Quality and quantity of different irrigation water types from conventional and alternative sources have a significant role on the productive parameters and chemical composition of crop plants. Appropriate alternative water sources and the reutilization of agricultural effluents can reduce the impact of rice production and animal husbandry on the natural water bodies. In the present study, influence of four different types of irrigation water was analyzed on the nutrient uptake (P, K, Ca, Mg, Na) of aerobic rice (Oryza sativa L.) in a complex lysimeter experiment in two consecutive years. Early maturing Hungarian rice varieties (M 488 and Janka) were irrigated with traditional river water (RW) and different alternative irrigation sources to evaluate the feasibility of a sodium containing intensive fish farm effluent with (EWG) or without (EW) gypsum supplementation and with the addition of natural river water (EWGR). Significant effects on the mineral content of the aboveground biomass were measured. P uptake by M 488 and Janka decreased after the irrigation with EW in 2017. In case of EW, EWG and EWGR, the Na content increased significantly (p ≤ 0.05) in both varieties; however, pre-treatment of salt containing effluent waters can moderate the stress level. As a consequence, the ability of both rice varieties to absorb Na suggests that rice production could be conditionally part of bioremediation of salt-affected soils and water bodies.

污水灌溉在好氧水稻品种（Oryza sativa L.）矿物质吸收中的作用

来自传统和替代来源的不同灌溉水类型的质量和数量对作物的生产参数和化学成分具有重要作用。适当的替代水源和农业废水的再利用可以减少水稻生产和畜牧业对天然水体的影响。在本研究中，连续两年在复杂的蒸渗仪实验中分析了四种不同类型的灌溉水对好氧水稻（Oryza sativa L.）养分吸收（P、K、Ca、Mg、Na）的影响。使用传统河水 (RW) 和不同的替代灌溉源灌溉早熟的匈牙利水稻品种（M 488 和 Janka），以评估添加（EWG）或不添加（EW）石膏的含钠集约化养鱼场污水的可行性。添加天然河水（EWGR）。测量了对地上生物量矿物质含量的显着影响。2017年EW灌溉后M 488和Janka对磷的吸收减少。在EW，EWG和EWGR情况下，两个品种的Na含量显着增加（p≤0.05）；然而，含盐废水的预处理可以缓和压力水平。作为结果，
