研究结果表明minhas模型均能较好的表达本地区这两种作物的产量与生育阶段水分之间的量化关系。 |
| 7. | Through 3 - year field experiment , mathematical models were established for yields of spring and winter wheat , soil wetness , designed irrigation depth and fertilization rate . 8
6 .通过三年田间试验，建立了喷灌条件下冬小麦、春小麦产量与土壤湿度、计划湿润层深度和追肥量三因素间的数学模型。 |
| 8. | The sensitivity indices at different growth stages of the two models differ significantly , which indicates that the time of occurrence of water deficit has a great influence on the reduction of the yield of spring wheat an maize
这一结果可能是由于minhas模型的自变量采用b _ 0和_ i双重幂指数的数学结构，而能够较好反映干旱区作物对水分敏感的特性。 |
| 9. | The relationship between crop yield and water use of spring wheat and maize was studied using the data respectively . the results show that crop yields of spring wheat and maize hold an roughly good linear relationship with seasonal evapotranspirations respectively
