| 摘 要： | 在前人理论研究和田间试验的基础上，考虑水分胁迫影响的后效性及作物不同发育阶段对水分胁迫的敏感性，研制出实际水分条件下的冬小麦生长模拟模式。经与不同水分处理的实测资料对比，模拟效果基本令人满意，平均误差为10%左右。利用生长模式得到实际水分条件下的干物重减少率，进行了干旱影响实时评估的尝试。并分别在返青后、拔节后和成熟前展望了干旱对最终生物量的可能影响。

| Abstract: | Based on the previous research and field experimental data, a growth simulation model of winter wheat under actual water conditions was developed in consideration of lag effects of water stress and the different sensitivity of wheat to water stress in various developmental stages. The simulated results are fairly satisfied in comparison with the measured data of different water treatments, the average error is about 10%. The calculated weight reduction of total dry matter caused by water stress was successfully used to assess the influence of drought on growth of winter wheat. The possible effects of drought on final biomass were prospected in the end of return green and jointing stage and prior to maturity stage |
