| 摘 要： | 棵间土壤蒸发是控制性交替灌溉条件下农田土壤耗水的重要组成部分,为了了解沈阳地区潮棕壤土条件下大豆田不同控制性交替灌溉制度下的土壤蒸发变化规律,对土壤蒸发进行预报,采用Micro-lysimeters(MLS)对不同灌溉处理下的土壤蒸发量进行了测定,并建立了以气象因子、土壤含水率和叶面积指数为自变量的土壤蒸发的预报模型.结果表明,在本试验的条件下,各处理的相对土壤蒸发率(E/ET0)与表层土壤含水率(θ)的关系均呈指数函数形式,决定系数在0.71以上.各处理的E/ET0与LAI之间亦呈很好的指数函数关系,决定系数均在0.78以上. |
| 关 键 词： | 控制性交替灌溉 土壤蒸发规律 相对蒸发强度 |

| Abstract: | Soil evaporation is an important component of water consumption in farmland under controlled alternative irrigation technology.To study the change rule of soil evaporation in maize field under different controlled alternative irrigation scheduling in Shengyang region and predict the soil evaporation,the soil evaporation under different irrigation treatments was measured with micro-lysimeters,and the predict model,which took weather factor,soil water content and leaf area index (LAI) as free variables,was se... |
| Keywords: | controlled alternative irrigation technology the change rule of soil evaporation the relative soil evaporation rate |
