TECHNICAL FIELD
[0001] The utility model belongs to the technical field of fruit tree production, and particularly relates to a fruit tree branch angle measuring device. BACKGROUND
[0002] The opening angle of a fruit tree not only plays a crucial role in the formation of plant type, but also is one of the important indicators for measuring the spatial distribution ability of the tree. The size of the branch angle can directly affect the morphology and size of the crown, as well as the number of branches, leaves, flower buds, fruits, and light, which are also affected to some extent.
[0003] A fruit tree with a small branch angle can increase the amount of photosynthetic products transported out, thereby causing the tree at a high place to be stronger than that at a low place. A large branch angle can lead to a weakened tree, which is not conducive to nutrient accumulation. In addition, the branch angle is positively correlated with light, and the larger the branch angle, the higher the effective photosynthetic area. Therefore, the size of the branch angle plays a very important role in fruit tree cultivation.
[0004] In fruit tree cultivation, methods such as shaping and pruning, supporting and stretching branches, and spraying plant growth regulators are commonly used to adjust the branch angle. However, in actual production, the branch angle of fruit trees is often adjusted based on human experience, which can result in inconsistent opening angles of fruit trees, either too large or too small, leading to irregular growth of fruit trees and hindering mechanized application. In addition, a large branch angle can cause branch breakage, resulting in economic losses for fruit farmers, while a small branch angle can also affect the photosynthesis of the crown, thereby reducing fruit quality.
[0005] Traditional measurement of the branch angle of fruit trees usually relies on a protractor, but this method has significant limitations. Due to the size limitations of the protractor and the nonlinear growth characteristics of tree branches, it is difficult to achieve high accuracy in measuring the branch angle using a protractor. In addition, although researchers have developed and published a new type of tree branch angle measuring device (Chinese patent 2023109149932), the design of this device is complex, and it needs to be installed for measurement, which is cumbersome and not suitable for large-scale branch angle measurement in the field. On the other hand, previous studies have shown that the zenith angle of a tree branch (i.e., the angle between the tree branch and the horizontal normal) is a more effective method for quantifying the branch angle and is an important phenotypic trait for quantifying ideal plant types. However, the above two measurement methods mainly focus on the angle between the trunk and the main branch, or between the branches, rather than the zenith angle of the branch, which limits the universality and effectiveness of these methods in practical applications.
[0006] Therefore, it is an urgent problem to provide a simple, portable, and accurate measuring device that can directly measure the branch angle (zenith angle) of fruit trees, providing convenience for production. Practical new content
