Problems solved by technology

Under such conditions, the actual light received by the leaves becomes more complicated. Only by measuring the intensity of incident light, no matter whether it is single-sided or double-sided, cannot accurately reflect the actual light received by the leaves, which has become a complex research. Technical bottleneck of photosynthesis measurement equipment under light conditions
For scientific research equipment with high precision requirements, it will seriously affect its application effect and application value.

Abstract

The invention discloses a method and device for accurately measuring the light intensity of a double-side lighting blade. The method includes the steps that S1, the intensity of incident light between a first measuring light source and one side of the blade is measured; S2, the intensity of emitted light generated after the first measuring light source penetrates through one side of the blade is measured; S3, the intensity of incident light between a second measuring light source and the other side of the blade is measured; S4, the intensity of emitted light generated after the second measuring light source penetrates through the other side of the blade is measured; S5, the intensity of actual light received by the blade is calculated according to the steps from S1 to S4. The method and device can meet the requirement for measuring the two sides of the blade and can accurately reflect the actual lighting intensity of the blade, and accordingly measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of plant physiological analysis, in particular to a method and device for accurately measuring the light intensity of double-sided light-receiving leaves. Background technique [0002] Photosynthesis is light energy synthesis, which means that green plants, animals and some bacteria containing chloroplasts undergo light reaction and carbon reaction (formerly known as dark reaction) under the irradiation of visible light, and use photosynthetic pigments to convert carbon dioxide (or hydrogen sulfide) The biochemical process of converting water into organic matter and releasing oxygen (or hydrogen) is also the most important chemical reaction in plant physiological metabolism. The measurement and research of photosynthesis has always been a hot spot in the fields of plant physiology, plant ecology, agronomy, forestry, horticulture, and algal physiology and ecology. [0003] The photosynthesis of plants is aff...
