对不同咖啡园土壤磷素形态进行分析研究,结果表明:土壤磷素以无机磷为主,无机磷中以O-P居多,约占无机磷总量的54.63％；有机磷中以中活性有机磷居多,约占有机磷总量的70.14％；随种植年限增加,土壤全磷含量差异显著,但变化趋势不明显,有效磷、Al-P和Fe-P含量呈显著上升趋势,有机磷总量、中活性有机磷、中稳性有机磷、高稳性有机磷呈显著下降趋势；Ca-P、Fe-P、Al-P与有效磷呈显著或极显著正相关.磷素大量积累时主要以增加无机磷组分中有效性较高的Ca-P、Al-P和Fe-P为主.%The forms of phosphorus in coffee garden soils were studied. The results showed that the content of inorganic P was higher than organic P , 0-P was the main form in the inorganic P, accounting for 54.63% of the total inorganic P. Moderately labile organic P was the main form in the organic P, accounting for 70.14% of the total organic P. With the increasing of planting years, the differences of total P content was significant, but the variation tendency of total P content was not obvious. Available P, Al-P and Fe-P increased significantly, and total organic P, moderately labile organic P, moderately resistant organic P and highly resistant organic P decreased significantly. Available P was significantly or very significantly correlated with Ca-P, Fe-P and Al-P. The largely accumulated P consisted of Ca-P, Fe-P and Al-P, which had higher availability to crop.
