| 摘 要： | 利用培养及微区试验研究P肥施用潮褐土后的动态转化及其影响因素表明,施肥初期土壤中除难溶性Ca10-P外,各无机P组分均有不同程度地提高,随着时间的延续各组分间的相互转化呈一定规律。种植作物直接影响P肥动态转化的方向。

| Abstract: | Incubation and micro-field plot experiment were carried out to study the transformation and its influence factors of applied P in the meadow-cinnamon soil in Hebei Province.The results indicated that all the other inorganic phosphorus factors were formed except Ca10-P in the initial stage of application,but with the process of time,there is a law of transformation among these factors.Planting crops seriously affected the transformation of applied P. |
