色光法利用特定波长的光对作物进行特别的照射，可明显促进作物的生长，改变作物的营养成分。如对结果作物用红色光定期照射，结果这些作物的果实成熟速度明显加快，果实的糖份、维生素C和某些微量元素也有明显增加。俄罗斯的别尔姆农场利用红色光定期照射西红柿和黄瓜，使它们 Shade method using a specific wavelength of light on the crops for special irradiation, can significantly promote the growth of crops, changing the nutritional content of crops. If the results of crops with red light on a regular basis, the results of these crops significantly faster fruit ripening, fruit sugar, vitamin C and some trace elements also increased significantly. The Belem farms in Russia use red light to regularly irradiate tomatoes and cucumbers to make them
