This research project was carried out from 1998 to 2000 for the purpose of developing simplified soilless culture systems and growing softwares adapted to a wide range of clim atic and geographical conditions, and sustainable agriculture such as saving fertilizer and water. At that time, full open-roof greenhouses (Cabrio type) were built for controlling several environmental conditions with micro-computers. At first, we investigated the distribution of temperature and solar radiation, and effect of a shade-curtain on high temperature control in these greenhouses. As a result, temperature was almost uniform, but solar radiation varied widely inside the greenhouse, and the shade-curtain enhanced temperature build-up. Also we investigated the physico-chemical properties of several substrates. Results indicated that these organic substrates could replace rockwool. As a preliminary examination, we investigated the effect of substrate volume, and composition on the growth and yield of tomato grown in the open field. Tomato and lettuce were grown on simylated tropical conditions, and established a growing systems using indigenous substrates. From these results, we experimated the nutrients control system based on integrated solar radiation, and recognized that the system is environment-friendly.Through these researches, it is necesary to make further investigation on the absorption of water and fertilizer with respect to plant's growth stage and environmental conditions.

该研究项目于1998年至2000年进行，旨在开发适用于各种气候和地理条件的简化无土栽培系统和生长软件，以及可持续农业，如节省肥料和水。当时，全开放式屋顶温室（Cabrio型）被建造用于用微型计算机控制多种环境条件。首先，我们研究了这些温室内的温度和太阳辐射的分布，以及遮阳帘对高温控制的影响。结果，温度几乎是均匀的，但太阳辐射在温室内变化很大，遮阳帘增强了温度的积累。此外，我们还研究了几种底物的理化性质。结果表明，这些有机基质可以替代岩棉。作为初步试验，我们研究了基质体积和成分对露地番茄生长和产量的影响。番茄和莴苣生长在Simylated热带条件下，并建立了一个使用本地基质的生长系统。通过这些研究，我们对基于太阳辐射的养分调控系统进行了试验，并认为该系统是环境友好的，通过这些研究，有必要进一步研究植物生长阶段和环境条件对水分和肥料吸收的影响。
