摘要
在普遍尿素的生产工艺中分别加入一定比例的无机矿物改性剂，研制出３种改性尿素。盆栽结果显示，在等质量及等Ｎ施肥条件下，３种改性尿素均有较大幅度的增产。淋溶实验表明，改性尿素与德国缓释尿素的淋溶曲线相似。
In the production process of urea, different proportional inorganic mineral modified additives were added to produce three kinds of modified urea. The pot experiment shows that the three kinds of modified urea have more positive effect on increasing biomass than that of ordinary urea under condition of equivalent mass and N content. Moreover, eluviation experiment shows that the eluviation curves of the three kinds of modified urea are similar to that of slow released urea from Germany.
