| 摘 要： | 利用微型蒸渗仪研究了喷灌条件下冬小麦生长期间的土壤棵间蒸发过程，分析了3个不同灌溉量下的棵间蒸发占蒸散的比例及其随叶面积指数和表层土壤含水量的变化关系、灌溉后土壤蒸发的变化过程。通过对试验过程和实测数据的分析，总结了在喷灌条件下土壤棵间蒸发的规律，为制定喷灌的灌溉制度提供理论依据。

| Abstract: | The micro lysimeters were employed to determine the process of soil evaporation of winter wheat at its growth stages under sprinkling irrigation condition. Ratios of soil evaporation to evapotranspiration at each growing stage of winter wheat were investigated in the wheat field with different water treatments. The effects of soil moisture and leaf index on the ratio of soil evaporation to evapotranspiration, and the changes of soil evaporation after irrigation were also analyzed. With the analysis of the experiment process and the observation data, the characteristics of soil evaporation were pointed out accordingly; the results also show some merits in making the sprinkle irrigation norm. |
