在石灰性土壤条件下通过田间小区和大区试验初步研究了磷酸一铵在啤酒大麦上的应用效果。结果表明，与磷酸二铵和低浓度混合肥相比，磷酸一铵作基肥效果显著，且成本较低，平均增产8．41％，而肥料成本降低6．02％。啤酒大麦的最佳经济施肥量宜为磷酸一铵15kg／亩，配合纯氮10．5kg／亩。
The application of monoammonium phosphate on beer barley was preliminary studied in field soil and large area under calcareous soil conditions. The results showed that compared with DAP and low concentration fertilizer, monoammonium phosphate had a significant effect of basal fertilizer with lower cost, with an average yield of 8.41% and a decrease of 6.02% of fertilizer cost. The optimal amount of economic fertilizer for beer barley should be 15kg / mu of monoammonium phosphate and 10.5kg / mu of pure nitrogen.
