摘要
为了探究f式树形对简易单栋拱棚避雨栽培'阳光玫瑰'葡萄光合特性及果实品质的影响,以Y式、T式树形为对照,分析了 f式树形4年生'阳光玫瑰'葡萄叶幕冠层结构和光能截获面积、叶片叶绿素含量、光合能力、果实品质和产量等指标.结果表明:简易单栋拱棚避雨栽培条件下,f式树形在增加叶片实际光能截获面积、提高叶片叶绿素含量、增强叶片光合作用、改善果皮色泽、提高果实品质和产量等方面表现出相对优势.
Abstract
In order to investigate the effects of f-shaped tree shape on photosynthetic characteristics and fruit quality of'Shine Muscat'grapevines under simple single arch shed,the four-year-old'Shine Muscat'grapevines were used as experimental material,and Y-shaped and T-shaped trees were used as the control.The canopy structure,light energy interception area,leaf chlorophyll content,leaf photosynthetic capacity,fruit yield,and fruit quality off,Y,and T-shaped tree shape were measured.The results showed that the f-shaped tree shape has advantages in terms of increasing in the actual light energy interception area,chlorophyll content and photosynthesis of the leaves,and improvement in the fruit yield,fruit quality,and color of the peel under simple single arch shed in comparison with Y and T-shaped tree shape.
