| 摘 要： | 根据冬小麦生长发育与土壤水分条件关系的机理研究,建立了田间条件下的土壤水分运动与作物生产耦合机理模型。该模型包括土壤水分运动子模型和作物生长发育子模型,分别模拟了棵间蒸发、根系吸水、生育期、光合、呼吸、同化物分配、根系生长、叶面积增长、产量形成等过程。用1995-10～1996-06的田间试验资料对模型进行验证,结果表明该模型能较好地模拟土壤水分运动与作物生长发育过程的耦合关系。 |

| Abstract: | Based on the coupled mechanism of soil water condition and crop growth and development,a dynamic model is established to simulate the coupled processes of soil water movement and crop growth for the winter wheat.The model contains soil water movement submodel and crop growth and development submodel,and simulates soil evap- oration,root water uptake,photosynthesis,respiration,assimulation partitioning,in- crease of leaf area,root growth and yield formation.The authors use the data of winter wheat in Oct.199... |
| Keywords: | soil water movement crop growth and development simulation coupled mechanism model |
