图4 4个站点不同灌溉水平下冬小麦粒数A, B与粒重C, D的相对变化率 TJ和TF分别表示拔节期至抽穗期和灌浆期干旱, 1~3分别表示轻度、中度和重度胁迫。
Fig. 4 Relative change rates of grain number A, B and grain weight C, D under different irrigation levels in four sites TJ and TF indicate drought stress at jointing-heading and grain filling stages with light 1, moderate 2, and heavy 3 stresses, respectively.
