蔬菜无土栽培早在十八世纪初,法国人索尔秀和布森高就已获得成功。到十九世纪三十年代美国人格里克教授,在水培里种植西红柿,有一株高达七米以上,收获14公斤,这一成就,美国人当时称为本世纪美国最伟大的发现。现在世界上研究无土栽培的有四十多个国家。一九五五年成立了国际无土栽培工作组,进行科学讨论和经验交流。我国近几年无土栽培发展也很快,一九五九年全国成立无土栽培育苗攻关小协作组,有近一百多个单位参加,并取得了很大的进展。例如:北京玉渊潭公社已全部使用无土育苗种植蔬莱。我区无土栽培也有较大的发展,主要是应用在育苗技术上。 我所于一九七九年开始进行蔬菜无土育苗试验,在茄果类,黄瓜、芹菜、芫荽等蔬菜上,用我所自拟的五种混合基质和三种用化肥配成的营养液,和国外的二种基质、三种营养
Soilless cultivation of vegetables As early as the early eighteenth century, the French Sol show and Boussougou have been successful. By the 1930s Professor Gerik, an American who planted tomatoes in hydroponics, had a success rate of more than seven meters and a harvest of 14 kilograms, the American was then called the greatest American discovery of this century. Nowadays there are more than forty countries studying soilless culture in the world. In 1955, the International Soilless Culture Working Group was established to conduct scientific discussions and exchange of experiences. In recent years, the development of soilless culture in China has also been very rapid. In 1959, a small collaborative group of soilless cultivation and seedling research was set up in the country, with nearly 100 units participating and great progress made. For example: Beijing Yuyuantan commune has all used soilless nursery plant vegetables Lai. Soilless culture in our area also have greater development, mainly used in seedling technology. In 1979, I started the vegetable soilless seedling experiment. I used the five kinds of mixed matrices and three kinds of nutrient solutions formulated with fertilizers on solanaceous vegetables, cucumber, celery and coriander. , And two kinds of foreign matrix, three kinds of nutrition
