咸水灌溉 利用矿化度大于2g/L的咸水灌溉农田使作物得以生长发育的技术措施。在淡水资源短缺的干旱、半干旱地区，为了抗旱增产，许多国家，如突尼斯、意大利、美国、苏联等国，都有咸水灌溉的实践；中东，特别是北非一些国家在具有良好排水和淋洗条件的砂壤土上，用3～8g/L的咸水进行灌溉;有的国家还用稀释的海水灌溉。中国陕西、甘肃、河南、河北、宁夏等省、自治区，也有利用咸水灌溉的经验。 咸水灌溉的主要作用，是增加土壤含水量，稀释土壤溶液浓度，使作物能够生长发育。干旱季节土壤含水量减少，尤其在盐渍化的土地上，随着土壤含水量减少，土壤溶液浓度易于增高，作物吸收困难，根系因失水而死亡。灌咸水后，不仅增加了土壤水分，而且由于咸水的浓度相对较低，降低了土壤溶液浓度，形成了适于作物吸收水分和养分的条件，因而有明显的增产效益。 合理利用咸水灌溉的技术措施主要有：①要有排水条件，以免因灌咸水而引起土壤积盐。可利用雨季降雨或有淡水灌溉时，通过淋洗将盐分排出，使土壤周年不积盐；或在干旱年积盐，平水年及湿润年脱盐。②严格掌握水质标准。一般pH值为7～8，阴离子以硫酸根为主，阳离子中的钠不超过60％，矿化度一般不超过5g/L。③尽量减少灌水次数，宜在作物拔节以后，浇一二次关键水，且灌水定额不宜过大。④有淡水的地方，要咸淡轮灌或咸淡混灌，利用淡水洗盐。⑤加强农业措施，如平整土地，防止灌后局部高地返盐；增施有机肥，培肥地力，抑制返盐；灌后及时中耕锄土，减少土壤蒸发返盐；选种耐盐作物等。⑥若引起长时间连续积盐，应适当休闲，种植牧草，利用伏雨淋洗，或秋冬引淡水冲洗，脱盐后再改种一般作物。 利用浅层地下咸水灌溉，还能降低地下水位，腾出地下调蓄库容，更有利于蓄纳雨水与非灌溉期的地表水，防治渍涝与盐碱灾害，促进地下水淡化。
