Light environment is one of the indispensable physical environmental factors for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of protected cultivation.
Led plant growth lamp is a kind of lamp with LED (light emitting diode) as the light source. According to the law of plant growth, it must need sunlight, and use light to replace sunlight to give the environment for plant growth and development.
Led plant lamp helps to shorten the growth cycle of plants, because the light source of this lamp is mainly composed of red and blue light sources, using the most sensitive light band of plants. The red light wavelength uses 620-630nm and 640-660nm, and the blue light wavelength uses 450-460nm and 460-470nm. It can promote the differentiation of multiple lateral branches and buds, accelerate the growth of roots, stems and leaves, accelerate the synthesis of carbohydrates and vitamins, and shorten the growth cycle.
A large number of applications of LED in plant protected cultivation environment. The research results show that led plant lamp is particularly suitable for artificial light controlled plant protected cultivation environment.
The color temperature and lumen of artificial light source are seen by biological eyes, while the demand of plants for light is photosynthesis, which does not depend on color temperature and lumen, and is determined by radiation value.
