Abstract:
The Hong Kong ‘Iceberg’ lettuce was used as the test material,the effect of light intensity and photoperiod on the growth，quality and element utilization efficiency of lettuce in closed plant factory were studied.There were 4 light intensity levels (150,200,250,300 μmol?m-2?s-1) and 3 photoperiod levels(8 h?d-1，12 h?d-1 and 16 h?d-1) were set up.The results showed that the growth of lettuce leaves could be promoted by increasing light intensity and prolonging light within 30 days after transplanting.The growth was the best when the photoperiod and light intensity were 16 h?d-1 and 300 μmol?m-2?s-1.On the 30-40 day，the growth of lettuce leaves was optimal on condition that the photoperiod and light intensity were 16 h?d-1 and 278.67 μmol?m-2?s-1 respectively.As the increase of light intensity，soluble sugar，soluble protein and carotenoid content increased，but nitrate and vitamin C content decreased，then presented a increasing trend.The longer photoperiod contributed to synthesize soluble sugar，soluble protein，vitamin C and carotenoids，but depress nitrate，moreover，the principal component analysis showed that 300 μmol?m-2?s-1 and 16 h?d-1 were most beneficial to lettuce quality.In all growth stage，powerful beam and longer photoperiod could increase the utilization efficiency of N and P elements，but were not conducive to the utilization of K.In the first growth stage，the utilization N and P were the most efficient，but K was at the later latter stage.Comprehensive analysis showed that increasing light intensity and prolonging light time were beneficial to growth at first 30 days，but light intensity at 278.67 μmol?m-2?s-1 was beneficial to growth at later growth stage.In addition，it′s conducive to the element utilization of N，P and lettuce quality to increase light intensity and prolong photoperiod.
