Background

Plant lamp is more and more widely used in the artificial cultivation field, because different plants are different to the light demand of plant lamp, and even the same plant is different to the demand of light at different growth stages. Scientific experiments prove that light with different wavelengths has different influences on plant growth. Blue-violet light and cyan light in visible light have great effects on plant growth and formation of buds, and the light can inhibit the elongation of plants to form short and thick shapes, and the blue-violet light is the most important light for dominating cell differentiation; bluish violet light also affects the phototropism of plants. The ultraviolet ray inhibits the formation of some growth hormone in the plant body, thereby inhibiting the elongation of the stem; ultraviolet light also causes phototropic sensitivity and promotes the formation of anthocyanins, as does blue, violet and cyan light in visible light. Both red light in the visible and infrared light in the invisible spectrum promote germination of seeds or spores and elongation of stems. Red light can also promote the decomposition of carbon dioxide and the formation of chlorophyll.
