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Ca1 0 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。
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
