【摘要】 通过大田试验,测定了地表下5、10、15、20、25 cm处在8∶00、14∶00和18∶00 3个时刻的土壤温度,并对温度特点进行了比较分析.结果表明:波涌灌溉可以调节土壤表层温度,使表层温度保持在一个相对稳定的状态,从而给作物创造了良好的生长环境.另外,对波涌灌溉的节水效果也进行了研究,发现波涌灌溉比连续灌溉可节水10%~20%.更多还原

【Abstract】 By field experiment,the temperature of 5,10,15, 20 and 25 cm depth of soil at 8∶00,14∶00 and 18∶00 was measured,and the characteristics of soil temperature were studied.The results showed that surge flow irrigation could adjust the soil temperature and keep it at a relatively stable state so as to create a better surrounding of the crop growth.The effect of water saving under surge flow irrigation was finally disccussed and the results indicated that surge flow irrigation could save water by 10 %～20 % in comparision with continuous irrigation.更多还原
