| 摘 要： | 利用培养及微区试验，研究磷肥施入潮褐土后的动态转化及其影响因素。结果表明：施肥初期，除土壤中难溶性Ca10-P外，各无机磷组分均有不同程度的提高，随着时间的延续，组分间的相互转化呈一定规律。种植作物直接影响着磷转化的方向。

| 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 Ca 10 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 |
