一种发光二极管(LED)系统,涵盖了从紫外线到远红辐射(360至760nm,“白色”光谱)进行了研究,用于胸腺的温室生产。检查了生物质产量和萜类化合物的含量,并确定了灯的生产率和电效率。在柏林的秋季和冬季,在自然低辐照条件下,将所有结果与两种常规使用的灯具类型(高压钠灯(HPS)和荧光灯(FL))进行了比较,德国。在LED下,胸腺的发育高度加速,与HPS和FL相比,每平方米的新鲜产量分别增加了43%和82.4%,分别。与HPS和FL照明系统相比,在LED下,每平方米干产量也增加了43.1%和88.6%。虽然萜类化合物的组成不受影响,与FL相比,在LED和HPS下,每克叶干物质的数量显着增加。Further,功耗计算显示,LED和FL的节能分别为31.3%和20.1%,分别,与HPS相比。总之,在自然光照不足的条件下,广谱LED系统的实施具有巨大的潜力,可以增加胸腺的数量和质量,同时显着降低能耗。
A light-emitting diode (LED) system covering plant-receptive wavebands from ultraviolet to far-red radiation (360 to 760 nm, \"white\" light spectrum) was investigated for greenhouse productions of Thymus vulgaris L. Biomass yields and amounts of terpenoids were examined, and the lights\' productivity and electrical efficiency were determined. All results were compared to two conventionally used light fixture types (high-pressure sodium lamps (HPS) and fluorescent lights (FL)) under naturally low irradiation conditions during fall and winter in Berlin, Germany. Under LED, development of Thymus vulgaris L. was highly accelerated resulting in distinct fresh yield increases per square meter by 43% and 82.4% compared to HPS and FL, respectively. Dry yields per square meter also increased by 43.1% and 88.6% under LED compared to the HPS and FL lighting systems. While composition of terpenoids remained unaffected, their quantity per gram of leaf dry matter significantly increased under LED and HPS as compared to FL. Further, the power consumption calculations revealed energy savings of 31.3% and 20.1% for LED and FL, respectively, compared to HPS. In conclusion, the implementation of a broad-spectrum LED system has tremendous potential for increasing quantity and quality of Thymus vulgaris L. during naturally insufficient light conditions while significantly reducing energy consumption.
