泉州市郊耕地土壤有效磷含量状况及管理对策

Status of available phosphorus content in cultivated soil of Quanzhou suburbs andits management countermeasures

摘要: 对泉州市郊耕地土壤进行取样分析, 结果表明:土壤有效磷变化幅度为0.7~550.0 mg/kg, 平均值81.4 mg/kg, 水稻土有效磷含量丰富水平的土样数比例达69.2%, 旱地土壤有效磷含量丰富水平的土样数比例达97.0%;泉州市郊耕地土壤有效磷含量总体呈丰富水平;据此提出耕地的磷素管理对策。

Abstract: Soil samples taken from cultivated land in Quanzhou suburbs were analyzed, the results showed that the variation range of available phosphorus was 0.7-550.0 mg/kg with the average 81.4 mg/kg , and the ratio of samples, in which the available phosphorus contents at abundant level in paddy soil and upland soil reached 69.2% and 97.0% respectively, generally, the cultivated soil in Quanzhou suburbs showed abundant level. Based on the analysis, some management countermeasures on phosphorus in cultivated soil were put forward.
