摘要
采用石灰性土壤无机磷分级方法初步探讨了河北省砂质潮土中P肥动态转化及其影响因素。结果表明,施P肥可显著提高潮土中无机磷各组分含量,增施有机肥可改变P素形态间的转化速率及方向。
By method of soil inorganic phosphorus fraction,the dynamic transformation of phosphate fertilizer and its influence factors in meadow soil in Hebei Province is discussed.The results show that the content of inorganic phosphate in meadow soil is improved obviously by phosphate fertilizer supply and the transformation ratio and distribution of phosphorus are changed by increasing organic manure.
