| 摘 要： | 以内蒙古浑善达克沙地人工草地种植青贮玉米为研究对象,对两年灌溉试验数据应用FAO-56双作物系数法模拟计算了不同试验处理的青贮玉米实际需水量(蒸散量)。研究了需水量与玉米鲜物质产量、水分利用效率和边际产量之间的关系,并以水分利用效率和边际产量最高为原则确定了干旱地区青贮玉米高效用水灌溉制度。 |
| 关 键 词： | 人工草地 青贮玉米 高效用水 灌溉制度 |

| Abstract: | This study based on the two year's experimental data of millet harvested fresh growing at the grassland planted by person of Inner Mongolia Hunshandake sandy area to simulate millet water requirement(ET) by using dual crop coefficient approach presented in FAO-56.The relationships between millet water requirement and fresh millet yield,between millet water requirement and water utilizable efficiency,and between millet water requirement and marginal product have been analyzed.The high efficient irrigation schedule with different probability rainfall has been determined under the objective of maximizing water utilizable efficiency and marginal product. |
| Keywords: | Grassland planted by person Silage maize High efficient water use Irrigation schedule |
