利用沸石较强的阳离子交换性和吸附性特点，将其用作氮肥硝酸铵载体，采取土壤表施和深施，定期测定土壤氮素含量，研究其动态变化。结果表明，采用载体处理在土壤中对氮素的保存率随时间的延长而提高，３０ｄ试验期全氮含量比同期对照提高５％～８７．５％，水解氮含量比同期对照提高０．８５％～４２．６％。据此认为，采用沸石载体处理氮肥，对提高其肥效和延长土壤供肥期及减少氮肥在施入土壤后的损耗具有明显作用。
The zeolite was used as nitrogenous fertilizer ammonium nitrate carrier by virtue of strong cation exchangeability and adsorption characteristics of the zeolite, soil nitrogen application and soil nitrogen content were measured periodically to study the dynamic changes. The results showed that the retention rate of nitrogen in the soil increased with the increase of time. The content of total nitrogen increased by 5% -87.5% over the same period and the content of hydrolyzed nitrogen increased by 0.85 % ~ 42.6%. Therefore, the use of zeolite carrier treatment of nitrogen fertilizer, to improve its fertilizer efficiency and extend soil fertilization period and reduce the nitrogen fertilizer in the soil after the loss has a significant role.
