The ionic stress,osmotic stress,oxidative stress and high pH stress of rice grown in saline-alkali soil have adverse effects on rice growth and physiological characteristics.In this paper,the response mechanism of rice to saline-alkali stress was reviewed from the aspects of growth and development,yield and quality formation,nutrient absorption,protective enzymes and expression of stress-resistant genes.The methods of making efficient use of saline-alkali soil by rice planting were proposed such as culture of salt-tolerant Variety and agronomic measures to reduce salt-alkali stress and regulat...
