采用两种阴离子交换树脂提取黄河三角洲滨海湿地碱蓬群落土壤有效磷,通过对比分析,确定了最佳的吸附时间(16 h)和解吸时间(2 h),并对黄河三角洲滨海湿地碱蓬群落土壤树脂磷含量及剖面分布特征进行研究,结果表明:各土层树脂磷含量在11.91～24.56 mg/kg之间,平均值为16.51 mg/kg;极大值和极小值分别出现在0-10 cm和20-30 cm的土层,当土层深度大于30 cm时,树脂磷的含量变化不大。 Two kinds of anion exchange resins were used to extract soil available P from the Suaophylla spp. In the Yellow River Delta. The optimal adsorption time (16 h) and desorption time (2 h) were determined by comparative analysis. The results showed that the content of phosphorus in each soil layer was between 11.91 and 24.56 mg / kg with an average value of 16.51 mg / kg, and the maximum and minimum values ​​appeared in 0- 10 cm and 20-30 cm soil layers. When the soil depth is more than 30 cm, the content of resin P does not change much.
