AI Technical Summary
现有的补光技术对柑桔幼苗生长的促进效果远未达到理想水平，如何精准、高效地调控柑桔幼苗生长，是本领域亟需解决的技术问题
[0018] (1) This invention regulates the morphogenesis, material accumulation, and distribution of citrus seedlings through nighttime supplemental lighting. In terms of morphology, L... 432 It can significantly improve aboveground indicators such as plant height and leaf number, while also promoting the increase of root-related parameters, resulting in optimal overall performance; L 454 L 445 It can effectively promote plant height and leaf development, L 650It is beneficial for thickening and widening the leaves, L 520 It can significantly promote root elongation but inhibit stem thickening, L 550 L 665 The overall promoting effect is relatively weak. Regarding material accumulation, L... 432 It can significantly improve the fresh and dry weight of roots, stems, and leaves, and has the strongest ability to accumulate substances; L 454 L 650 White light can significantly increase dry matter accumulation, while L... 520 L 550 It has an inhibitory effect on biomass accumulation. Correlation and principal component analysis showed a high positive correlation between aboveground indicators, with root growth significantly driving aboveground development. 432 The overall score was much higher than other treatments, making it the best monochromatic light for promoting the overall growth of orange seedlings.
