无土栽培通称水培,在我国有悠久的历史,生豆芽、养水仙以及船户携带的“漂浮菜园”都是无土栽培。但这都是原始的。把现代无土栽培用于作物生产的首推美国。加利福尼亚大学的植物生理学教授格里克博士,他于1929年种植西红柿结果西红柿长到7.5米高,结果实14千克。这一成果在社会引起了很大反响。1933年他申请了在水中施肥的专利,1935年在他的指导下进行了大规模的生产试验,最大的面积将近一公顷。同时美国的中西部出现了砂培和砾培技术。并很快传播到欧洲的一些国家以及印度、日本等国。无土栽培长期处于试生产阶段。最先把无土栽培用于生产的是军事部门,二次世界大战期间美国泛美航空公司在太平洋中的荒芜威克岛上种植蔬菜,为过往的乘客和服务人员提供新鲜蔬菜,以后英国农业部
Soilless culture, known as hydroponics, has a long history in our country, raw sprouts, daffodils and “floating garden” carried by the coffers are soilless culture. But this is all original. Use of modern soilless culture for crop production devaluation of the United States. Dr. Grick, a professor of plant physiology at the University of California, California, who planted tomatoes in 1929, grew 7.5 m tall and achieved 14 kg. This result aroused great repercussions in society. In 1933 he applied for a patent for fertilization in water. Under his direction, he conducted a large-scale production test in 1935 with a maximum area of nearly one hectare. At the same time, the sand culture and gravel culture techniques emerged in the central and western United States. And soon spread to some European countries as well as India, Japan and other countries. Soilless culture long-term trial production stage. The first to use soilless culture for the production was the military sector. During World War II, Pan American Airlines planted vegetables on the deserted Wake Island in the Pacific to provide fresh vegetables to past passengers and service workers, unit
