GB/T 32655-2016 Terms and definitions for LED lighting for plant growth
3 Terms and definitions
The terms and definitions defined in GB/T 32655-2016 apply to this document:
4 Overview
Light is one of the most important environmental factors for plant growth: It is not only the energy source for plant growth and development, but also the key to plant morphology:
The energy that plants rely on for survival comes from sunlight: Photosynthesis is an important biological way for plants to capture light energy:
Fixing carbon dioxide through photosynthesis to synthesize organic matter and produce oxygen is one of the decisive factors for the continuation of life on Earth:
As a new type of light source, LED has the characteristics of energy saving, environmental protection, long life, and short response time, and has obvious advantages in the field of agricultural lighting:
First, compared with traditional light sources, LEDs can adjust factors/parameters such as spectrum and radiation intensity according to demand; second, the heat generated by LEDs
Low, can be close to the plant without causing plant tissue burns; secondly, the LED light source is small in size and is more suitable for multi-layer three-dimensional combination planting
The cultivation system helps to reduce the height of the cultivation shelves and increase the number of plants cultivated per unit space:
It has attracted widespread attention and is widely used in all-artificial light plant factories and greenhouse supplementary lighting production to achieve the purpose of increasing yield and improving quality:
This document focuses on the LED artificial light environment for plant growth, introduces the elements of plant growth light environment, plant photosynthesis and light-controlled growth and development
As well as the light demand characteristics of plant growth, the key indicators of plant growth light response are proposed, and the effects of plant growth on LED artificial light sources are analyzed:
The requirements and key elements of artificial light environment lighting design are used to guide the scientific and reasonable evaluation of LED artificial light environment for plant growth:
5 Elements of light environment for plant growth
5:1 Overview
Plants' demand for light is mainly reflected in four aspects: spectrum, light intensity, photoperiod and light distribution, which are also called the "halo" of plant growth:
Environmental factors": The light environment affects and
Regulating plant growth and understanding the impact of light on plant growth are the theoretical basis for the application of artificial light sources in agricultural production:
