DESCRIBED.THE FIRST CROPPING PERIOD WAS STARTED IN SEPTEMBER 1978 AND CROPPED UNTIL FEBRUARY 1979,THE SECOND WAS FROM NOVEMBER 1978 TO APRIL 1979,THE THIRD WAS FROM DECEMBER 1978 TO MAY 1979 AND THE FOURTH WAS FROM FEBRUARY 1979 TO JUNE 979. FUEL OIL AND ELECTRICITY CONSUMPTION PER UNIT WEIGHT OF TOMATO PRODUCED WERE:1ST CROPPING PERIOD;1.24 1/KG,1.23KWH/KG,2ND CROPPING PERIOD;1.88 1/KG,1.71KWH/KG,3RD CROPPINGPERIOD;1.09 1/KG,0.76KWH/KG,4TH CROPPING PERIOD;0.51 1/KG,0.52KWH/KG.
