〔概况〕苹果的矮化栽培因能获得结果早,丰产、品质好,便于管理等显著成绩,而成为世界各国果树生产发展的新动向,树体矮化的方法是多种多样的,矮化砧木是其中的一种,它有效果好,管理容易等优点,但因为它存在矮化砧本苗繁殖率低,手续繁琐,抗寒、抗旱力差,容易倒伏等缺点,限制了它在生产上的推广.尤其在北疆地区直立栽培果园,无法解决矮化砧本的越冬问题.为了找到一种适应性强,能在北疆地区露地越冬的抗寒矮化砧木,我们根据《植物学杂志》一九七四年一卷一期刊登张文善(北京市园林局绿化处)同志的一
[Overview] The dwarfing cultivation of apples has made remarkable achievements such as early yield, high yield, good quality and easy management and has become a new trend of fruit tree production and development in various countries in the world. The method of dwarfing trees is diversified and dwarfed Rootstocks are one of them, which is effective, easy to manage and so on. However, its shortcomings such as low reproduction rate, cumbersome procedures, cold hardiness, poor drought resistance and easy lodging are limited by its short production, Especially in the north of Xinjiang cultivation of orchards, dwarfing anvil can not solve the problem of overwintering.In order to find a strong adaptability, can be exposed in the northern territory of winter cold dwarfing rootstock, according to “botany Magazine ”one volume one in 1974 published Zhang Wenshan (Beijing Gardens Bureau Green Branch) comrades one
