摘　　要：以杂交中籼Y两优17为材料,选择噁草酮作“播喷同步”封闭除草剂。以手工栽插超高产栽培的Y两优17为对照,研究“播喷同步”机械精量穴直播技术在安徽沿江稻区杂交中籼稻上的应用效果。结果显示,机械精量穴直播栽培具有播种精度高、播种均匀、播种与封闭除草同时进行、田间操作方便、劳动力用工和强度较低等优点,而且能省种省水、提高产量,在安徽沿江稻区具有较好的应用前景。机械精量穴直播栽培Y两优17全生育期131d,有效穗278.00万/hm^2,每穗总粒数203.83粒,结实率90.53%,千粒重23.34g。与手插栽培相比,机械精量穴直播栽培技术Y两优17的生育期缩短、有效穗较多而穗型略小,其产量12.05t/hm^2,比手工栽插技术增产5.24%。With Indica rice Y Liangyou 17 as the research mateiral,oxadiazon was used as the blocking herbicide for sowing and spraying synchronously.With manual cultivated Y Liangyou 17 as the control,we researched the application effects of mechanical precision hole direct seeding technology of sowing and spraying synchronously in Indica rice in Anhui rice planting area along the river.Results showed that mechanical precision hole direct seeding technology had the advantages of high precision,even sowing,synchronous sowing and spraying,convenient field opreation,low labor use and strength,besides it could save water and seed and enhance the yield,which had relatively good application prospect in Anhui rive planting area along the river.The whole growth period of Y Liangyou 17 by mechanical precision hole direct seeding technology was 131 d,the effective ears were 278.00×10^4/hm^2,grains per ear was 203.83,seed-setting rate was 90.53%and 1 000-grain weight was 23.34 g.Compared with manual cultivation,Y Liangyou 17 cultivated by mechanical precision hole direct seeding technology had the characters of shorter growth period,more effective ears and smaller ear shape.Its yield was 12.05 t/hm^2,which was 5.24%higher than that of manual cultivation.
