摘要
研究不同灌水技术下土壤温度的变化,通过设置不同灌溉制度的处理监测不同土层深度的土壤温度的连日变化. 试验结果表明：不同水分处理总体上对5 ~25 cm土壤温度影响明显,各水分处理对5 个深度测得的土壤温度平均值以对照处理最高,微润灌处理最低,滴灌处理居中. 说明各个水分处理都能在不同程度上起到增加土壤温度的作用. 各水分处理中滴灌处理在各生育期内各土层平均土壤温度最大,微润灌处理在各生育期内各土层平均土壤温度最小,对照处理居中,在各生育期平均土壤温度有所差异,分析表明滴灌处理的增温效果最好.
Under different irrigation technology in order to study the change of soil temperature, the paper is based on set-ting the different irrigation system and monitoring the processing of a series of different soil depth of soil temperature changes. The test results show that different water treatment on the overall 5 ~25 cm soil temperature affects significantly, different wa-ter temperature on the depth of five highest measured the average soil temperature to control processing, micro irrigation treat-ment minimum, drip irrigation temperature center. How each water treatment can have the effect of increasing soil temperature in different degree. Various water treatment of drip irrigation in each period of fertility soil average maximum temperature, soil, tiny embellish irrigation treatment at all stages of the soil average soil temperature minimum, control processing center, in various stages of the average soil temperature differences, analysis showed that drip irrigation treatment effect of warming is best.
