摘　　要：为筛选出适合晚稻生产的肥料运筹方式,减少肥料成本、增加经济效益,以籼粳杂交晚稻甬优7850为试验材料,研究不同缓释肥料用量及运筹方式对产量、农艺性状及氮素效率的影响。结果表明,等养分处理下,有机无机缓释肥有利于提高有效穗、每穗粒数,667 m^(2)基肥使用30 kg加适量分蘖肥较常规施肥增产4.80%,氮肥农学效率最高;等成本情况下,缓释肥处理氮素减少,产量仍较常规施肥增加1.53%,且氮肥农学效率明显高于常规施肥。双季晚稻有机无机缓释肥以667 m^(2)基肥用量30 kg、总氮量在10.7~12.0 kg为宜。In order to screen out the fertilizer management methods suitable for late rice production,reduce fertilizer cost and increase economic benefits,the effects of different slow-release fertilizer application rates and management methods on yield,agronomic traits and nitrogen efficiency were studied by using indica-japonica hybrid late rice Yongyou 7850.The results showed that under the same nutrient treatment,organic and inorganic slow-release fertilizer was beneficial to increase the effective panicle and grain number per panicle,and the yield of 667 m^(2) basal fertilizer with 30 kg and appropriate tillering fertilizer was 4.80%higher than that of conventional fertilization,and the agronomic efficiency of nitrogen fertilizer was the highest.Under the same cost,the yield of slow-release fertilizer was still 1.53%higher than that of conventional fertilization,and the agronomic efficiency of nitrogen fertilizer was significantly higher than that of conventional fertilization.The organic and inorganic slow-release fertilizer of double-cropping late rice should be 667 m^(2) basal fertilizer with 30 kg and total nitrogen at 10.7-12.0 kg.
