【摘要】 为研究不同磷肥用量对欧李产量和品质的影响，本试验设置了不同梯度的磷肥用量，包括常规施肥（CK）、磷肥减施1/3、磷肥减施2/3、不施磷肥4个处理。结果表明，磷肥减施1/3处理的欧李产量最高，达14 753.17 kg/hm²，较CK提高了3.55%。欧李的单株有效果和维生素C含量随磷肥施用量的减少而减少；而单宁含量呈先升高后下降的趋势；花青素、总酚和类黄酮变化规律一致，磷肥减施1/3时含量均最高。磷肥用量减少，提高了磷肥施用的农学效率和偏生产力。磷肥减施1/3处理下欧李生产利润最高，达32 277.34元/hm²，利润率高达36.46%。综上所述，在保证产量和品质的情况下，磷肥推荐用量（纯P₂O₅）为150 kg/hm²。更多还原

【Abstract】 In order to study the effects of different phosphate fertilizer rates on the yield and quality of Prunus humilis, this experiment set up different dosage of phosphate fertilizers, including conventional fertilization（CK）,phosphorus reduction by 1/3, phosphorus reduction by 2/3 and no phosphorus application. The results showed that the phosphorus reduction by 1/3 treatment had the highest yield of P. humilis, reaching 14 753.17 kg/hm², which was 3.55% higher than CK. The effectiveness and VC content of single plant of P. humilis decreased with the decrease of phosphorus fertilizer application amount, whereas tannins decreased first and then increased; and anthocyanins, total phenols, and flavonoids all present similar patterns. Agronomic efficiency and partial productivity of phosphate fertilizer application were improved by reducing phosphorus application. When phosphorus application was reduced by 1/3, the profit was the highest, reached 32 277.34 yuan/hm², and the profit rate was as high as 36.46%. Therefore, the recommended dosage of phosphate fertilizer（P₂O₅） was 150 kg/hm² under optimal yield and quality.更多还原
