The objective of this study was to investigate the actual situation of greenhouse water use and its implications for irrigation planning. To achieve this actual water use in both the greenhouse and the immediate surrounding uplands fields were examined. The micrometeorological conditions and the soil moisture content within and outside the greenhouse were measured, and from the micrometeorological data the estimation of the water requirements of some plants were estimated.The experiments conducted are as follows :1) The micrometeorological conditions within and outside the greenhouse at Soja City area (i.e.Egg Plant), Okayama Prefecture, and Daiei Town area (i.e.water melon), Tottori Prefecture, were measured. Also, the soil moisture content and irrigation amount within the greenhouses was measured.In comparing the results the meteorological measurements, the fact that the temperature was high with solar radiation being low within the greenhouse was confirmed. Using meteorological data … More of the greenhouse the Penman equation was used to estimate evapotranspiration of the egg plant and water melon. The results obtained compared fairly well with evapotranspiration estimated from the water balance of the greenhouse. It was concluded that the Penman equation can be used to estimate water use in a greenhouse with a fair degree of accuracy.2) In this study micrometeorological data was collected at Tohaku town (i.e.lawn field), Tottori Prefecture, and Daiei Town (i.e.Broccoli field). Also, soil moisture content and rainfall amount were measured.3) The actual water use situation in the Tohaku Irrigation Project district (i.e.Tohaku town and Daiei town, Tottori Prefecture) was investigated. This involved a comparison between the hourly discharge from farm ponds in the area and the water use at the farm level. Also, a questionnaire was prepared to investigate water use at the farm level in relation to the kind of crop.The investigations revealed that the peak discharge from the farm ponds was in the morning and evening. This, however, did not interfere with the operation and maintenance of the farm ponds. Also, the amount of discharge from the farm pond fluctuated with rainfall amount in which more water was used during long, clear, dry days. The time, amount, and method of water application also differed with respect to the kind of crop, and with respect to whether crops were grown in greenhouses or in the open field. Less

本研究的目的是调查温室用水的实际情况及其对灌溉规划的影响。为了实现这一目标，我们对温室和周围高地的实际用水情况进行了研究。测量了温室内外的微气象条件和土壤含水量，并根据微气象资料估算了部分植物的需水量。试验内容如下：1)测定了冈山县大豆城地区（即茄子）和鸟取县大成镇地区（即西瓜）温室内外的微气象条件。测定了温室内土壤含水量和灌水量。通过与气象测量结果的比较，证实了温室内温度高、太阳辐射低的事实。利用温室的气象资料，利用Penman方程估算了茄子和西瓜的蒸散量。所得结果与温室水分平衡估算的蒸散量相当吻合。结果表明，Penman方程可以较准确地估算温室的用水量。2)本研究采集了鸟取县东北镇（草坪田）和大荣镇（西兰花田）的微气象资料。测定了土壤含水量和降雨量。3)调查了东北灌溉项目区（即鸟取县东北镇和大成镇）的实际用水情况。这包括对该地区农场池塘每小时的排放量和农场一级的用水量进行比较。此外，还编制了一份调查表，调查农场一级与作物种类有关的用水情况。调查结果显示，养殖场池水排放高峰出现在早晨和傍晚。然而，这并不妨碍农场池塘的操作和维护。此外，农场池塘的排水量随降雨量而波动，在长、晴朗、干燥的日子里使用了更多的水。浇水的时间、数量和方法也因作物种类不同，以及作物是在温室里种植还是在露天种植而不同。少
