In order to keep the soil and water function of farming measure “Ridge Plotted Field” in areas with heavy rainfall,the paper selected three farming measures such as namely cross slop tillage, ridge plotted field and ridge hayrick field as test treatments in comparison with the traditional measure of down slop cultivation so as to study the planting effect of ridge hayrick field in the low hilly land of Youziling of Hengnan county of Hunan province.The results showed that under condition of the same rainfall,the order of runoff, erosion and nutrient loss at every region from big to small is down slope cultivation(CK),cross slope tillage(CT),ridge plotted field(RA),ridge hayrick field(RF), but the order of crop yield is on the contrary,its sequence from big to small is PF,RA,CT and CK.The time of the maximum runoff and sediment yield is 10 minutes and 5 minutes respectively after rainstorm which is different from the result of previous researches of 10 minutes after rainstorm.The result showed that the ridge hayrick field is an effecive measure for red soil sloping farmland to prevent soil erosion and improve soil fertility,and has a borad application prospect and should be actively popularized and applied.
