刘全友 %A 童依平 %A 孙建华 %A 李继云 %J 中国生态农业学报 %D 2003 %I %X Sixty-one topsoil samples around Duolun County were collected and analyzed.The results show that soil organic matter content averages 3.10g/kg (0.89~13.68g/kg),alkaline hydrolytic nitrogen 26.6mg/kg (50.1 ~ 1325.0mg/kg),Olscn-P 4.89mg/kg (1.0-15.0mg/kg),available potassium 126.Omg/kg,available zinc 0.68mg/kg (0.18 ~ 4.18 mg/kg).available manganese 12.9mg/kg (2.44-34.57 mg/kg).water soluble boron 0.49mg/kg (0.12 ~0.94mg/kg),and available molybdenum 0.05mg/kg(0.027 ~ 0.091mg/kg).Evaluations according to the above results indicate that 32.7% of the soil samples are deficient in available N,58.9% in P,19.5% inK,88.7% in Zn,52.7% in boron,24.3 % in Mn.Distribution map of the available soil nutrients are drawn and reclamation measures are recommended also. %K Agriculture and pasture interlaced area %K Soil %K Element %K Reclamation measures
