一、肥料混合的原则。第一,肥料混合后不会产生不良的物理性状;其次肥料养分不受损失,而且还能避免或减轻某些肥料单施用时的不良作用。诸如生理酸性肥料硫酸铵与化学酸性肥料过磷酸钙经混合后产生磷酸二氢铵,施入土壤后,作物能同时吸收,混合后一般堆积两周为度。在混合中不发生化学变化的磷矿粉与硫酸铵,混合后施到土壤中,作物吸收较多的铵离子,通过离子交换,把根系胶体上的氢离子置换到土壤
First, the principle of fertilizer mix. First, there is no adverse physical traits when mixed with fertilizers; secondly, fertilizer nutrients are not lost, and the adverse effects of certain single fertilizers can be avoided or mitigated. Such as physiological acid fertilizers, ammonium sulfate and chemical acid fertilizers superphosphate mixed to produce ammonium dihydrogen phosphate, applied to the soil, the crops can be absorbed at the same time, after the general accumulation of two weeks for the degree. Phosphorite powder and ammonium sulfate, which do not chemically change during the mixing, are applied to the soil after mixing, and the crop absorbs more ammonium ions, displacing the hydrogen ions in the root colloid to the soil by ion exchange
