一、矮化中间砧苹果生产现状及其表现高密度栽植是现代苹果集约化栽培的特点之一,而保证苹果树冠有良好的光照状况,有效地控制苹果过旺的生长和树冠体积是密植成败的关键。自60年代起,研究和利用矮化中间砧,进行矮化密植栽培已成为国内外果树生产发展的一个 First, dwarfing the intermediate anvil apple production status and performance of high density planting is one of the characteristics of intensive cultivation of modern apple, and to ensure that the apple canopy has a good light conditions, effectively control apple over-growth and crown volume is the success or failure of close planting key.
