盐度是世界上主要的环境胁迫。大约30%的耕作土壤遭受盐分胁迫.盐胁迫影响植物生长、发育和作物生产力，特别是在干旱和半干旱地区。一些文章报道了盐与营养之间的关系，即营养失衡、营养缺乏、营养代谢受盐积累的影响。盐胁迫导致Na+和Cl−离子在植物细胞中的极端积累。在矿质营养元素中，氮和磷是植物营养生长和生殖生长阶段最重要的营养元素。本章重点介绍了盐胁迫对植物氮磷吸收、利用、代谢和体内平衡的影响。
Salinity is the major environmental stresses in the world. Approximately, 30 % of cultivated soils are suffered from salinity stresses. Salinity stresses affect plant growth, development, and crop productivity, particularly in arid and semi-arid areas. Several articles report that relationship between salinity and nutrition, i.e. nutrient imbalances, nutrient deficiencies, nutrient metabolism are influenced by accumulation of salt. Salinity stresses causes extreme accumulation of Na+and Cl−ions in plant cells. Among mineral nutrients, nitrogen and phosphorus are most important nutrients for plants in both vegetative and reproductive stages. In this chapter, the effect of salinity stress on N and P uptake, utilization, metabolism, and homeostasis in plants is focused.
