Analysis of the Mineral Elements of Lactuca Sativa under the Condition of Different Spectral Components
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.
