摘要:
连阴雨是长江中下游地区小麦生产面临的主要气象灾害,渍水(渍害)和寡照(阴害)2种胁迫作用,是造成该地区小麦减产的主要原因。为定量研究渍水和寡照及其协同作用对小麦产量构成的影响,本研究选取该地区常见的小麦品种宁麦13和扬麦13号,在拔节期和灌浆期,设置对照、渍水、寡照和渍水+寡照4种处理,以及3种不同胁迫持续时间(5、10、15 d)的盆栽试验,观测不同处理对小麦产量构成的影响。结果表明,未发生胁迫作用情况下,扬麦13号的产量高于宁麦13。拔节期宁麦13对渍水和寡照的耐受性要高于扬麦13号,灌浆期宁麦13和扬麦13号对渍水和寡照的耐受性相近。此外,拔节期不同胁迫对小麦造成的减产呈现为渍水>渍水+寡照>寡照,表明寡照在拔节期对渍水胁迫存在补偿作用,而灌浆期不同胁迫对小麦造成的减产呈现为渍水+寡照>渍水>寡照,表明灌浆期寡照对渍水胁迫存在叠加作用。结果表明,连阴雨造成小麦减产与小麦所处生育期有关,建立小麦生长模型渍害和阴害模块时,应考虑小麦所处生育期对其产量构成影响的差异。
