前言所谓气培法,是把作物悬置起来,使根部暴露在空气中,定时供给作物营养液,满足作物在生长发育过程中对营养的需要。气培法能充分利用空间,实现立体栽培,更好的提高光、热、水、肥的利用率。气培法与水培法根本不同点是,水培法,将其作物的根固定在装有基质的栽培槽里;而气培法,将其作物的根暴露在空气中悬置起来。同时,水培法和有土栽培一样,只能一层栽植;而气培法,可多层栽植。有的人,把气培法称 Preface The so-called gas culture method is to suspend the crop so that the roots exposed to the air, regular supply of crop nutrients to meet the crop growth and development in the process of nutrition needs. Gas culture can take full advantage of space, to achieve three-dimensional cultivation, better to improve the light, heat, water and fertilizer utilization. The fundamental difference between gas culture and hydroponics is that hydroponics is used to fix the root of a crop in a planting tank equipped with a substrate. In the gas culture method, the roots of the crop are exposed to the air and suspended. At the same time, hydroponics and soil culture, as only one layer of planting; and gas culture method, can be multi-layer planting. Some people, the gas culture law said
