摘    要:通过室温培养一盆载试验,研究施工用猪粪和磷肥(磷酸二氢钾)后黄潮土速效磷和有机磷组分的变化,没有机磷组分的有效性以及磷的利用率,结果表明,施用猪粪少磷肥能显著提高土壤速效效磷水平,并增加活性,中活性,中稳性有机磷的含量,其中,以中活性有机磷增量最大,黄潮土对磷的固定能力强,故其磷的利用率较低。

关 键 词:黄潮土 猪粪 磷肥 速效磷 有机磷 组分 有效性 磷素利用率

Effects of Pig Slurry andPhosphatic Fertilizer on Available Phosphorus

Abstract:Incubation of pig slurry at room temperature and pot experimentson ryegrass were conducted to study the changes of available phosphorus and organic P composition in two kinds of fluvo-aquic soils after the application of pig manure and phosphatic fertilizer.The content of available P was increased markedly,and the contents of active organic P,moderately active organic P and moderately stable P were enhanced.Among them,the increment of moderately active organic P was the highest.Utilization rate of phosphorus was low because of the strong immobilization of phosporus by fluvo-aquic soil.
