苹果露地越冬问题是北疆地区大量发展苹果的关键问题。能够露地越冬便可节省大量人工,降低生产成本,同时苹果的生长和发育良好。 过去我们认为,解决苹果在北疆的越冬问题,必须通过育种的道路,因而不可能在较短的时间内得到解决。但是,根据两年来的观察证明,这种看法是不全面的。因为伊犁苹果和塔城的果树品种本身即具有比内地品种较强的抗寒性,同时与本埸气候条件相近,所不同者, The problem of overwintering apples in the open field is a key issue for the large-scale development of apples in northern Xinjiang. To be able to open the winter to save a lot of man-made, reducing production costs, while the growth and development of apples is good. In the past, we believed that to solve the problem of apple overwintering in northern Xinjiang, we must pass the road of breeding and therefore could not be solved within a relatively short period of time. However, based on two years of observation, this view is not comprehensive. Because Ili apple and Tacheng fruit tree species itself has a stronger than the mainland cold hardiness, at the same time and Benxi climatic conditions are similar, different,
