For fruit growers, not only do they need to pay attention to the production of orchard planting, but also need to care about the quality of the fruit, because both of these are related to the actual income of fruit tree cultivation, and to achieve the goal of good fruit quality and high yield, it needs to be clear Which factors are related to them, so the use of plant canopy analysis to study the relationship between canopy structure and fruit quality can help to adopt scientific measures to improve the quality of fruit and achieve greater economic value in fruit cultivation.

In most of the pear-planting regions of China, pear-tree plasticity has been used to increase yield, but it has overlooked the impact of fruit tree canopy structure on fruit quality, so the actual result is the poor ventilation and light transmission conditions of the crown. Yields are stagnant and fruit quality is poor. Therefore, in order to improve this situation, people can use plant canopy analysis to study the relationship between canopy structure and fruit quality, hoping to provide theoretical or technical basis for fruit tree shaping and construction research.
The pear variety used in the experiment was a horizontal step-style Fengshui pear, which was seven years old. The control fruit was an ordinary orchard and evacuated and layered. The plant canopy analyzer was used to study the canopy structure characteristics of pear tree and its relationship with its quality was analyzed. The analysis included tree structure analysis, canopy analysis and fruit quality analysis. The analysis and research results show that the horizontal step type of Fengshui pear canopy aperture, the quantum light flux density under the canopy scattered light. The mean dip angle is also significantly higher than that of the evacuation layered shape; the photosynthetic photon flux density and the total photosynthetic photon flux density under the canopy are 1.83 and 1.76 times that of the evacuation layered shape, respectively. Therefore, compared with the evacuation of large crowns, the horizontal stepped tree structure is distinct, the canopy opening is large, the total photon photon flux density of the canopy is high, and the good tree structure and the total length of the vegetative shoots may be horizontally-stepped pears. The reason for the excellent fruit quality.
