| 摘 要： | 通过棉花膜下滴灌大田试验,研究了灌水频率对土壤水盐运移和分布规律的影响,并对不同灌水频率的保墒、控盐、增产效果进行了评价.试验结果表明:在灌溉水质为淡水且定额为375 mm时,低频(10 d)和适频(7 d)灌溉下膜内0～60 cm土层的含水量适宜,低频灌溉的含水量最高,而高频(3 d)灌溉下各土层在花铃期处于轻度干旱...

| Abstract: | A cotton field experiment under mulched drip irrigation was carried out in order to study the effects of different irrigation frequency on soil water-salt transport and distribution,and to evaluate different irrigation frequencies' efficiency in preserving moisture,controlling soil salinization,and increasing cotton yield.The results show that the soil moisture contents are not the same under different irrigation frequencies with fresh water at 375 mm,namely,low-frequent irrigation(10 days) and middle-frequ... |
