摘要
对由向海湿地采集的土壤样品进行了无机磷酸盐形态 (吸附态磷、铝磷、铁磷、闭蓄态磷、钙磷 )分析 ,结果表明 ,钙磷是无机磷酸盐的主要组成部分 ,在各土壤发生层中含量最高 ;除吸附态磷外 ,其它各形态的磷含量总体上有随土壤深度增加而逐渐减少的趋势。铝磷、铁磷、闭蓄态磷受 p H值的影响显著 ,与 p H值呈显著负相关 ,而吸附态磷与钙磷含量则受 p H值的影响甚微。
Different inorganic phosphorus forms (Ads-P,Al-P,Fe-P,Obs-P and Ca-P) of soil taken from Xianghai wetland were analyzed. Ca-P was found to be the major component of the total inorganic phosphorus and found that its content in each soil layer was highest. Except Ads-P, the content of all the other forms of inorganic phosphorus decreased with the depth of soil increasing. The results also show that Al-P,Fe-P and Obs-P were influenced significantly by pH, and pH and them had significant negative correlation, however, Ads-P and Ca-P were not almost affected by pH.
