The Regional Breeding Structure Affect for Soil Phosphorus Balance of Farmland System--A Case of Xiangtan County

摘要：

　　For expioring the regional planting and breeding structures influence on soil phosphorus balance of farmland system, this paper analysed the breeding structure of Xiangtan County regional farmland system based on the statistical data of Hunan province.The result shows that soil phosphorus balance of Xiangtan County regional farmland system mainly depends on phosphorus inputting of fertilizers and manure as well as the phosphorus output caused by production of farm crops.The average of soil phosphorus surplus about arable and cultivated area presented a more clear upward trend.And counting from 2000 to 2011, it were 25.59 kgP· hm-2 and 13.49 kgP · hm-2.The reason can be attributed to a large number of input of fertilizer containing phosphorus within regional farmland system.
