| 摘 要： | 随着水稻不断生长发育,其需水量也在不断变化,不同的灌溉方式直接影响到水稻中后期的生长发育.通过试验可确定灌溉的雏模式为:分蘖始期进行浅水(3～0 cm)灌溉;有效分蘖期可进行浅湿交替灌溉;分蘖末期进行落干晒田,以培育水稻后期健壮的根系;孕穗期和抽穗开花期应保持3 cm左右水层,能提高分蘖成穗率,保证枝梗和颖花的正常发育,促进穗大粒饱,达到优质、高产的目的. |

| Abstract: | Rice water requirement changes with its growth.The different irrigation affected the rice growth in the middle and late period immediately.The model of irrigation could be determined from this experiment:taking shallow irrigation(0~3 cm) at the beginning of tillering,taking shallow-wet alternating irrigation at the active tellering period,and taking field dry at the end of tellering to make the rice root strong.The water level should be kept at 3 cm about.That will lead to a high spike rate of tiller,a norm... |
