| 摘 要： | 通过盆栽试验,研究以亚铵法制浆废液氨解产物为原料研制的复混肥对土壤脲酶活性的影响,以确定其对肥料缓释性能的影响.试验结果表明,以亚铵法制浆废液氨解产物为原料研制的复混肥,能够抑制土壤脲酶活性,降低氮素的释放速度,从而提高肥料的利用率,旨在以亚铵法制浆废液氨解产物研制缓释混肥提供理论依据.

| Abstract: | The influence of the compound fertilizer which is made of the ammonification of ammonia sulfite pulp black liquid on the soil urease activity. The result of the pot experiment shows that it can suppress the soil urease activity and reduce the releasing speed of N. So it can improve the utilization ratio of the compound fertilizer. |
