| 中文摘要: |
| 利用一维垂直非饱和土壤水运动计算模型，通过模拟计算夏玉米生育期各生长阶段不同水文年、不同灌水定额下田间水分转化规律，对棵间蒸发，深层渗漏与灌水定额之间的数量关系进行了定量研究，并建议华北地区夏玉米节水灌溉定额为40m^2/亩。 |
| 英文摘要: |
| In this paper, field soil water balances in root zone is simulated by using one-dimensional variable saturated water flow model under the condition of different hydrographic year and irrigation requirement for summer corn during different growing stage. The relation among the evaporation from cropped soil surface, the leak at bottom and the irrigation requirement have been studied quantitatively. The optimal irrigation requirement recommended by the authors is 600m^3/ha for summer corn in north China plain. |
