在全密闭植物工厂中水培种植中药蒲公英，以发射不同波段光谱的荧光灯及LED灯作为药材生长光源，并结合ICP–AES技术分析了不同光谱条件对蒲公英无机元素吸收和积累的影响。结果表明：（1）相近的光合有效辐射（PAR）条件下，单一红光R及混合光FLRB有利于水培蒲公英可食生物量的积累，单一蓝光B处理下可食生物量最低；（2）荧光灯 FL 条件下蒲公英地上部分常量无机元素含量比值为 K∶Ca∶P∶Mg∶Na＝79．74∶32．39∶24．32∶10．55∶1．00，微量无机元素含量比值为 Fe∶Mn∶B∶Zn∶Cu＝9．28∶9．71∶3．82∶2．08∶1．00；（3）峰值为660 nm的红光有利于蒲公英对Ca，Fe，Mn，Zn元素的吸收， Cu元素含量受光谱条件的影响不明显；（4）蒲公英地上部分对Ca，Na，Mn，Zn四种元素的积累量均在纯红光R下最高，而对其余六种元素的积累量以混合光FLRB条件下最高。

Dandelion (Taraxacummongolicum)was hydroponically cultured in a completely enclosed plant factory,in which flu-orescence and LED emitting spectra of different bands were used as the sole light source for plant growth.Effects of spectral component on the growth of dandelion were studied and the contents of ten inorganic elements such as K,P,Ca,Mg,Na,Fe, Mn,Zn,Cu and B in dandelion were analyzed by ICP-AES technology.The results showed that:(1 )Under the condition of similar photosynthetic active radiation (PAR),single R or combined spectrums of FLRB were beneficial for biomass accumula-tion,while single B was the contrary;(2 )Macroelements content ratio in Taraxacummongolicum grown under FL was K∶Ca∶P∶Mg∶Na= 79. 74∶32. 39∶24. 32∶10. 55∶1. 00,microelements content ratio was Fe∶Mn∶B∶Zn∶Cu= 9. 28∶9. 71∶3. 82∶2. 08∶1. 00;(3)Red light (peak at 660 nm)could promote the absorptions of Ca,Fe,Mn,Zn,while absorption of Cu was not closely related to spectral conditions;(4)The highest accumulation of Ca,Na,Mn and Zn were obtained in aerial parts of Taraxacummongolicum plants grown under pure red spectrum R,while the accumulation of the rest six elements reached the highest level under the mixed spectrum FLRB.
