所谓咸水,指高矿化度水,目前国际上普遍采用的盐分划分等级为:淡水——矿化度为1克/升,轻度盐化水——矿化度为1-3克/升,中度盐化水——矿化度为3-10克/升,盐化水——矿化度为10-35克/升.海水的盐分为35克/升. 国外关于咸水灌溉的研究表明,利用盐水灌溉未产生盐渍化土壤的作用.对沙土可供灌溉的水的含盐量可达5克/升,对重壤土灌溉水的含盐量为2-2.5克/升.在有良 The so-called salt water, refers to the high salinity of water, the current international salt classification level commonly used: freshwater - salinity of 1 g / l, slightly salinized water - salinity of 1-3 g / L, moderate salinization of water - salinity of 3-10 g / L, salinized water - salinity of 10-35 g / L. Saltwater salt is 35 g / L. Studies have shown that the use of salt water irrigation did not produce salinized soil effect on the soil available for irrigation water salinity up to 5 g / L, heavy loam irrigation water salinity of 2-2.5 g / L There is good
