所谓无土栽培,是指不用天然土壤,而用配制好的营养液来种植作物的技术,它是人类在农业生产上的一项重大革新。这项技术的奠基人是上一世纪德国科学家沙奇斯和诺普。 1929年,美国加利福尼亚大学教授格利克用营养液种出了1株7.5m高的番茄。他架着梯子摘下14kg果实。从那以后60年来,全世界已有120多个国家可以生产无土栽培的 The so-called soilless cultivation refers to the technology of growing crops with the prepared nutrient solution without using natural soil. It is a major innovation of human beings in agricultural production. The founder of this technology is the last century German scientists Shakis and Knop. In 1929, Professor Glick, a professor at the University of California, produced a 7.5-meter-tall tomato with nutrient solution. He took the ladder off 14kg of fruit. Over the 60 years since then, soilless culture has been produced in more than 120 countries around the world
