The use of plant transpiration rate tester to determine the transpiration rate of plants is an important means to study the water and drought resistance of plants from the perspective of plant physiology, and this approach is more closely related to the actual physiological conditions of plants, so it can better reflect the plant The actual consumption of water and water demand, so with the development of science and technology and plant physiology research continues, the plant transpiration rate tester this more convenient, scientific and accurate measurement equipment is naturally more favored by agricultural science and technology workers. The application of agricultural research is also becoming more and more extensive.
For a long time, agricultural researchers have paid much attention to the study of plant transpiration. Therefore, there are many methods for measuring and studying the transpiration rate of plants. The plant transpiration rate analyzer is widely used as a scientific instrument in recent years. method. In addition, methods to determine the transpiration rate of plants include leaf chamber method and gas exchange method. However, these traditional detection methods often have some deficiencies and drawbacks. For example, the leaf chamber method is one of modern tree evapotranspiration. However, there are two major flaws. One is that the measurement conditions deviate from the natural environmental conditions and errors are generated. The second is that the sampling unit is too small and the representativeness is declining, which leads to serious deviations in the measurement results during scale development. The gas exchange law may cause transient stimulation of the stomata due to the introduction of dry air, and the interfacial layer resistance in the leaf chamber is relatively small, thus resulting in a high measurement value of the method.
The plant transpiration rate tester has obvious advantages compared with traditional measurement methods. Firstly, the use of the plant transpiration rate tester is very convenient. It is small in size, light in weight, easy to carry, and can be operated by a single person. Therefore, its application The scope of the wide range, can be determined for different types of leaves, a variety of plants in different shapes of the leaves to be measured, followed by the plant transpiration rate meter can simultaneously perform a variety of parameters such as leaf temperature, air temperature and humidity, photosynthetically active radiation Strength and other indicators, and then calculate the plant transpiration rate, increased the representativeness of the measurement, is a very scientific measurement of plant transpiration rate.
