摘　　要：研究了不同秧龄和播种量对中优281产量的影响。结果表明,秧龄和播种量对产量均有显著影响,秧龄在25、30、35d范围内,秧龄越短,产量越高;播种量在0.15～0.45t/hm2范围内,播种量越小,产量越高,秧龄25d与播种量0.15t/hm2是本试验的最佳处理组合。Effects of different seeding rate and seedling age on yield of Zhongyou 281 were studied in this paper. The results showed that yield was significantly affected by seeding rate and seedling age： when seedling age in the range of 25, 30 and 35 days, the younger the seedling age, the higher the yield; when the seeding rate was in the range of 0.15 - 0.45 t/hm^2, the less the seeding rate, the higher the yield. The optimum treatment was seedling age of 25 days combined with seeding rate of 0.15 t/hm^2.
