Embodiment 1

[0052] Embodiment 1, pruning evaluation based on apple tree canopy illumination calculation

[0053] For orchards under the same management mode, apple trees with the same (similar) tree species, tree age, and tree shape are a group. Each group of apple trees chooses one tree as the sample tree, and the apple trees other than the sample tree are recorded as the trees to be tested.

[0054] The pruning evaluation of the tested trees in the orchard is based on the sample trees.

[0055] In the process of implementation, the data of two adjacent years of sample trees are used, and the data of the first year is used as a reference in the second year to evaluate the light conditions after pruning.

[0056] Such as figure 1 As shown, the pruning evaluation based on the apple tree canopy illumination calculation is carried out in the following steps:

[0057] 1. Trimming and evaluating the first two years (2014) of the current year (2016)

[0058] Set up a sample tree in the fiel...

Abstract

The invention provides a pruning evaluation method based on fruit tree canopy illumination calculation. The method includes: in each of the two years in the first N years of the pruning evaluation year, after the same spring pruning and germination of the sample tree and the tree to be tested, the three-dimensional point cloud data of the sample tree canopy are obtained in different position cubes The number of box counting dimensions in the grid and the light intensity or relative light intensity in each of the cube grids of the sample tree in the stable period of the leaf curtain establish a mathematical model; the leaf curtain of the tree to be measured in the current year is predicted and pruned by the mathematical model The results of light intensity or relative light intensity distribution in the stable period can be used to evaluate whether the fruit trees are pruned reasonably. The method has the advantages of rapidity, convenience, reasonable calculation method, high accuracy, and is suitable for automatic programming, and can also greatly improve operation efficiency and reduce labor intensity of operators.

Description

technical field [0001] The invention relates to a pruning evaluation method based on calculation of fruit tree canopy illumination and facilitating the result. Background technique [0002] Fruit tree shaping and pruning, as an important technology in the implementation of comprehensive management, is generally valued by the majority of fruit farmers and scientific and technological workers. To a large extent, it can reasonably adjust the relationship between fruit tree growth and fruiting, and affect the formation of yield and quality. It is the main technical means to obtain high-quality and efficient tree structure. Pruning can also provide convenient conditions for various field operations. [0003] Through scientific and reasonable pruning, the distribution, transportation, accumulation and digestion of nutrients and hormones can be re-adjusted, the relationship between fruit trees and the surrounding environment can be changed, the balance between various parts of frui...
