摘要：

为了研究水稻叶片温度与产量关系，以双季早晚稻12个品种为材料，2008—2009年应用红外测温仪记录叶片温度，并分析大气温度、气叶温差与产量的关系。结果表明，水稻叶片温度的日变化呈单峰曲线，变化幅度小于气温；在不同生育阶段品种间气叶温差存在明显差异。各生育时期14:00点的气叶温差与产量呈正相关关系，抽穗期的相关程度最高；抽穗期和抽穗后的剑叶日平均温度与产量呈负相关，剑叶的日平均气叶温差与产量呈正相关；超级稻的气叶温差高于非超级稻。

Abstract:

To study the relation between the temperature of leaf (Tleaf) and yield, 12 variaties of double-cropping rice were measured for leaves temperature and yield by infrared radiation thermometer. These results showed that, the daily vatiation of Tleaf was a single peak curve, the variation range was less than the air temperature. The temperature differences between of air and leaves (TD) were appeared among different varieties in different growth stages. TD had a positive correlation with yield at 14:00 in different growth stages, the highest degree of correlation in heading. The daily average of Tleaf of flag leave had a negative correlation with yield in heading and 15 days after heading (early season rice) or 20 days (late season rice), the average of TD of flag leave had a positive correlation with yield.
