Abstract

The invention discloses an experimental facility and an experimental method for a plant photosynthesis research. The experimental facility comprises a plant rowing device, semiconductor light sources, a first processor, a gas detecting device, a temperature sensor and video gathering modules, wherein the plant rowing device comprises a plurality of growing chambers, each of the semiconductor light sources which are adjustable in wave length and illumination intensity is arranged inside each of the growing chambers, so that each semiconductor light source in each plant growing chamber can directly emit light with wave length or illumination intensity, the wave length or the illumination intensity is needed by each plant growing chamber, and accuracy of a research result is improved. Moreover, the video gathering modules used for gathering videos of plant growth conditions are arranged on the positions of through holes between adjacent plant growing chambers, 360-degree real-time monitoring of plants to be researched in each plant growing chamber is achieved, growth conditions of the plants to be researched under different spectra and illumination intensities can be obtained in a continuous or real-time mode, and reliable data are provided for analysis of the growth conditions of the plants to be researched under different spectra and illumination intensities.

Description

technical field [0001] The invention relates to the field of plant photobiology research, in particular to an experimental device and method for studying plant photosynthesis. Background technique [0002] Photosynthesis is known as the most important chemical reaction on the earth. Without photosynthesis, it is impossible to have the emergence and development of human society. Photosynthesis is the material basis of crop yield formation, how to make full use of solar energy for photosynthesis is a fundamental problem in agricultural production. Photosynthesis is of great significance for improving agricultural productivity and increasing energy production, and it is also very important for studying basic theoretical issues such as the origin of life, evolution, and light energy conversion. Photosynthesis is the uptake of CO from the air by green plants through the stomata of their leaves 2 , and absorb water through the roots, under the action of chloroplasts, use light e...
