The impact of light on plant growth is very far-reaching. It affects the plant's physiology, ecology, and the benefits of agricultural production to varying degrees. In general, when the light is sufficient, the crop grows better and the production capacity is stronger. Insufficient illumination will directly affect the growth of crops and lead to plant wilting or death. Therefore, in agricultural research, light is an important environmental factor affecting plant physiology. Photosynthetically active radiation values ​​can be measured using photosynthetically active radiation recorders. found out.
In the photosynthesis of plants, light is mainly used as an energy substance to participate in the growth of plants. However, for plant growth, only light that can be absorbed and utilized by plants is beneficial to the photosynthetic and dry matter accumulation of plants. Therefore, in agricultural production, Research light cannot be used to determine total photosynthetic radiation, but to measure photosynthetically active radiation. This has been widely recognized and adopted, and in order to better facilitate the development of photosynthetically active radiation measurements, Topsun Yunnong R&D and production A professional measuring instrument, the photosynthetic active radiation recorder, enables researchers to rapidly obtain photosynthetically active radiation of sunlight in the 400-700 nm wavelength range in the terrestrial environment. Currently, the photosynthetic active radiation recorder has been widely used in agricultural meteorology. And crop growth research and other fields.
In modern agricultural research, measuring instruments such as photosynthetically active radiation recorders are becoming more and more widely used. People are willing to use them and actively use them. Of course, because the instrument has advantages that are unmatched by traditional measurement methods, measurement efficiency and accuracy There will be significant improvements. Taking the photosynthetic effective radiation recorder as an example, the main features of the instrument are its small size and portability; Chinese LCD screen display, friendly man-machine interface; manual acquisition or free time interval acquisition, and excellent performance. It not only measures accurately, is easy to use, but also has good stability and maintenance-free. Therefore, using it in actual work can make research work more effective and obtain better research results.
