摘　　要：　通过对近年来频频发生在新疆北疆地区的桃树冻害情况进行调查分析,结果显示幼树和徒长树的受冻情况比成龄树和树势中庸树严重,但衰弱树也易受冻;花芽冻害重于叶芽,长果枝花芽比中、短果枝花芽易遭受冻害。认为冬季气温偏低,低温持续时间长,或冬春时节忽冷忽热,温度变化幅度大,以及埋土防寒措施不当,是造成桃树冻害的主要原因。提出了一套桃树的综合防寒栽培技术措施。The winterinjury of peaches that happened frequently to northern Xinjiang was investigated and analysed. The result showed that winterinjury happened to young, overgrown, and weak trees more seriously than to vigorous trees. Flower bud was injured by chilliness more easily than leaf bud. And the flower bud of middle and short fruit branches was more resistant to chilliness than that of long fruit branches. The main reason that causes winterinjury of peaches was low temperature and its long duration and fugacious change in early Spring. Unsuitable coverage also causes winterinjury.This paper brings forward a compositive measure of chillproof growing for peaches in dry and chill region.
