北疆准噶尔盆地南缘,生长季在140—160天以上,适于苹果栽培。惟冬季极端低温可达-39—-41℃,超过苹果耐寒极限。生产上采用匍匐栽培方法,控制苹果树冠在地表上80厘米的低空范围内,便于埋土保护,安全越冬。这个地区便成为新疆著名的果树匍匐栽培区。匍匐栽培的苹果树,在生长发育方面的若干特性,与直立栽培有不同的表现。现就这一地带8—9年生匍匐栽培的苹果进行的观察,简述如下。 一、生长特性方面 1.主干倾角大小与萌芽率及成枝率的关系:以9年生夏立蒙苹果树为材料,测得主干倾角20.4°、46.3°、73.0°,其萌芽率分别为
The northern margin of the Junggar Basin in northern Xinjiang, growing season in more than 140-160 days, suitable for apple cultivation. However, extreme low temperature in winter up to -39 - 41 ℃, more than Apple cold tolerance. The production of prostrate cultivation methods, the control of apple canopy in the surface of the low-altitude range of 80 cm, easy buried protection, safe wintering. This area will become Xinjiang’s famous fruit tree creeping cultivation area. Prostrate cultivation of apple trees, in the growth and development of certain characteristics, and upright cultivation have different manifestations. Observations on 8-9-year-old prostrate apples in this area are summarized below. First, the growth characteristics 1. The main dip angle and the germination rate and the relationship between the rate of branching: 9-year-old summer apple trees as the material, measured the main inclination of 20.4 °, 46.3 °, 73.0 °, the germination rates were
