19世纪,无土栽培曾被认为是梦想。1929年,美国教授格里克在室外用养分水溶液种出一株7米半高的西红柿,收果实14公斤。从此,无土栽培在世界许多国家得到了很大发展,成为竞相研究的新兴农业学科。无土栽培的方法目前,世界上出现了几十种方法,归纳起来主要有五种:水溶液培养法,沙培养法,培养基培养法,混合培养基培养法和营养膜培养法。营养液主要根据植物对养分的需要配制。 In the 19th century, soilless culture was once considered a dream. In 1929, American professor Gerrick planted a 7-meter-and-a-half-height tomato with a nutrient solution of 14 kg outdoors. Since then, soilless cultivation has greatly developed in many countries in the world and has become a new agricultural discipline competing for research. Soilless cultivation methods At present, there are dozens of methods in the world, and there are mainly five kinds of methods: aqueous culture method, sand culture method, culture medium method, mixed culture medium method and nutrition membrane culture method. Nutrient solution is mainly based on the needs of plant nutrients.
