摘　　要：为研究配方施肥对水稻产量及养分吸收的影响。设置3个田间施肥处理,分析不同施肥处理下水稻产量、农艺性状以及稻谷、稻秆养分含量。结果表明,配方施肥(N_(2)K_(2)P_(2))产量最高(7437.6 kg/hm^(2)),稻秆全氮含量最高(0.72%),稻米中氮、磷、钾含量最高(1.49%、0.35%、0.19%),因此,在海口水稻生产实践中,建议采用配方施肥替代常规施肥。To research the effects of formula fertilizer on rice yield and nutrient absorption.Three field fertilization treatments were established to analyze rice yield,agronomic traits,as well as nutrient content in rice grains and straw under different fertilization treatments.The results showed that the formula fertilization(N_(2)K_(2)P_(2))had the highest yield(7437.6 kg/hm^(2)),total nitrogen of rice straw(0.72%),the content of N.P.K(1.49%,0.35%,0.1%)in rice.Therefore,it is suggested to use formula fertilization treatment instead of conventional fertilization in rice production in Haikou.
