术语“人工照明植物工厂”指的是一种受控环境，通过在小范围内有效利用水、养分和劳动力，能够生产出产量高、质量高的无农药植物(Merrill等人，2016)。为创造最佳条件而控制的条件和投入使全年生产成为可能(Yamori等人，2014年)。在许多亚洲、欧洲和北美国家，植物工厂被用于商业生产绿叶蔬菜、草药和幼苗(Hayashi，2016)。然而，这项技术仍在开发中，需要在建筑和劳动力成本、电力使用、产量和质量以及光源的高效利用方面进行改进，例如荧光灯和发光二极管(LED)(Kozai，2013)。目前，通过使用多个培养架和集约化栽培模式，利用LED来管理绿叶蔬菜的生产，但树冠遮蔽外部叶片会降低光合作用速率，加速外部叶片的衰老，在包装和运输之前必须修剪外部叶片，导致产量损失超过10%(Zhang等，2015；Kozai和Niu，2016)。光合作用是植物生长和生产力的基础(Yamori，2016；Yamori和Shikanai，2016)。光是影响植物生长的最重要的环境因子之一，不仅是光合作用的基本驱动力，也是植物生长发育的重要调节因子(Terashima et al.，2006)。低光强限制了光合作用速率，如果光强低于补偿点(即光合作用速率为零的PPFD)，碳就会损失。弱光还会触发叶片衰老，导致产量损失(Frantz等人，2000年)。超过90%的作物生物量来自光合作用产物，因此叶片光合作用的增强应该会增加产量(Long等人，2006；Yamori等人，2011；2016)。除了光强，光质也极大地影响光合作用和植物生长(McCree，1971；Inada，1976；Lin等人，2013)。80%至95%的蓝光和红光被广泛植物物种的叶片中的叶绿素吸收(Terashima等人，2009年；Muneer等人，2014年)。红光促进光合作用，诱导下胚轴伸长和叶面积扩大；蓝光调节叶绿素生物合成，抑制细胞伸长(McNellis和邓，1995；han等，2017)。在大豆(Guiamet et al.，1989)和向日葵(Rousseaux et al.，1996)中应用红光可以抑制叶片衰老，在小麦中应用蓝光(Causin et al.，

The term “plant factory with artificial lighting” refers to a controlled environment that enables the production of pesticide-free plants with high yield and quality through the efficient use of water, nutrients, and labor within a small area (Merrill et al., 2016). Controlled conditions and inputs to create optimal conditions enable year-round production (Yamori et al., 2014). In many Asian, European, and North American countries, plant factories are used for commercial production of leafy greens, herbs, and seedlings (Hayashi, 2016). However, the technology is still being developed, and improvements are needed in construction and labor costs, electricity use, yield and quality, and the efficient use of light sources, e.g., fluorescent lamps and light-emitting diodes (LEDs) (Kozai, 2013). Currently, the production of leafy greens is managed with LEDs through the use of multiple culture shelves and an intensive cultivation pattern, but shading of outer leaves by the canopy reduces photosynthetic rate and accelerates the senescence of the outer leaves, which have to be trimmed before packaging and shipment, resulting in yield losses of over 10% (Zhang et al., 2015; Kozai and Niu, 2016). Photosynthesis underlies plant growth and productivity (Yamori, 2016; Yamori and Shikanai, 2016). Light is one of the most important environmental factors that influence plant growth, and is not only the basic driving force of photosynthesis, but also an important regulator of plant growth and development (Terashima et al., 2006). Low light intensity restricts the photosynthetic rate, and if the light intensity falls below the compensation point (i.e., the PPFD at which photosynthetic rate is zero), carbon is lost. Low light also triggers leaf senescence, resulting in yield loss (Frantz et al., 2000). More than 90% of crop biomass is derived from photosynthetic products, so the enhancement of leaf photosynthesis should increase yield (Long et al., 2006; Yamori et al., 2011; 2016). As well as light intensity, light quality greatly affects photosynthesis and plant growth (McCree, 1971; Inada, 1976; Lin et al., 2013). 80 to 95% of blue and red light is absorbed by chlorophyll in leaves across a broad range of plant species (Terashima et al., 2009; Muneer et al., 2014). Red light promotes photosynthesis and induces hypocotyl elongation and leaf area expansion; blue light regulates chlorophyll biosynthesis and suppresses cell elongation (McNellis and Deng, 1995; Han et al., 2017). Leaf senescence can be suppressed by the application of red light in soybean (Guiamet et al., 1989) and sunflower (Rousseaux et al., 1996), and of blue light in wheat (Causin et al.,
