| 摘 要： | 试验研究分蘖期、拔节期和开花期复水对受旱冬小麦的补偿效应结果表明，各生育期复水对冬小麦的生长和产量均有不同程度的促进作用，复水处理的冬小麦株高、绿叶面积、干物质量及产量等均超过其干旱对照，表现出补偿生长效应，其中拔节期复水的补偿作用最大，增产效果最明显，开花期复水次之，分蘖期复水最小。苗期干旱拔节期复水可达到节水和提高产量的目的。

| Abstract: | The compensatory effects of supplying water after drought during tillering stage,jointing stage and flowering stage on the growth and grain yield are studied. The results show that rewatering after drought during these growth duration has various degrees of promotion effect on growth and yield respectively. The height of plant,green leaves areas per plant,dry matter weight and grain yield of the rewatered treatments exceed those of their drought controls and show compensatory effects. Rewatering during jointing stage has the most compensatory effects on yield increase,secondy is the rewatering during flowe ring stage,and rewatering during tillering stage is the least.Water-recovery during jointing stage could come to the goal of water-saving and yield increase. |
