补充资料：水稻季节生态型(seasonal ecotypes of rice)
| 水稻季节生态型(seasonal ecotypes of rice) 根据稻种对温光反应的不同，而划分的适于不同季节生长的生态型。由于水稻对温度和光照反应的多样性，不论籼稻和粳稻都可分为早、中、晚稻三种季节生态型。每种季节生态型又可根据熟期早晚分为早、中、迟熟三类。 晚稻为生育期较长，成熟季节较迟的类型，其感光性强，需要有晚秋时期的短日照条件方能出穗晚稻是由野生稻演化而形成的基本型，而早稻和中稻是由晚稻在温度较低和日照较长环境下形成的变异型。晚稻成熟时正值秋季，白天温度较高，夜间温度较低，有利于稻穗灌浆成熟，稻米品质往往较优良。 中稻是生育期中等，在早秋季节成熟的类型。大多中粳品种感光性中等，短日高温生育期多数较短、少数为中。由于中粳感光性中等，出穗日数因地区和播期不同而变化较大。由于中籼感光性弱，短日高温生育期中至长，各地播种至出穗日数变化较小而相对稳定，因而品种适应范围广，可在亚热带和热带地区之间相互引种。 早稻是生育期较短、成熟季节较早的类型。东北的一季粳稻以及长江以南稻区双季稻中第一季早、中熟品种多属于早稻类型。由于早稻感光性弱，只要温度条件能够满足水稻生育，无论在长日照或短日照条件下均能正常出穗成熟。 |
