摘要
光对于植物生长的几乎所有阶段都有着重要影响。为了应对雨雪雾天气、环境污染等导致的自然光不足,各种以人工光照明为基础的设施农业便应运而生。植物生长人工照明主要是从白炽灯开始的,目前最适用于植物生长照明的光源为LED。为此,首先论述光照对于植物生长的影响以及植物生长中对光的吸收特性,着重探讨LED植物生长灯的特性、构成要素,介绍了LED植物生长灯的应用,提出了存在的问题和给出了建议。
Light plays an important role in almost all stages of plant growth. In response to the rain and snow weather, environmental pollution, fog and so on lead to insufficient natural light, artificial-lighting-based protected agriculture arises at the historic moment. Artificial lighting for plant growth mainly starts from the incandescent light bulb. At present the most suitable artificial light source for plant growth is LED. This article discusses the influence of light on plant growth and the absorption characteristics of plant growth light, focuses on the characteristics and constituent elements of the LED plant growth lamps, and presents the applications of growth LED lamps. Besides, the existing problems and suggestions are given.
