| 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(T leaf) 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 T leaf 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 T leaf 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. |
