摘　　要：以熔融磷钾肥为基础设计了水稻专用肥,在黑龙江寒地水稻和江苏省一季中稻上进行多点田间试验。结果表明,水稻专用肥较常规施肥平均增产7.6%,氮肥增产效率提高5.8 kg/kg,氮肥利用率提高8.6百分点。Based on fused phosphate potassium tertilizer as basic ior designing the nce speclatty iernuzer, the field tests on Heilongjiang Province cold region rice and Jiangsu Province middle-season rice are carried out. The results show that： compared with common fertilization, the yield of rice with specialty fertilizer increases average 7.6%, the production efficiency of nitrogen fertilizer increases 5.8 kg/kg, the utilization rate of nitrogen fertilizer increases 8.6 percentage points.
