摘　　要：以‘济优6587’为试验材料,设置了不施肥、常规施肥、常规施肥+减氮5%、缓释肥+减氮10%、缓释肥+减氮20%5个处理,比较不同处理水稻产量、经济效益和土壤养分含量。结果表明:不同施肥方式对水稻产量及种植经济效益、土壤养分含量存在显著影响。综合考虑各个因素,认为采用缓释肥替代普通氮肥并减氮10%时,水稻产量及种植经济效益最高,是最适宜浏阳市的水稻种植施肥模式。This study used the variety'Jiyou 6587'as the experimental material and established five treatment groups:no fertilizer,conventional fertilization,conventional fertilization with a 5%nitrogen reduction,controlled-release fertilizer with a 10%nitrogen reduction,and controlled-release fertilizer with a 20%nitrogen reduction.The aim was to compare rice yield,economic benefits,and soil nutrient content across these treatments.The results indicated that different fertilization methods significantly impacted rice yield,planting economic benefits,and soil nutrient content.Considering all factors comprehensively,.,it was concluded that when slow-release fertilizer was used to replace ordinary nitrogen fertilizer and reduce nitrogen by 10%,the rice yield and planting economic benefits were the highest,and it was the most suitable rice planting and fertilization mode in Liuyang City.
