三亚市水稻氮磷钾肥利用率田间试验探析

Sanya City Field Experiment Analysis of Nitrogen,Phosphorus,and Potassium Fertilizer Utilization Rate in Rice

海南省三亚市是中国南繁育种基地之一,水稻为全市的主要粮食作物,在生产过程中合理施用肥料以提高产量极其重要。本试验通过田间水稻种植试验和实验室检测及数据分析,探讨氮肥、磷肥、钾肥不同配施水平对水稻产量及肥料利用率的影响。结果表明,测土配方施肥的水稻产量最高,处理1的理论产量为558.04 kg/667m^(2),氮肥利用率为41.37%、磷肥利用率为22.73%、钾肥利用率为45.84%。本试验旨在为三亚市水稻种植中推广测土配方施肥技术提供数据支撑和参考。

Sanya City, Hainan Province, is one of China's southern breeding bases, and rice is the city's main food crop, so it is crucial to rationally apply fertilizers in the production process to improve the yield. This experiment explored the effects of different levels of nitrogen, phosphorus, and potassium fertilizers on rice yield and fertilizer utilization through field rice planting tests, laboratory tests, and data analysis. The results showed that the highest rice yield was achieved with soil testing and formula fertilization, and the theoretical yield of treatment 1 was 558.04 kg/667m^(2), with the utilization rate of nitrogen fertilizer at 41.37%, phosphorus fertilizer at 22.73%, and potash fertilizer at 45.84%. This experiment aims to provide data support and reference for soil testing and formula fertilization technology promotion in rice cultivation in Sanya City.
