| 摘 要： | 本文通过田间咸水灌溉试验，研究在不同咸水灌溉条件下，运城盆地湖区灌区土壤水盐运移规律及其对农作物产量的影响，进一步探讨表层盐化土壤区咸水灌溉适宜的灌溉制度。研究结果表明：灌区咸水适宜的灌溉定额为８２５－９７５米＾３／公顷，灌区上游矿化度小于３克／升的微咸水适宜的灌水次数为４次；灌区中游矿化度３－５克／升的咸水适宜的灌水次数为２－３次；灌区下游矿化度５－７克／升的咸水灌水次数最多不能超过１次。该研究

| Abstract: | A salt water irrigation test was carried out to study soil salt-water dynamics and its effect on crop yields under conditionsof different salt water irrigation systems and to further study the suitable system of salt water irrigation in the Huqu irrigation area of Yuncheng Basin. The results show that the suitable quota of salt water imigation ranged from 825 to 975m3/ha and the suitable irrigation was 4 times in the area with a mineralization degree changing from 1 to 3g/L, 2~3 times in the area with a mineralization degree ranging from 3 to 5g/L, and 1 time in the area with a mineralization degree ranging from 5 to 7g/L. |
