摘要:
目的 水稻是我国最重要的口粮作物。明确气候变暖对双季优质稻产量和稻米品质的影响对我国粮食安全至关重要。方法 采用稻田开放式远红外主动增温系统,早稻以金早47(常规籼稻)、两优287(杂交籼稻),晚稻以象牙香珍(常规籼稻)、万象优华占(杂交籼稻)和甬优5550(杂交粳稻)为材料,设置全生育期增温和全生育期不增温2个处理,分别测定双季优质稻的产量、产量构成和稻米品质。结果 与不增温相比,全生育期増温(1.3℃ ~1.6℃)对早晚籼稻产量影响不显著,但晚粳稻产量显著下降,降幅为10.2%,主要是因为其每穗粒数下降。全生育期增温降低了早晚稻株高;早稻生育期缩短了3~4 d,而晚稻生育期无明显变化。全生育期增温下,双季优质稻米垩白粒率和垩白度显著增加,早稻两优287出糙率和整精米率及晚粳甬优5550整精米率显著提高;同时,晚稻蛋白质含量提高,但晚粳直链淀粉含量降低,而早稻蛋白质和直链淀粉含量无明显变化;此外,稻米RVA谱特征值因季别和品种而异。结论 全生育期增温对优质晚粳稻产量影响大于籼稻,不利于外观品质的保优,但有利于改善优质稻米加工品质,对晚稻营养品质和食味品质的影响也大于早稻。
