近几十年来,国外一些国家,在苹果栽培方面逐渐由乔砧稀植(每亩栽10—15株)改为矮化密植(每亩栽50—110株)达到了管理方便,结果早、产量高、品质好、收益快的目的。用矮化砧木代替乔化砧木已成为当前世界上苹果栽培的发展趋势,也是现代化、集约化果园的重要标志之一。我国河南、山西、山东等省,引入国外矮化砧木进行试验,取得显著成效,有的果园已进入推广和扩大栽培阶段。我省此项研究自1973年开始,引入英国的M、MM系矮化砧木的近二十个砧号进行繁殖。重点砧号M_2、M_4、M_7,M_9等在一些地、州、市(县)通过栽培试验,几年来生长、结果表现与国内外一致。为使这项新技术在我省得到推广应用, In recent decades, in some foreign countries, the planting of apple trees has gradually been replaced by the planting of small plants (10-15 plants per mu) to the dwarfing dense plants (50-110 plants per acre) in apple cultivation. As a result, High yield, good quality, quick income purposes. The replacement of Qiaohua rootstock with dwarfing rootstock has become the trend of apple cultivation in the world at present and is also one of the most important symbols of modernization and intensification of orchards. China’s Henan, Shanxi, Shandong and other provinces, the introduction of foreign dwarfing rootstocks for testing, and achieved remarkable results, and some orchards have entered the promotion and expansion of cultivation stage. This study in our province since 1973, the introduction of the British M, MM Department of dwarfing rootstock nearly twenty anvil numbers for breeding. Key anvil M_2, M_4, M_7, M_9 and so on in some places, state, city (county) through cultivation tests, the growth of a few years, the results of performance consistent with the domestic and foreign. In order to make this new technology popularized and applied in our province,
