无土栽培能防止土壤传染的病害,省水、省肥、高产,并能生产无污染的蔬菜,是农业生产上的一种革命。无土栽培的主要方式有袋培,岩棉培,深水岩棉培,基质水培,NFT,喷雾栽培和水雾培等。其生产成本以袋培最低,在我国应用效果良好,应首先进行推广.基质水培可以在部分经济条件较好的地区应用,NFT 系统初期投资大,用电多,当前在我国不宜大面积推广,但时无土栽培的科学研究应该加强。
Soilless cultivation can prevent soil-borne diseases, save water, save fertilizer, produce high-yield and produce pollution-free vegetables. It is a revolution in agricultural production. The main methods of soilless culture bag culture, rock cotton culture, deep water rock and cotton culture, matrix hydroponics, NFT, spray cultivation and water spray cultivation. Its production cost is the lowest in bag culture, and its application effect is good in our country, it should be popularized at first.Matrix hydroponics can be applied in some areas with better economic conditions, NFT system has large initial investment and electricity consumption, and should not be widely promoted in our country at present However, the scientific research of soilless culture should be strengthened.
