影响粤西甘蔗糖分的主要气象因子和糖分预测

通过对粤西甘蔗糖分与气象条件进行相关分析、趋势分析和阶段分析，得出影响粤西甘蔗糖分的主要气象因子是１０、１１ 月的平均最低气温和１１、１２ 月的雨日，用多重回归建立糖分预测经验方程，历史拟合及预测效果好。针对不利的气象条件提出了生产对策。

The major meteorological factors affecting sugar content of West Guangdong Province and forecasting of suger content

In this paper, the sugar content and the meteorological conditions of West Guangdong Province were studied with correlation, trend and phase analysis. The results showed that the major meteorological factors affecting sugar content were average minimum atmospheric temperature in October and November and raining days in November and December. Using multiple regression, three experimental forecasting equations were built. The effect of history imitate and forecasting was good. The measure under unfavourable meteorological conditions was suggested.ward.
