Light environment is one of the indispensable physical environment factors for plant growth and development. It is an important technology in the field of protected cultivation to control the formation of plant morphology through light quality regulation.
Scientific choice of light source can better grasp the speed and quality of plant growth. When using artificial light source, we must choose the natural light closest to the photosynthesis condition of plants. Measure the photosynthetic flux density (PPFD) produced by light source on plants, master the rate of photosynthesis and the efficiency of light source, and the light quantity of photosynthetic effective photon starts the photosynthesis of plants in chloroplasts: including light response and continuous dark response.
Plant growth lights should have the following characteristics:
1. Efficiently convert electric energy into radiant energy.
2. Achieve high radiation intensity within the effective range of photosynthesis, especially low infrared radiation (thermal radiation)
3. The radiation spectrum of the light bulb meets the physiological requirements of plants, especially in the effective spectral region of photosynthesis.
