苹果树盛果期的形态特征是:树冠体积最大,结果最多。枝条生长量逐年减少,树势不稳。枝不成组而紊乱,枝组易衰而结果外移,大年果多而个小,小年果少而枝弱。此期的生理特点是:营养生长和生殖生长由相对平衡而逐步转向以生殖生长为主;养分的消耗与积累由相对平衡而逐渐转向消耗大于积累。依据其形态特征及生理特点对此期苹果树管理总起来讲是:树到成龄讲修剪,结果枝组是重点。一、树势的调整树势的强弱是树体营养水平和生长与结果状况的综合表现,是修剪、水肥管理等技术实施的重要依据。通过调查认为:1.盛果期的苹果树一般发育枝的年总生长量在300～450米左右,每条发育枝年平均生长量为45～50厘米左右,中、长果枝占果枝总数的
Apple tree full fruit period morphological characteristics are: the largest crown, the largest result. Shoot growth decreased year by year, tree instability. Branches are not grouped and disorder, the branch group is easy to decline and the results of the relocation, the New Year more than a small, small fruit and young branches weak. The physiological characteristics of this period are: vegetative and reproductive growth gradually shifted from relative equilibrium to reproductive growth; nutrient consumption and accumulation gradually shifted from consumption to accumulation over accumulation. According to its morphological characteristics and physiological characteristics of the management of apple tree in this period is always speaking: tree to mature age, the result of the branch group is the key. First, the adjustment of the tree vigor The strength of the tree is the overall performance of tree nutrition and growth and the results of the situation, pruning, water and fertilizer management and other technical implementation of the important basis. Through the investigation, it is concluded that: 1. The annual total growth of apple trees in developing stage is about 300-450 m, and the average annual growth of each developing branch is about 45-50 cm.
