摘要

光环境是室内医用大麻（cannabis sativa L.）种植的关键因素。本研究从“当前大麻室内种植照明系统”中选取四种不同光比的流行LED光源，设置四种不同的光周期进行测试。本研究评估了不同光周期和光质量对医用大麻（“汉马11”）大麻二酚（CBD）产量和能量消耗的影响。发光二极管（LED）设置包括12 L (Light):12D (Dark), 14 L:10D, 16 L:8D， 18 L:6D和FR (Far-Red):R (Red):B (Blue):G (Green) = 8:9:3:12 (LED A), FR:R:B:G = 2:4:6:5 (LED B), FR:R:B:G = 1:8:2:3 （LED C）和FR:R:B:G = 1:10:10:1 （LED D）的光比。结果表明：16 L:8D LED A （FR:R:B:G = 8:9:3:12）的大麻CBD总含量、干生物量、单株CBD产量、生产效率和水分利用率最高。研究结果证实，人工调节的光线条件对医用大麻的室内种植有显著影响，不适当的光线设计会降低CBD的产量和能源效率。这项研究为推进医用大麻的室内种植提供了有价值的见解。

Effects of photoperiod and light quality on cannabinoid content and energy use efficiency of medical cannabis

The light environment is a critical factor for the indoor cultivation of medical cannabis (Cannabis sativa L.). In this study, four popular LED light sources with different light ratios were selected from “the current Cannabis Indoor Cultivation Lighting System” and four different photoperiods were set for testing. This study evaluated the effects of varying photoperiods and light qualities on medical cannabis ('Hanma 11') cannabidiol (CBD) yield and energy consumption. The light-emitting diode (LED) settings included photoperiods of 12 L (Light):12D (Dark), 14 L:10D, 16 L:8D, 18 L:6D and light ratios of FR (Far-Red):R (Red):B (Blue):G (Green) = 8:9:3:12 (LED A), FR:R:B:G = 2:4:6:5 (LED B), FR:R:B:G = 1:8:2:3 (LED C), and FR:R:B:G = 1:10:10:1 (LED D). The results showed that 16 L:8D LED A (FR:R:B:G = 8:9:3:12) yielded the highest total CBD content, dry biomass, CBD yield per plant and production efficiency, and water utilization of medical cannabis. The findings confirmed that artificially modulated light conditions have a significant impact on the indoor cultivation of medical cannabis and that inappropriate light design can lower CBD yield and energy efficacy. This study provides valuable insight into advancing the indoor cultivation of medical cannabis.

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
