| 摘要: |
| 依据冬小麦根系伸展深度、重量根密度以及土壤含水量分布的实测资料,对冬小麦根系吸水分布进行了动态模拟。在分析根系吸水规律的基础上考虑根系分布状况、土壤含水率、蒸腾速率等因素的影响,建立了一个冬小麦根系吸水模式,该模式经实际应用,效果良好。 |

| Abstract: |
| Based on the measured data of stretching depth, weight density of winter wheat root system as well as the distribution of soil water contents in the profile, a dynamic simulation for water uptake by winter wheat root system was conducted. A model of water uptake by wheat root system was established by taking into account the effects of such factors as root system distribution, soil moisture content and transpiration rate, etc. in accordance with the analysis of water uptake laws by wheat root system. The results of the model are much better in practical application. |
