Abstract
An LED plant growth lamp spectrum, the spectrum including: a light wave of 500-599 nm and a light wave of 700-780 nm, where a ratio of the number of photons in the range of 500-599 nm to the number of photons in the range of 700-780 nm is 0.9-1.6:1. The LED plant growth lamp spectrum promotes indoor cultivation and growth of plants, and helps to increase the yield of medicinal components per unit area and per unit time in the factory production.
