科学家们发现,农作物对色彩有强烈的反应,特别是体现在对阳光的吸收上。 不同的农作物往往还会表现出对红橙黄绿青蓝紫七种色光所构成的太阳光中某种色光的偏好。其中红、黄、蓝、紫四种色光最受欢迎,光合作用的效率也最高。农作物对绿色光往往“同性相斥”,几乎全部反射掉。具体到每一种农作物,又各有不同。例如:小麦在蓝、紫色光照射下发育最快,蛋白质含量也会增加;甘蔗等糖料作物在红色光的照射下,含糖量会大大增加;胡萝卜在红黄色的混合光照射下生长最快;辣椒对色光并不怎
Scientists have found that crops respond strongly to color, especially in the absorption of sunlight. Different crops tend to exhibit a preference for a shade of sunlight in the seven colors of red, yellow, green, blue and violet. One of the red, yellow, blue, purple four kinds of color light is the most popular, photosynthesis efficiency is also the highest. Crops tend to “gay” with green light, reflecting almost all of them. Specific to each crop, but also different. For example, wheat grows fastest and its protein content increases under the irradiation of blue and purple light. The sugar content of sugarcane and other sugar crops will greatly increase under the irradiation of red light. The carrot grows under the mixed light of red and yellow Fast; pepper on the shade is not how
