Abstract: A field experiment was carried out using method of artificial flooding simulation,and the effects of waterlogging stress on osmotic regulation ability,yield and quality of peanut were discussed under flat planting and ridge planting condition. The results showed that,waterlogging stress had significant effect on peanut growth,the contents of chlorophyll and soluble protein were significantly decreased,and the content of proline was increased obviously. Compared with flat planting,ridge planting reduced the adverse effects on peanut plant,and maintained higher soluble sugar content and soluble protein content,which were conducive to the maintenance of leaf physiological characteristics.The peanut yield was decreased by waterlogging stress. Under waterlogging stress in pod setting stage,the yield increased by 20. 42 % under ridge planting condition compared with flat planting condition,while the value was 13. 22% in maturation stage. Waterlogging stress can affect the yield and quality of peanut obviously,which was more serious in pod setting stage. In addition,compared with flat planting,increased the content of oleic acid and fat,and improved the quality of peanut.
