光合产物是构成果树产量的主要因素,因而提高果树的光合效能,对果树产量和品质有决定性影响。目前国内外果树生产上栽培制度和栽培技术,也都围绕提高果树光合效应而在变化,并相应地加强果树光合作用的研究。一、果树叶片的光合类型1、高效叶:这类叶有较大面积,色浓绿、厚,角质层发达,叶内栅栏组织发达, Photosynthetic products constitute the main factors of fruit tree yield, thus improving the photosynthetic efficiency of fruit trees, have a decisive impact on the yield and quality of fruit trees. At present, the cultivation system and cultivation techniques of fruit trees both at home and abroad are also changing around the enhancement of photosynthesis of fruit trees and correspondingly, the research of photosynthesis of fruit trees is strengthened. First, the photosynthetic type of fruit tree leaves 1, efficient leaves: This kind of leaves have a larger area, dark green thick, thick, cuticle developed, leaf palisade tissue developed,
