宁夏是解放后才发展的苹果新区,目前苹果单产大大低于全国水平,努力提高单产是发展我区苹果生产的一项重要任务.提高单产的措施很多,其中之一是树体结构的合理性.为此,我们于1979～1981年在全区16个国营园艺场(队)和两个社队果园,对苹果主栽品种(结果大树及少数8～10年生果树)的树体结构进行了初步调查,现将结果整理如下: 一、树形宁夏苹果基本上采用三主枝邻近半圆树形,即基部具有三个主枝,全部主枝(六、七个)在中干上成疏散的层性排列,到一定的株高再落头开心.
Ningxia is an apple-growing new district after the liberation, at present, the yield of apple is much lower than the national average level and efforts to improve yield are an important task in developing apple production in our district. There are many measures to improve yield, among which is the rationality of tree structure To this end, we carried out the tree structures of apple cultivars (fruiting trees and a few 8-10 year old fruit trees) in 16 state-owned horticultural fields (teams) and two commune orchards in the region from 1979 to 1981 A preliminary survey, the results are now organized as follows: First, the tree Ningxia apple basically uses three main branches near the semicircular tree, that the base has three main branches, all the main branches (six or seven) in the trunk into the evacuation The arrangement of layers, to a certain height and then happy.
