北疆地区冬季严寒,发展果树生产,除伊宁,塔城的部分地指区以外,都要匍匐栽培。 奇台农场上山地区现有18年以上直立苹果树两千八百余亩,曾经受了一九六六年冬和一九七六年冬两次周期性的冻害,但仍显示出强大的生命力,苹果产量由一九七二年的十万斤,上升到一九八一年的三百四十万斤。本地区,海拔较高,无霜期短,年平均气温和冬季气温都较低,为什么苹果能够直立栽培越冬呢? 根据苹果树的生物学特性,对奇台农场
Cold winter in northern Xinjiang, the development of fruit production, in addition to Yining, Tacheng part of the area outside, we must prostrate cultivation. There are more than 2800 acres of erect apple trees over 18 years in Qikitai farms in the mountainous area. They were once subjected to two periodic frostbites in the winter of 1966 and the winter of 1976, but still show strong vitality Apple production rose from one hundred jin in 1972 to 3.4 million jin in 1981. The region, high altitude, short frost-free period, the annual average temperature and the winter temperatures are low, why the apple can upright winter cultivation? According to the biological characteristics of apple trees, Qitai farms
