Sanya City Field Experiment Analysis of Nitrogen,Phosphorus,and Potassium Fertilizer Utilization Rate in Rice
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 ef-fects 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/667m2,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.
