A numerical model (HYDRUS-1D) was used to evaluate the impacts of the long-term (2004–2015) use of sustained deficit irrigation (10% (D10%) and 20% (D20%) less than full), irrigations with increased water salinity (EC_iw of 0.5 and 0.8 dS/m), 50% deficit irrigation during a drought period (DD50%), and DD50% coupled with an increased salinity of water (EC_iw of 0.5 and 0.8 dS/m) on the water balance and salinity dynamics under grapevine in two soils at two locations with different climatic conditions. The results showed that D20% and DD50% significantly reduced water uptake and seasonal drainage (D_r) by the vines as compared to full irrigation. Vineyards established in light-textured soils showed two to five times larger drainage losses as compared to heavy-textured soils. The results revealed that the slight increase in the electrical conductivity of irrigation water (EC_iw = 0.5 and 0.8 dS/m) increased the risks in terms of the amount of salts deposited in the soil and transport of large quantities of irrigation-induced salts beyond the root zone. Hence, it is imperative to monitor all of the important water, soil, and salinity drivers of agro-hydro-geological systems to understand the hydro-salinity dynamics and to ensure the long-term sustainability of irrigated viticulture.

使用数值模型（HYDRUS-1D）来评估长期（2004-2015）持续亏缺灌溉（比完全灌溉少10％（D10％）和20％（D20％））灌溉的影响。水盐分增加（EC _iw为0.5和0.8 dS / m），干旱期间50％的亏水灌溉（DD50％）和DD50％以及水盐分增加（EC _iw为0.5和0.8 dS / m）。不同气候条件的两个地点的两种土壤中葡萄藤下的水分平衡和盐分动态。结果表明，D20％和DD50％显着减少了水分吸收和季节性排水（D _r与完全灌溉相比）。与质地较重的土壤相比，在质地较轻的土壤中建立的葡萄园的排水损失要大2至5倍。结果表明，灌溉水的电导率略有增加（EC _iw分别为0.5和0.8 dS / m）增加了土壤中盐分的沉积以及大量灌溉引起的盐分运输到土壤中的风险。根区域。因此，必须监测农业水文地质系统的所有重要水，土壤和盐分驱动力，以了解水盐分动态并确保灌溉葡萄栽培的长期可持续性。
