| 摘 要： | 在小麦的主要生育期进行了不同土壤湿度和不同持续时间的水分胁迫,研究了土壤湿度对小麦产量及产量形成的影响。结果表明:小麦经济产量、叶面积和单株干重与土壤湿度之间存在极显著的二次函数关系;小麦对水分胁迫最敏感的生育期为拔节-开花期;而且不同生育期的适宜土壤湿度范围不同,并据此确定出南京地区小麦不同生育期适宜的土壤湿度范围。其结果对定量评估不同生育期土壤水分胁迫对产量的影响程度和小麦生产中合理控制土壤湿度范围有一定参考价值。

| Abstract: | The responses of wheat growth and yield to the different soil moistures at different growing stages were investigat-ed.The results showed that the leaf index,biomass per plant and yield of wheat were significantly influenced by soil moisture.The most sensitive stage to soil moisture stress was from elongation to flowering stage.The suitable soil moisture for the different growing stages of wheat was different.The results had provided the valuable reference for evaluating the impact of different soil moisture at different stages on wheat yield and for improving the soil moisture management. |
