中文摘要：

田间试验表明,地面畦灌、喷灌和滴灌改变了土壤温度的剖面分布特征。喷灌和滴灌处理表层温度低于地面灌溉处理,而且剖面温差小。高频率的灌溉使得滴灌处理表层土壤温度低,最高温度分布在土壤20cm深度左右,剖面温度分布呈现＂S＂型特征。喷灌处理表层温度也较低,除表层外土壤温度的剖面分布可以近似为指数函数的分布特征。地面畦灌处理土壤温度的剖面分布表现出明显的指数函数分布特征。灌溉方法对土壤温度剖面分布特征的研究有助于分析不同灌溉方法的灌溉效应。

英文摘要：

Field experiment was carried out to research soil temperature profile distribution affected by surface irrigation,sprinkler irrigation,and drip irrigation.Results showed that soil temperature in the surface under sprinkler and drip irrigation were lower than that under surface irrigation,and temperature variance was small.Caused by the high frequency irrigation,the lowest temperature appeared under drip irrigation.The highest temperature was showed at 20 cm depth.Soil temperature distribution showed the ＂S＂ form pattern.Soil temperature under sprinkler irrigation was lower than that under surface irrigation,showed the exponential distribution pattern by the deletion of values in the surface.Temperature distribution showed the exponential distribution pattern under the surface irrigation.Research on soil temperature profile distribution pattern under different irrigation methods was help to analyze the growth of plant caused by irrigation methods.
