摘要
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。
Plot and field tests were conducted in the calcareous soils to study the applylng effects of monoammonium orthophosphate (MAP) on malting barley elementally. The results indicated that the grain yield was 8. 41 higher percent and the fertilizer cost 6. 02 percent lower by alpplying MAP than by applying diammonium orthophosphate and lower cocentrated mixed fertilizers. The optimum amount of fertilizers pplied on malting barley was 15kg MAP and 10. 5kg N per mu respectively.
