| Abstract: | The experimental result showed that the suitable seeding time was from 25to30 April, the density was 180-225 thousand holes/hm 2, the time of top-dressing at tillering was from seventh to tenth day after transplanting, the midsummer drainage started when the rate of number of panicle to total seedling was 80%-90%. N-fertilizer was 40 kg/hm 2 as top dressing at young spike formation stage, with the application of phosphorus and potassium fertilizer, to reach high rate of seed-setting and high 1000-seed weight. |
