安徽省主要土壤磷素形态的研究

The Major Types of Soil Phosphorus in Anhui Province

研究了安徽省分布面积较大的６种类型的土壤磷素形态及其含量。结果表明：磷素形态以无机形态为主，耕作层的速效磷高于心土层。

The phosphorus types in six types of soil in Anhui province were studied.The results showed that:the inorganic P is the main type of phosphorus in tested soil,the readily available phosphorus in cultivated horizon is higher than that in subsoil layer.The relationships the readily availbility of phosphorus and Ca2-P,total labile P were closely related.
