摘要
两年的盆栽试验表明,小麦孕穗期对水分胁迫最为敏感,其次为开花期.干旱主要是通过减少籽粒数来影响产量的.用红外测温仪测定干旱麦田和湿润麦田的叶丛温差,是诊断小麦干旱之简便而有效的方法.
Water stress treatments at different development stages of a winter wheat variety were made by outdoor pot experiments from 1987 to 1988.It was found that the most sensitive stage was the booting stage and the second most sensitive stage was the flowering stage. Water stress at most development stages affects the number of grains. Wheat water stress can be determined effectively and quickly by means of leaf temperature measured by an infrared thermometer in the drought field and the well watered reference plot.
