摘要： 对杂交中稻丰两优香1号进行播期、栽插密度、施N量和水分的正交试验，探讨不同栽培因素组合对杂交中稻生育期、主要经济性状及产量的影响。结果表明，播期对生育期的影响显著（F=28>F0.05=19.00），在试验水平范围内，随着播期的推迟，其生育期逐渐缩短，施N量、水分和栽插密度对生育期的影响均不显著；N肥施用量、播期是影响水稻产量的关键性因子，对产量的影响分别表现为极显著F=127.3529>F0.01和显著（F=62.8117>F0.05）。丰两优香1号高产栽培的最佳组合为A2B2C3D1。

Abstract: Effects of sowing date, density, nitrogen rate and water on growth period, the main economic characters and yield of medium hybrid rice Fengliangyouxiang 1 were explored by orthogonal experiment. The results showed that, the effects of sowing date on the growth period was significant（F=28>F0.05=19.00）, within the experimental range, the growth period was shortened with the delay of sowing date; the effects of N fertilizer, water and density on the growth period were not significant; N application rate and sowing date were the key factors affecting the yield of medium hybrid rice, and the effects on yield was extremely significant （F=127.3529>F0.01） and significant （F=62.8117>F0.05）, respectively. The best cultivation measures of Fengliangyouxiang 1 was A2B2C3D1.
