We know that many plants on the earth cannot grow without sunlight, because plants need sunlight for photosynthesis, and photosynthesis is a physiological function unique to plants. The standard explanation is that green plants (including algae) absorb. Light energy, the process of synthesizing rich organic matter with carbon dioxide (CO2) and water (H2O) while releasing oxygen. The photosynthesis of crops directly affects the production yield and quality of this crop. Therefore, plant photosynthesis research is also an important research topic in the development of high-efficiency agriculture. The use of photosynthesis analyzers for measurement is the most direct. An effective method of measurement.
Photosynthesis is a relatively complicated process. To accurately determine the level of photosynthesis in plants, it is necessary to determine a number of photosynthesis indicators, such as leaf photosynthetic rate, leaf transpiration rate, intercellular CO2 concentration, stomatal conductance, water use efficiency, etc. To obtain these indicator data, the usual steps are to first determine the CO2 concentration, leaf temperature, photosynthetically active radiation, leaf room temperature and humidity, etc., and then scientifically calculate the above photosynthesis index results. The photosynthesis analyzer can quickly and accurately determine the CO2 concentration, leaf temperature, photosynthetically active radiation, leaf room temperature and other parameters, providing a scientific basis for accurate calculation of photosynthesis indicators.
Studies have shown that there is a close relationship between crop yield and quality and crop light energy utilization. According to estimates, in general, only 0.5% to 1.0% of sunlight is used for photosynthesis, while low-yield crops are The utilization rate of light energy is lower, only 0.1%~0.2%, and the utilization rate of light energy in high-yield crops is only 1%~2%. Therefore, it is very large potential to increase crop yield by increasing the utilization of light energy in crops. At present, the measurement and research by means of the photosynthesis analyzer can let us know more about the secrets of crop growth, scientifically guide planting improvement, etc., and help the development of efficient agriculture.
