摘要: 低温冻害是制约喀什石榴产业发展的主要灾害之一,通过对喀什市国家基准气候站1981—2022年冬季的气象资料分析以及历史冻害发生年份调查,研究石榴越冬期不同气象要素的变化特征,结合历年冻害发生年份气象要素的变化,阐明石榴越冬期冻害发生与气象因子的关系,确定石榴越冬期造成冻害的气象指标。结果表明:越冬期极端日最低气温、低温持续日数、最低气温的降温幅度和冬季积雪深度为影响喀什石榴安全越冬的冻害气象指标。研究以期为喀什石榴安全越冬防寒技术措施提供科学理论依据。

Abstract:

Overwintering freezing injury caused by Low temperature is one of the main disasters that restrict the development of forests and fruits. In this paper, through the analysis of the winter meteorological data from 1981 to 2022 years of Kashi National Climate Reference Station and the historical record of freezing disaster investigation, the variation characteristics of different meteorological elements in the overwintering period of pomegranate were studied. Combined with the changes of meteorological elements of freezing injury over the years, the relationship between the occurrence of freezing injury in the overwintering period of pomegranate and meteorological factors was clarified, and the meteorological indexes causing freezing injury in the overwintering period of pomegranate were determined. The results showed that, based on the extreme minimum temperature, duration of low temperature for several days, the drop degree of extreme minimum temperature and the snow depth in winter was the meteorological indicators affecting the safe overwintering of pomegranate in Kashi. This study provides a scientific theoretical basis for the technical measures of safe overwintering and cold prevention of pomegranate in Kashi.
