可以相互混合的化肥有: 一、铵态氮肥与化学酸性肥料 铵态氮肥是指含有NH_4~+的N素化肥,如碳酸氢铵、硫酸铵、氯化铵、氨水等。目前使用的化学酸性肥料主要指过磷酸钙。如将碳酸氢铵与过磷酸钙混沤,在混合时会发出一种咝咝的响声,就是相互作用生成磷酸二氢铵,而过磷酸钙中的游离态的磷酸和硫酸得到了中和,有利于提高磷素的有效性。实践证明,
Fertilizers can be mixed with each other are: First, ammonium nitrogen and chemical fertilizer acidic ammonium nitrogen fertilizer refers to contain N_4 + N fertilizer, such as ammonium bicarbonate, ammonium sulfate, ammonium chloride, ammonia and so on. Currently used chemical acid fertilizers mainly refers to superphosphate. Such as ammonium bicarbonate mixed with superphosphate, when mixed will emit a sobbing sound, that is, the interaction of ammonium dihydrogen phosphate, and the superphosphate free phosphoric acid and sulfuric acid have been neutralized, there Help to improve the effectiveness of phosphorus. Practice shows that,
