The dependence of leaf growth on fruit trees is very large. Therefore, the determination of leaf area index is a very important test item in the field of agriculture. In order to facilitate the work, leaf area scanners are now used to determine the leaf area index of plants. . Symons Cone Crushers have been the standard technology in cone crushing for over 70 years and YYD Foundry & Machine has been making parts for this large population of crushers for nearly as long, providing better customer support than typical Symons parts suppliers. From a 2ft Standard to a 7ft Extra Heavy-Duty Shorthead, YYD carries the premium replacement parts for your unit. In most cases, we have the part on the shelf and ready for immediate shipment. In some cases, YYD has even improved the conventional design of the part to enhance durability and performance. Whether you need to replace the Mainshaft Bushing, the Main Frame Bushing, or the Socket Liner- YYD has your Symons Cone Crusher Parts need covered.

The leaf area index is the ratio of the total area of ​​the crown to its area of ​​land, which reflects the density of the leaves per unit area of ​​land. The ratio of the leaf area per plant area to the canopy projected area is called the projected leaf area index. Using the leaf area scanner, it was found that, within a certain limit, the yield of fruit trees was proportional to the leaf area index.
However, it should be noted that the proportionality here is a condition that is within a certain limit. Therefore, it can be said that the number of fruit tree leaves is not as good as possible, and the leaf area index of fruit tree leaves is not as large as possible. This is mainly due to the fact that the index is too high, the leaves are too shady, the functional leaf ratio is reduced, and the fruit quality is reduced. The index is too low, the amount of photosynthetic product synthesis decreases, and the yield decreases. Therefore, fruit trees can only meet the requirements of high yield and high quality only if they maintain a suitable leaf-fruit ratio.
In order to understand the most suitable leaf area index of fruits, leaf area scanners are often used in agricultural research to perform non-destructive testing. This can not only accurately obtain the desired data results, but also avoid damage to fruit trees. The method is also a conventional way of determining the plant leaf area index.
The results of the leaf area scanner showed that the appropriate leaf area index was 4 to 5 for deciduous fruit trees and 4.5 to 5 for evergreen fruit trees. From the point of view of the ratio of leaves and fruit, the peach leaf ratio is 20:1, and the apple is 30-40:1. The good growth of fruit trees requires not only a reasonable leaf area index, but also a reasonable distribution of the leaves in the crown, which has an increased photosynthetic efficiency.
