摘　　要：对杂交中稻丰两优香1号进行不同播期、密度、施氮量和水分4因素3水平的正交试验,筛选其最佳栽培因子组合。结果表明,播期和施氮量是影响中稻生育进程和产量的主要因素;播期对中稻生育期影响显著,对产量影响极显著,施氮量对中稻产量影响极显著;中稻高产栽培的最佳组合的播期为5月1日、大田栽插秧苗密度为60万苗/hm2、施氮量为121.6kg/hm2、水分为10cm水层。An orthogonal experiment with four factors and three levels of sowing date, planting density, fertilizer rate and field water was conducted to screen the best combination of cultural factors for medium rice Fengliangyouxiang 1. The result indicated that sowing date and fertilizer rate were the main influence factors on the growth period and yield of medium rice. Sowing date had a significant effect on growth period and a very significant effect on the yield. Fertilizer rate had a very significant effect on yield. The best combination of cultural factors for Fengliangyouxiang 1 was, sowing date,1 May, planting density, 600 000/hm^2; fertilizer rate, 121.6 kg/hm^2; and field water, water depth of 10cm.
