溶液培养植物的研究已有上百年的历史,它对证明无机营养元素的必需性起了决定的作用,并为化学肥料的生产和应用作出了不可磨灭的贡献。但传统的水培技术在大面积生产上使用却一直存在困难。多年来是采用营养液流动,人工通气或加固体填充物来解决水和空气间的矛盾。这些措施设备复杂,管理较困难,经济效益又很低,因此限制了水培在生产上的发展。七十年代末Cooper试验成功一种新 Studies of solution-grown plants have been around for centuries and have played a decisive role in demonstrating the necessity of inorganic nutrients and have made an indelible contribution to the production and use of chemical fertilizers. However, the traditional hydroponics technology has been used in large-scale production has been difficult. Over the years is the use of nutrient fluid flow, artificial ventilation or solid filler to solve the contradiction between water and air. These measures are complex equipment, management is more difficult, low economic efficiency, thus limiting the hydroponic in the development of production. The Cooper test was a new success in the late 1970s
