我国北部,年均温8℃以北的广大地区,包括东北三省的大部,内蒙古、河北坝上,新疆北部,青海、甘肃和西藏等高寒地区称为我国寒地。50年代以前,这里果树生产很落后。特别是苹果,虽然资源较丰富,但果小,酸涩味重,不耐贮藏。栽培品质优良的苹果品种,不能取得较好的经济效益。50年代开始,我国寒地各省(区)相继开展了苹果资源的收集、保存与研究、利用工作,并取得了成功。被应用于生产的品种越来越多,果实逐渐变大,品质也逐渐好起来。到80年代,基本形成了我国特有的抗寒苹果品种群。
In the northern part of our country, the vast area with an annual average temperature of 8 ℃, including most of the three northeastern provinces, Inner Mongolia, Hebei Bashang, northern Xinjiang, Qinghai, Gansu and Tibet is called China’s cold area. Before the 1950s, the production of fruit trees was lagging behind here. Especially apples, although rich in resources, but fruit small, sour taste, impatient storage. Cultivation of good quality apple varieties, can not get better economic benefits. Since the 1950s, various provinces (districts) in the cold regions of China have successively carried out the collection, preservation and research, utilization of the apple resources and achieved success. More and more varieties are used in the production, the fruit is getting larger and the quality is getting better. By the 1980s, the basic cold-resistant apple species population in our country was basically formed.
