摘　　要：江西省安福县在2009年早稻和晚稻上开展了水稻"三控"施肥技术对比试验,结果表明,采用三控施肥技术比习惯施肥法增产,且节省肥料成本。三控施肥技术增产、增效的主要原因是有效穗或每穗总粒数、结实率比习惯施肥法增加,其中早稻每穗总粒数、结实率分别比对照增加6.19%和2.91%,晚稻有效穗、结实率分别比对照增加7.50%和5.13%。Jiangxi Province Anfu County in 2009 early rice and late rice launched rice ＂Three Controls＂ fertilization contrast test results showed that three control fertilization technology than fertilizer practice to yield and save fertilizer cost.＂Three Controls＂fertilization technology increase output main reason was effective panicle or per panicle,seed setting rate than fertilizer practice increase,early rice per panicle,setting rate were increased 6.19% and 2.91%,late rice effective panicle,setting rate were increased 7.50% and 5.13%.
