利用養液薄膜法(NFT)栽培葉菜類

Abstract

傳統上土壤式栽培作物的主要介質，但因其含有各種阻礙作物生長發育的限制因子，而利用養液栽培可突破土壤中肥料因日照及降雨所造成的蒸散及流失，根部因乾濕度變化劇烈，導致水份供應不平衡或氧氣不足，而降低生長速度等缺點。 Due to a lot of limiting factor's for plant growing in soil as medium of the traditional cultivation method, the rate of plant growth and development have much retarded as a result of nutrients, oxygen and water supply inadequated. To improve the production of the leaf-vegetable crop, a Nutrient Film Technique has been introduced in the Highland Experimental Farm National Taiwan University.
