摘  要:
通过室温培养—盆栽试验 ,研究施用猪粪和磷肥 (磷酸二氢钾 )后黄潮土速效磷和有机磷组分的变化、不同有机磷组分的有效性以及磷的利用率。结果表明 ,施用猪粪和磷肥能显著提高土壤速效磷水平 ,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。

摘  要:
Incubation of pig slurry at room temperature and pot experiments on 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 highestUtilization rate of phosphorus was low because of the strong immobilization of phosporus by fluvo-aquic soil.
