土壤盐碱化正在成为农业生产的主要制约因素，严重威胁全球生态系统和粮食安全。据估计，到2050年，由于降水量少、地表蒸发量高、耕作方法差、化肥施用过量等因素，50%的农业用地将盐碱化[1]。值得注意的是，大约60%的盐渍土同时存在碱化问题，这是由大量的碳酸钠（Na 2CO 3）或碳酸氢钠（NaHCO 3）造成的。与纯中性盐胁迫相比，复合盐碱胁迫总是导致更高的细胞氧化应激，更严重的营养离子失衡，渗透调节能力降低，必需营养素的吸收率降低[2]。根据土壤含盐量和pH值，盐碱胁迫可分为轻度（含盐量≤ 0.3%，pH 7.1-8.5）、中度（含盐量0.3%-0.6%，pH 8.5-9.5）和重度（含盐量≥ 0.6%，pH 9.5）胁迫三个等级[3]。随着耐盐碱作物育种工作的不断深入，轻、中度盐碱地有望开发利用。
Soil saline-alkalization is becoming a major constraint for agricultural production, seriously threatening global ecosystems and food security. An estimated 50% of total agricultural land will be salinized by 2050 due to factors such as low precipitation, high surface evaporation, poor cultural practices, over application of chemical fertilizers and so on [1]. It is important to note that approximately 60% of the saline soil has concurrent alkalization problems, conferred by high amounts of sodium carbonate (Na2CO3) or sodium bicarbonate (NaHCO3). Compared with pure neutral salt stress, combined saline-alkaline stress always results in higher cellular oxidative stress, more serious trophic ion imbalance, reduced osmotic adjustment capacity, and reduced uptake rates of essential nutrients [2]. According to the salt concentration and pH value of the soil, saline-alkaline stress can be classified into three levels: mild (salt content≤ 0.3%, pH 7.1–8.5), moderate (salt content 0.3%–0.6%, pH 8.5–9.5), and severe (salt content≥ 0.6%, pH 9.5) stresses [3]. With the progress of salinealkaline tolerant crop breeding, the mild and moderate saline-alkaline soils are expected to be developed for crop production.
