近年来无土栽培在国外十分盛行。许多国家已将无土栽培作为一种新的种植方式,在生产上广泛应用。由于其具有清洁卫生,无污染,管理简便等优点,一些城市的居民还纷纷利用楼顶、阳台无土栽培蔬菜和花卉。但目前国内这方面的资料比较少,种植技术鲜为人知。为此,我们特请北京林学院的马太和教授编译了《花卉、蔬菜无土栽培》,其中包括营养液的配制、各种基质的使用,蔬菜、花卉等的种植方法,以及蔬菜工厂的设计等。从这一期起,我们将连载书中主要章节,供无土栽培工作者及业余爱好者学习和参考。 Soilless culture in recent years is very popular in foreign countries.
