LED光照對藥用植物生長之影響—以金線蓮為例
LED light on the impact of the growth of medicinal plants - Anoectochilus as an example
摘要
光，對地球上各種物種的生長息息相關。光的應用範圍廣泛，舉凡用於景觀造景、植物培養、醫療保健. . .等等，皆與光有密切的關係。尤其在近幾年，諸多學者將LED應用於植物的照射，並找尋各種波長的光源仿照陽光就可讓植物加速生長，針對不同的植物照射時間與波長就有不同的生長結果。本研究將仿照陽光的波長去照射藥用植物。以人工光源照射，且使用省電與環保的LED燈，利用LED燈的特性，選擇660nm、850nm、940nm波長的光仿造出植物所需要的能量進行照射。以適當時間進行照射就可以促進藥用植物的加速生長，而對植物本身的藥效並不改變。但在環境條件下作物生長階段與營養價值有所不同，所以本研究所要做的事:準確的記錄藥用植物的成長過程，作為實驗研究，找出各種光照方式進而發現新的植物生理與栽培技術，這就是本研究所要做的重點。結果顯示:940nm波長的光能有最佳的助長效果，而850nm波長的光能量對植物生長的幫助則次之，660nm波長的光能量幫助生長的效果最少。

Growth of all species on earth is greatly impacted by the sun light. Sun light has a wide range of applications, such as: landscaping, plant culture, healthcare ... etc., all have a close relationship with the light.Light, especially in recent years, many scholars use LED for illuminating the plants and look for various wavelengths of sunlight can be modeled to allow plant growth. To accelerate the plant growing, we can apply appropriate light on the plant. Generally, the plants in different growth stages will lack certain wavelengths of energy, and artificial light source to make up the lack of sunlight is required. Power-saving and environmentally friendly LED is the best candidate for using as an artificial light. In this study, three different infrared wave length, 660nm, 850nm, 940nm, are been selected to imitate the nature sunlight to light on the medicinal plants to understand the impact on their growth. Amoectochilus herb plant was selected as the studying target. Recording of the growth stages of the medicinal plants as the experimental data, and then found that the new plant Physiology and cultivation techniques are the main tasks of this study. The results showed that: 940nm wavelength of light energy gives the most contribution to help the plant growth, while 660nm gives the least, and 850nm is somewhere between 940nm and 660nm.
