The nutrients and water supply control for quality control is important in the cultivation of the gardening crops. In an existing cultivation device, The nutrients and water supplycan be controlled extremely or not at all. It is sure to be able to keep theoretically accurate with membrane culture which Reverse osmosis(R.O.)membrane is a semipermeable membrane which allows water to pass freely and ionic compounds slowly except large molecules. By using this membrane, we developed cultivation system. This system is constructed of a solution and vessel which floats on a solution. The vessel is about 2cm in height and the bottom is sealed with the R.O.membrane. Plant is placed directly on the R.O.membrane in this vessel. Water and nutrients are supplied to the plant from the solution through the R.O.membrane. Water and nutrient supply is controlled by the water potential and nutrient concentration in the solution. It is possible to maintain a water deficit in the root zone by using a high osmotic pressure solution. In an experiment, with a high osmotic pressure solution, spindly growth in an indoor environment was completely prevented in coleus(Coleus blumei Benth.). Using this system, coleus plants were maintained without spindly growth for 6 months indoors, using only deionized water. There is a possibility that by using this system, plants that are not normally used as indoor plants due to spindly growth. Additionally, weight and size of the planting pot can be reduced since no culture medium is required.Through the membrane fitted to the culture vessel, microbestatics(mainly composed aluminum)and microbes on the outside are removed and fresh nutrients and water can be supplied into culture vessels. We supplied the fresh culture medium containing sucrose by this method and grew healthy plants in the sterilized culture vessel, under unsterilized conditions. By using this culturing system the medium(contained Phyto-hormones)can be refreshed without replanting.

在园艺作物的栽培中，用于质量控制的养分和供水控制非常重要。在现有的栽培装置中，养分和水分的供应可以被极其控制或完全不控制。膜培养肯定能够保持理论上的准确性，反渗透（R.O.）膜是一种半透膜，它允许水自由通过，离子化合物缓慢通过（除了大分子）。通过使用这种膜，我们开发了培养系统。该系统由溶液和漂浮在溶液上的容器构成。容器高约2cm，底部用R.O.膜密封。植物直接放置在该容器中的 R.O. 膜上。水和养分通过 R.O. 膜从溶液供给植物。水和养分的供应由溶液中的水势和养分浓度控制。通过使用高渗透压溶液可以维持根区的水分不足。在一项实验中，使用高渗透压溶液，完全阻止了锦紫苏（Coleus blumei Benth.）在室内环境中的细长生长。使用该系统，仅使用去离子水，锦紫苏植物在室内可维持 6 个月而不会出现细长生长。通过使用该系统，可能会导致通常不用作室内植物的植物因生长细长而出现问题。此外，由于不需要培养基，因此可以减轻种植盆的重量和尺寸。通过安装在培养容器上的膜，可以去除外部的微生物（主要成分是铝）和微生物，并可以将新鲜的营养物质和水供应到培养容器中。培养容器。我们通过这种方法提供含有蔗糖的新鲜培养基，并在未灭菌的条件下在灭菌的培养容器中生长健康的植物。通过使用该培养系统，可以更新培养基（含有植物激素）而无需重新种植。
