The current lack of natural water resources, mainly due to the absence of sufficient precipitation and the deterioration of irrigation water (IW) quality, urgently requires a search for alternative resources, especially in arid and semiarid areas. Desalination of sea water is well established in numerous regions where water is scarce. To investigate the effects of the combination of regular fresh water and desalinated sea water (DSW) on mineral nutrient changes in crops, an experimental system based on Musa acuminata AAA plants was performed in Frontera (El Hierro, Canary Islands). Data showed that banana crops irrigated with a mixture of fresh water and DSW exhibited an adequate nutritional status and did not suffer any injuries of salt ions (Na⁺ and Cl⁻) or B toxicity. Moreover, plants may tolerate higher concentrations of these elements and a major supply of the other essential micronutrients. The obtained results suggest that irrigating crops with a combination of fresh water and DSW is a good strategy to respond to the high water requirements, at least under the tested experimental conditions. This strategy could be very helpful in arid regions, as well as in other areas where precipitation is seasonal and scarce, like the Mediterranean or the Canaries.

当前，主要由于降水不足和灌溉水（IW）质量恶化导致天然水资源匮乏，迫切需要寻找替代资源，特别是在干旱和半干旱地区。海水淡化在许多缺水的地区已经很成熟。为了研究常规淡水和淡化海水 (DSW) 的组合对作物矿质养分变化的影响，在弗龙特拉（埃尔耶罗，加那利群岛）进行了基于Musa acuminata AAA 植物的实验系统。数据显示，用淡水和 DSW 混合灌溉的香蕉作物表现出足够的营养状况，并且没有受到盐离子的任何伤害（Na⁺和 Cl ^- ) 或 B 毒性。此外，植物可能耐受更高浓度的这些元素和其他必需微量营养素的主要供应。获得的结果表明，至少在测试的实验条件下，用淡水和 DSW 的组合灌溉作物是应对高水需求的好策略。这种策略在干旱地区以及其他季节性降水稀少的地区（如地中海或加那利群岛）可能非常有用。
