LED光照对大麻素积累的影响及大麻种植人工光照系统设计探讨

Discussion on the Effect of LED Light on Cannabinoid Accumulation and the Design of Artificial Lighting System for Hemp (Cannabis Sativa L.) Cultivation

随着欧美一些国家大麻种植合法化,植物光照海外市场迎来的爆发期,2020年我国LED植物光照产品的出口市场呈现迅猛增长。LED以其高效节能和光谱可控等特点,已经应用于大麻种植领域。本文介绍了大麻的植物学特点、大麻素、大麻的分类与应用,通过对国内外相关研究的分析,重点阐述光合光子通量密度(PPFD)、光质、光周期对大麻生长发育和大麻素积累的影响,提出相关建议和思考,最后探讨LED人工光照系统的设计方法。

With the legalization of cannabis cultivation in European and American countries, the plant has ushered in an outbreak period in overseas markets. In 2020, the export market of China’s LED plant lighting products showed rapid growth. LED has been applied in the field of cannabis cultivation due to its high efficiency, energy saving and controllable spectrum. This article introduces the botanical characteristics of cannabis, the cannabinoids and the classification and application of cannabis. Through the analysis of relevant research at home and abroad, it focuses on the effects of photosynthetic photon flux density(PPFD), light quality, and photoperiod on the growth and development of cannabis and cannabinoid accumulation, then puts forward relevant suggestions and considerations. Finally, the design of LED artificial lighting system is discussed.
