| 摘 要： | 以单季杂交晚籼稻Y两优689为试验材料,研究不同移栽期(水稻4叶、5叶、6叶、7叶、8叶期)对水稻产量及产量构成因子的影响。结果表明:Y两优689产量随着叶龄的增加呈下降的变化趋势;在水稻4叶期移栽,Y两优689产量最高,其产量可以达到10231.8kg·hm-2。

| Abstract: | A field experiment was conducted with different transplanting date （4,5,6,7,8 leaf stage）by using single cropping rice, Y Liangyou 689 as material, exploring the best planting pattern. The results indicated that the yield of Y Liangyou 689 decreased as the transplanting date delayed; Under the transplanting date of 4 leaf stage,grain yield was the highest, up to 10 231.8 kg·hm-2. |
