摘要:
利用广西90个地面气象观测站2018年1月26~31日日最低气温资料，采用积寒分析法，统计分析了该次低温雨雪冰（霜）冻天气过程中各站日最低气温≤ 4℃的积寒（℃），并应用甘蔗寒冻害等级评估指标及蔗糖分灾损评估指标进行低温寒冻害对产量和糖分影响的定量化评估。结果表明，广西中南部大部蔗区的糖料蔗未产生冻害；但广西北部、中部的部分蔗区出现了轻度寒冻害，轻度寒冻害造成的糖料蔗产量损失低于5.0%、糖分损失在0.2%~0.5%之间；广西北部的蔗区冻害达到中度以上等级，产量损失高于5.0%，糖分损失约0.6%~1.5%。经对评估结果和灾情实况进行对比分析，评估结果与灾情实况基本一致。
Abstract:
Based on the minimum temperature data of 90 surface meteorological observatories in Guangxi from January 26 to 31, 2018, using the method of accumulated cold analysis, the daily minimum temperature of each station lower than or equal to 4℃ during this low-temperature rain, snow and ice (frost) freezing weather process was analyzed. The effects of low-temperature freezing injury on yield and sugar content were quantified by using the evaluation indexes of sugarcane freezing injury grade and sucrose damage. The results showed that sugar cane did not suffer frost damage in most sugarcane areas in south-central Guangxi; however, some sugarcane areas in North and central Guangxi suffered from slight frost injury. It was predicted that the loss of sugarcane yield caused by slight frost injury was less than 5.0% and the loss of sugar was between 0.2% and 0.5%. The frost injury in Northern Guangxi may reach the level above moderate, and the estimated loss of sugarcane yield was higher than 5.0%, and the loss of sugar was about 0.6%. to 1.5%. By comparing and analyzing the evaluation results and the disaster situation, the evaluation results are basically consistent with the disaster situation.
