摘要
以罗马生菜为试材,在育苗期、生长前期(A)及生长后期(B),以荧光灯(FL)作为基础光源,红(R)、蓝(B)LED灯作为补充光源,以A和B时期荧光灯照射为对照(FL),研究了不同补光处理(FLRR(A时期和B时期补充红光)、FLRB(A时期补充红光、B时期补充蓝光)、FLBR(A时期补充蓝光、B时期补充红光)、FLBB(A时期和B时期补充蓝光))对生菜生长及品质指标的影响,以期为人工光环境下蔬菜栽培提供参考依据。结果表明:生长前期补充蓝光更有利于干质量积累,FLBR处理的干质量增长量分别比对照、FLRR和FLRB干质量增长量显著提高27.2%、25.6%和20.3%。在生长前期和生长后期都采用较高蓝光比例的光源,促进了维生素C含量提高,FLBR分别比FLBB处理与对照显著降低12.0%和13.3%;在生长前期和生长后期补充蓝光或红光硝酸盐含量分别比对照显著降低了34.3%、50.8%、37.3%和32.6%。
Romaine lettuce was used as test material,growth stages of romaine was divided into three stages,seedling period,early growth stage（A）and late growth stage（B）,and each period was14 days.Supplemental red（R）,blue（B）LED light based on the fluorescent lamp（FL）was applied during A and B stage.Five treatments were set,the fluorescent lamps applied during A and B（FL）,which was the control;supplemental red light during both A and B period（FLRR）;supplemental red light during A period and supplemental blue light during B period（FLRB）;supplemental blue light during A period supplemental red light during B period（FLBR）;supplemental blue LED light on both A and B period（FLBB）.The growth and nutrition quality parameters of lettuce were determined.The results showed that supplemental light during A period was more impactful than during B period.Supplemental blue light in A period promoted dry biomass to accumulated in B period.Under FLBR treatment,the increase of dry weight was the highest,significantly higher than that of the FL,FLRR and FLRB,respectively 27.2%,25.6% and 20.3%.The vitamin C content of FLBR was significant lower than FLBB and FL by 12.0% and 13.3%.Supplemental red and blue LED light based on fluorescent light was able to respectively decrease the content of nitrate 34.3%,50.8%,37.3%and 32.6%.
