| 摘 要： | 在冬小麦不同种植方式下,研究了麦田的逐日蒸发过程,对比分析了麦田蒸发占蒸散的比例及其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。结果表明:与单作相比,间作麦田土壤蒸发量增加了34.63mm,作物蒸腾量减小了65.81mm,ET值减小了31.18mm;单作麦田E/ET为20.42%,间作麦田E/ET为29.72%。

| Abstract: | On the bases of different planting ways, diurnal changes of soil evaporation from wheat field were investigated. Ratios of soil evaporation to evapotranspiration in each growing stages of winter wheat were analyzed. The effects of soil moisture on the ratio of soil evaporation to evapotranspiration, and the change of soil evaporation after irrigation were also analyzed. The results showed that compared with the monoculture, the evaporation of intercropping increased 34.63 mm, transpiration decreased 65.81 mm, evapotranspiration decreased 31.18 mm.The ratio of E/ET of the monoculture was 20.42%,the intercropping was 29.72%. |
