Mineral elements absorption and content of Lactuca sativa under different spectral component conditions were studied by ICP-AES technology. The results showed that: (1) For Lactuca sativa, the average proportion for Ca : Mg : K : Na : P was 5.5 : 2.5 : 2.3 : 1.5 : 1.0, the average proportion for Fe : Mn : Zn : Cu : B was 25.9 : 5.9 : 2.8 : 1.1 : 1.0; (2) The absorptions for K, P, Ca, Mg and B are the largest under the LED treatment R/B = 1 : 2.75, red light from fluorescent lamps and LED can both promote the absorptions of Fe and Cu; (3)The LED treatments exhibiting relatively higher content of mineral elements are R/B = 1 : 2.75 and R/W = 1 : 1 while higher dry matter accumulations are R/B = 1 : 2.75 and B/W = 1 : 1.
采用电感耦合等离子体发射光谱（ICP - AES）技术研究了不同光谱成分条件下生菜矿质元素的吸收及含量。结果表明：（1）生菜中Ca:Mg:K:Na:P的平均比例为5.5:2.5:2.3:1.5:1.0，Fe:Mn:Zn:Cu:B的平均比例为25.9:5.9:2.8:1.1:1.0；（2）在LED处理R/B = 1:2.75条件下，K、P、Ca、Mg和B的吸收量最大，荧光灯的红光和LED的红光均能促进Fe和Cu的吸收；（3）矿质元素含量相对较高的LED处理为R/B = 1:2.75和R/W = 1:1，而干物质积累量较高的处理为R/B = 1:2.75和B/W = 1:1。
