摘要
高温热害是水稻生长过程中的主要农业气象灾害之一。本文通过对安徽省桐城市一季稻抽穗开花期叶片温度的大田观测分析,找出了影响晴天水稻叶片温度的因子,建立了叶-气温差的预测模型,可为水稻高温热害诊断分析提供参考依据。
High temperature stress is one of the major disasters in the process of rice growth.By observing and analyzing leaf temperature of single-season rice on ear sprouting to flowering period in Tongcheng Anhui province,factors of impacts on leaf temperature of single-season rice in clear day was found out.Prediction model of leaf-air temperature difference was established.The results could provide a reference to diagnostic analysis the high temperature etress to rice.
