The greenhouse culture in Japan has developed for controlling suitable growing conditions in spite of excess rainfall in summer season and too much low temperature in winter season. The greenhouse culture has many advantages. It enable to grow many kind of crops, which are difficult to grow in the open field and it enable to grow high qualified crops which are required by consumers.Water consumption conditions in a greenhouse complicated by the artificial climate and soil moisture control. Micro irrigation system such as drip, mist and micro sprinkler used in greenhouses complicated the evapotranspiration phenomena. To cope with these difficulties, the present study proposes an analytical method for determining water demand. First, radiation balance at the greenhouse wall is discussed, Second, a crop architecture model is proposed to estimate the radiative environment at all growing stages of crop canopy. Third, a water flow model in soil-plant systems which includes three dimensional soil moisture flow and crop transpiration is proposed. These models are applied for controlling irrigation scheduling.

日本的温室栽培是为了控制适宜的生长条件，尽管夏季降雨过多，冬季气温过低。温室栽培有很多优点。它可以种植许多在露地难以生长的作物，并且可以种植消费者需要的高品质作物。由于人工气候和土壤湿度控制，温室内的耗水条件变得复杂。温室中使用的滴灌、雾灌、微喷灌等微灌系统使蒸散现象变得复杂化。为了应对这些困难，本研究提出了一种确定需水量的分析方法。首先，讨论了温室墙的辐射平衡；其次，提出了作物结构模型来估计作物冠层所有生长阶段的辐射环境。第三，提出了土壤-植物系统中的水流模型，其中包括三维土壤水分流和作物蒸腾作用。这些模型用于控制灌溉调度。
