The plant canopy structure directly affects many biological and physical processes of the plant, such as photosynthesis, respiration, transpiration, carbon and nitrogen cycling, and precipitation interception. Therefore, the determination of the canopy results of plants is of great significance for improving the modern agronomic level. In general, there are two methods for measuring plant canopy data. The first is direct measurement, and the second is indirect measurement using the canopy analysis system. In modern agricultural research, the second method is used to carry out measurement work. What are the advantages of using canopy analysis to measure canopy data? First of all, let's talk about how direct measurement and indirect measurement are performed. Direct measurement is performed by trying to determine the leaf area of ​​all the leaves, and then calculating the LAI. Since all the tested leaves are to be cut off, most of them are destructive measurements, or at least interfere with the distribution of the canopy and the blade angle, thus affecting the quality of the data. Measuring takes time and effort. Indirect measurement is the use of the quantitative coupling of canopy structure and interaction between radiation and environment in the canopy, canopy analysis system to determine the relevant data of the plant canopy, and to infer LAI through the plant canopy transfer model. The canopy analysis system is related to the canopy structure by processing image data files, such as leaf area index, light gap, and gap distribution. By analyzing the relevant information of the radiation data, the PAR intercepted by the canopy and the radiation level under the canopy can be measured. Therefore, compared with the direct measurement method, using the canopy analysis system to measure the canopy data can avoid the disadvantages caused by the direct measurement method of large-scale destruction of vegetation, and the use of instruments to perform measurement operations is convenient and quick, without time constraints, access to data The advantages of large quantities are very suitable for modern agricultural research and research. Therefore, the canopy analysis system is widely used in the research and teaching of cultivation, breeding, comparison and development of plant groups in agriculture, horticulture and forestry. The actual work has played an important role.
