园林肥料在施用过程中,应该搞清楚哪些肥料能混施,哪些不能混施。碳铵与过磷酸钙混合施用,能使作物吸收到氮、磷等营养元素的同时还可中和过磷酸钙中一部分游离酸,消除其危害。但应注意,两者混合比例要适当,pH值保持在微酸性至中性,不可呈碱性,否则过磷酸钙 Garden fertilizer in the application process, we should find out which fertilizers can be mixed, which can not be mixed. Ammonium bicarbonate mixed with the application can enable crops to absorb nitrogen, phosphorus and other nutrients at the same time can also be part of the superphosphate free acid and eliminate its harm. However, it should be noted that the mixing ratio between the two should be appropriate, the pH value remains slightly acidic to neutral, can not be alkaline, or superphosphate
