摘要
[目的]研究聊城市210个园地土壤样品有效磷状况.[方法]采集具有代表性的园地土壤样品210个,采用LY/T 1232-2015碳酸氢钠浸提法测定土壤样品中的有效磷含量.[结果]聊城市土壤有效磷平均含量为46.0 mg/kg,变幅为19.4 ~88.4 mg/kg.[结论]根据土壤肥力分级指标园地指标划分,等级为 Ⅰ 级的土壤有效磷含量占100%,处于极丰富水平.

[Objective] To study available phosphorus situation of 210 orchard soil samples in Liaocheng City.[Method] 210 representative soil samples were collected,and the effective phosphorus content of soil samples was determined by using sodium bicarbonate extraction of LY/T 1232-2015.[Result] The average content of available phosphorus in soil of Liaocheng City was 46.0 mg/kg with the range of 19.4-88.4 mg/kg.[Conclusion] According to the soil fertility classification indexes of orchard soil index, the effective phosphorus content in soil with the grade Ⅰ account for 100 %, which is extremely rich level.
