摘　　要：为探索不同有机肥替代化肥比例对水稻农艺性状及产量的影响,寻找最适合普安县的水稻施肥方案,开展了不同有机肥替代比例的随机区组试验,设4个不同处理,分析不同处理对水稻株高、穗长、有效穗数、每穗结实粒、结实率和千粒质量等农艺性状及产量的影响。结果发现,T2处理水稻农艺性状最好,产量最高,为553.06 kg/667 m^(2),比T1处理增产29.84 kg/667 m^(2),认为T2处理适宜在普安县推广使用。To explore the effects of different proportions of organic fertilizer instead of chemical fertilizer on rice agronomic traits and yield,and to find the most suitable local rice fertilization scheme in Pu'an County.A randomized block experiment with four different treatments was conducted.The effects of different treatments on the agronomic traits such as plant height,panicle length,effective panicle number,grains per panicle,seed setting rate and 1000-grain weight,as well as yield of rice were analyzed.The results showed that the agronomic traits of rice in treatment T2 were the best and the yield was the highest,reaching 553.06 kg/667 m^(2),which was 29.84 kg/667 m^(2) higher than that in treatment T1.It was considered that treatment T2 was suitable for promotion and application in Pu'an County.
