Abstract

This thesis aims to explore the effects of different spectral distributions on the photosynthetic rate of plant leaves. By selecting specific plant species, different spectral conditions such as red light, blue light and mixed light were set under controlled conditions, and the leaf photosynthetic rate was measured using a gas exchange analyzer. The results showed that different spectral distributions significantly affected the photosynthetic efficiency of plant leaves. Specifically, plants showed a higher photosynthetic rate under red light conditions, while blue light inhibited the photosynthetic rate of leaves. The results under mixed light conditions were between the two. This study provides experimental data support for a deeper understanding of the effects of spectral distribution on plant growth and its photosynthetic mechanism, and has certain guiding significance for the optimization of the light environment in agricultural production.
