摘要
以畦漫灌为对照,对隔行喷灌、隔行沟灌、膜上灌溉和穴灌4种灌溉方式下玉米的产量及水分利用率进行了分析。结果表明:膜上灌溉产量高于畦漫灌,隔行沟灌、隔行喷灌与畦漫灌接近;膜上灌溉与畦漫灌和穴灌差异达0.01显著水平,与隔行沟灌、隔行喷灌差异达0.05显著水平。灌溉处理的水分利用效率均高于对照的畦漫灌,膜上灌溉的水分利用效率最高。
The experiment analyses the yield and water use efficiency of maize in different ways of localized irrigations, including the septa-irrigation, septa-spurt-irrigation, film above irrigation and cave irrigation, and the flood irrigation as control. The result had showed： the yield of the film above irrigation was better than the flood mode＇s, and the septa-irrigation＇s and septa-spurt-irrigation＇s were close to flood irrigation＇s. The yield of the film above irrigation was significant different from flood irrigation＇s and cave irrigation at 0.01 level, and was different from the septa-irrigation＇s and septa-spurt-irrigation＇s at 0.05 level. The water use efficiency by all the localized irrigation treatments was higher than the flood irrigation, and the film above irrigation＇s was highest.
