摘　　要：为更科学精准地评估和预测甘蔗蔗糖分,提高蔗糖产量预报的准确率,本文结合无雨日数、降水量、日照时数等气象数据,主要对2007~2021年广西32个甘蔗主产县(市、区)气象站历年9~11月、12月~翌年2月气温日较差对相应榨季广西平均蔗糖分的影响进行分析,研究表明:①甘蔗蔗糖分转化积累关键期(9~11月)气温日较差大利于蔗糖分转化积累;②可基于9~11月气温日较差并结合未来降雨、光照等气象要素开展榨季甘蔗蔗糖分转化积累影响预估和蔗糖分预报。研究结果能为保障我国食糖安全以及糖企生产管理决策提供科学支撑。To evaluate and forecast sucrose content of sugarcane scientifically and accurately,improving the accuracy of sucrose yield forecast,this study analyzed the influence of the daily air temperature range on the average sucrose content in the corresponding press season,combining the data of rainless days,precipitation,sunshine hours from September to November,December to February of the following year of 32 sugarcane producing counties(cities and districts)in Guangxi(2007~2021).Results were as followed:①During the critical period of sucrose conversion and accumulation in sugarcane from September to November,large daily air temperature range was beneficial to sucrose conversion and accumulation.②Based on the mean daily air temperature range from September to November and combined with the meteorological factors such as future rainfall and sunshine duration,the prediction of sucrose conversion and accumulation and the forecast of sucrose content in sugarcane during the press season can be carried out.Results would provide scientific support for ensuring sugar safety and sugar enterprises'production and management decisions in China.
