Ⅱ、提高果实质量的主要技术途径已如前述,影响苹果果品质量的因素是多方面的。其中,最主要的是品种的遗传特性、适宜生态条件的选择,以及由品种遗传特性和生态条件为依据的综合栽培技术体系。这几个方面,也应该是提高苹果果品质量的最重要的技术途径。一、品种选择与品种改良栽培品种,是苹果生产的最基本、最重要的生产资料。从一定意义上讲,栽培品种选择的适宜与否,对苹果的产量水平、品质好坏,和收益高低等,都起着长远的、决定性的作用。因此,选择、利用优良的栽培品种,是实现苹果优质、丰产、增加经济效益的极 Ⅱ, the main technical ways to improve the quality of fruits As mentioned above, the factors that affect the quality of apple fruit are many. Among them, the most important are the genetic characteristics of varieties, the choice of suitable ecological conditions, and the comprehensive cultivation system based on the genetic characteristics and ecological conditions of the cultivars. These aspects, should also be the most important technical ways to improve the quality of apple fruit. First, the choice of varieties and varieties of cultivated varieties of improvement, is the most basic and most important production means of apple production. In a certain sense, the appropriate selection of cultivars will play a long-term and decisive role in the output level of apples, the quality of the apples and the level of returns. Therefore, the choice, use of fine varieties of cultivated apple is to achieve high quality, high yield, increase economic efficiency of the very
