| 摘 要： | 采用秧龄与播种量二因素随机完全区组试验,观察不同处理组合的主要农艺性状及产量表现,结果表明：秧龄25 d与30 d的处理有效穗多,每穗粒数多,结实率高,产量显著高于秧龄20 d处理;大田播种量0.75 kg/667m2与1 kg/667m2处理差异不显著;处理组合以秧龄30 d、播种量1 kg/667m2为最高,显著高于秧龄20 d、播种量0.75 kg/667m2和秧龄20 d、播种量1 kg/667m2的处理组合。

| Abstract: | Two factors randomized complete block experiment based on seedling age and sowing rate in double late rice was studied and main agronomical traits and yield performance of different treatment combinations were observed.The results showed that the treatments with seedling age of 25 d or 30 d had more reproductive panicle numbers,more spikelets per panicle,higher seed setting rate,and their yields were significantly higher than the seedling age of 20 d.There was no significant difference in grain yield between the sowing rate of 0.75 kg/667m2 and of 1 kg/667m2 in paddy field.Grain yield was the highest for the combination of seedling age of 30d and sowing rate of 1 kg/667m2,significant higher than that of the combination of seedling age of 20d and sowing rate of 0.75 kg/667m2 or seedling age of 20 d and sowing rate of 1 kg/667m2. |
