研究和生产混(复)合肥料已成为化肥工业的一个重要发展方向。特别是根据国内当前肥料工业现状,充分利用现有的肥料品种和原料来发展我国自己特有的混(复)合肥料,更会有其现实意义。我们研究利用碳铵与干制普钙(经一定温度干燥、磨细)配制氮磷混合肥料就是从这一实际出发的。经试验证明,这两种肥料混合不仅增加碳铵稳定性,而且防止了碳铵结块;1980年又经河北省栾城县农技站的200多亩小麦地的肥效试验,得到10％的增产效果。本文为给氮磷混合肥料生产提供理论依据,采用化学分析法测定了混肥中重要成分,並应用这些数据对碳铵与干制普钙混合后发生的反应机理进行了初步探讨。
Research and production of mixed (complex) Hefei feed fertilizer industry has become an important direction of development. In particular, according to the current status of fertilizer industry in our country, it is more practical to make full use of existing varieties and raw materials of fertilizers to develop our own unique mixed (complex) Hefei. We study from the use of ammonium bicarbonate and dried calcium (by a certain temperature drying, grinding) to formulate nitrogen and phosphorus fertilizer is based on this reality. The test proved that the two kinds of fertilizer not only increase the stability of ammonium bicarbonate, but also to prevent the ammonium bicarbonate agglomeration; in 1980 and by Luancheng County, Hebei Province Agricultural Science and Technology Station 200 acres of wheat fertilizer test, get 10% Increase production efficiency. In order to provide a theoretical basis for the production of nitrogen and phosphorus fertilizer, the chemical composition was determined by chemical analysis, and the reaction mechanism after the mixture of ammonium bicarbonate and dried calcium was studied by using these data.
