摘  要:
通过肥料的沙柱淋溶性试验,研究了以亚铵法制浆蒸煮废液氨解产物为原料研制的木质素肥料的缓释特性。试验结果表明,利用亚铵法制浆蒸煮废液氨解产物研制的复合肥具有较低的溶出率,能延缓氮素的释放速度,并且呈现出随着氨解产物用量的增加肥料抗淋溶能力增强的趋势。因此,亚铵法制浆蒸煮废液氨解产物可用于研制缓释肥料。

摘  要:
Through the leaching experiment, this paper studied on the slowly releasing characteristics of lignin compound fertilizer which was made of ammonia products of ammonia sulfite pulp black liquid. The result showed that the fertilizer had lower dissolving rate and could decrease the releasing spread of nitrogen, demonstrating the trend that with the increasing of the products of the ammonification, the agaist leaching ability of the compound fertilizer strengthened fertility. So, ammonia products of ammonia sulfite pulp black liquid can be used to prepare slowly releasing fertilizer.
