不同树形对设施桃冠层特性、光合特性及果实品质的影响
Effects of different tree shapes on the canopy characteristics,photosynthetic characteristics and fruit quality of peaches in greenhouse
摘要
Abstract
Using the three-year-old'Zhongnong jinhui'as the test material,the differences in canopy characteristics,photosynthetic characteristics and fruit quality among the multi-branch cluster shape,Y-shaped and main trunk shape of the three pruning methods under the greenhouse cultivation mode were explored,to provide a reference for tree shape selection in greenhouse peach cultivation.The results showed that there was no significant difference in the transmission coefficient,gap fraction and leaf area index among the three tree shapes in the young fruit stage,expansion stage and mature stage.The photosynthetically active radiation of the multi-branch cluster shape was the lowest in the young fruit stage,while that of the main trunk shape was the highest in the mature stage.Combining the photosynthetic index performance in the young fruit stage and the mature stage,the ranking of photosynthetic characteristics of the three tree shapes was multi-branch cluster shape＞main trunk shape＞Y-shaped.There was no significant difference in fruit quality between the multi-branch cluster shape and the main trunk shape,both were better than the Y-shaped.The yield of the Y-shaped and the main trunk shape was comparable and significantly higher than that of the multi-branch cluster shape.The fruit quality and photosynthetic performance of the lower layer of the Y-shaped were the worst.Considering both fruit quality and yield,the main trunk shape was the best tree shape under the tested conditions.关键词
