苹果是果树中的主要树种,栽培广,产量高,品质好,耐贮藏和运输,很久以来就为人们所喜爱。苹果有很多品种,每个品种有其固有的特性,并要求一定的环境条件。因此,只有在了解每个品种的习性之后,根据自然条件把它配置在适宜的地区,才能使它们的生产潜力得到充分发挥,这就是品种的区划。本文是多年来调查研究结果的一部分。主要介绍品种区划的意义、研究方法和内容,以及区划的结果。在分析现有栽培品种和砧木适应性的基础上,提出了各区相应的品种,砧木和发展中应注意的事项。(一)品种区划的意义
Apple is the main tree species in fruit trees, widely cultivated, high yield, good quality, resistance to storage and transportation, has long been loved by people. Apple has many varieties, each of which has its own inherent characteristics and requires certain environmental conditions. Therefore, it is only by understanding the habit of each species, according to the natural conditions of its allocation in the appropriate area, in order to make their full potential of production to play, and that is the division of varieties. This article is part of the research findings over the years. Mainly introduces the significance of species division, research methods and content, as well as the results of zoning. On the basis of analyzing the adaptability of existing cultivars and rootstocks, the corresponding varieties, rootstocks and the matters needing attention in the development are put forward. (A) the significance of species division
