| 摘 要： | 以杂交稻II优818为材料,通过对水稻不同灌溉方式下分蘖成穗规律的定点考察,明确了水稻好气灌溉的高产原理及其分蘖组成与常规灌溉有很大差异。水稻好气灌溉带3叶以上的分蘖比例明显高于常规灌溉,而3叶以上的分蘖成穗率高,成穗数多,形成的穗型大,构成了水稻好气灌溉的高产结构。 |
| 关 键 词： | 水稻 好气灌溉 成穗规律 高产机理 |

| Abstract: | The experiment of different water managements was carried out by inspecting rice plants in the same site in farmer's field at Xianju in Zhejiang,used hybrid rice(II you 818) as material in the experiment.The results showed: it was very different from tillering components under different water managements.The tiller number with more than 3 leave was more than traditional irrigation under aerobic irrigation.It showed more panicles and grains and higher yield under aerobic irrigation than aerobic irrigation. |
| Keywords: | rice(Oryza sativa L ) aerobic irrigation tiller and panicle mechanism of high-yield |
