作者杨程,张德奇,时艳华,李向东,张素瑜,邵运辉,方保停,岳俊芹（2019）在《不同灌水处理对不同抗旱型小麦品种生长发育和产量的影响》一文中研究指出：为了探明黄淮麦区不同干旱敏感型冬小麦品种对不同灌溉方式的响应特征,以黄淮麦区大面积推广的2个冬小麦品种抗旱型的矮抗58(AK58)和干旱敏感型的郑麦7698(ZM7698)为研究对象,在隔离池中通过不同时期定量灌水研究总灌水量不变的情况下拔节期和开花期水分调配对2个小麦品种的群体数量、个体发育、产量构成的影响。结果表明,ZM7698在拔节期灌水100 mm+开花期灌水100 mm(B1F1)处理下具有最高的群体数量和次生根数,而AK58在拔节期灌水200 mm+开花期不灌水(B2F0)处理下群体数量和次生根数最高;2个小麦品种均在B2F0处理下株高最高,B1F1和B0F2(拔节期不灌水+开花期灌水200 mm)处理株高均较其显著下降。与B2F0处理相比,B1F1和B0F2处理ZM7698和AK58两个品种旗叶SPAD值均显著下降,ZM7698叶片SPAD值下降幅度大于AK58。ZM7698和AK58的小穗孕性对不同灌水处理的响应明显不同,ZM7698结实小穗比率表现为B0F2>B1F1>B2F1,AK58则表现为B1F1>B0F2>B2F0。AK58的产量表现为B1F1>B2F0>B0F2,穗数表现为B2F0>B1F1>B0F2,穗粒数表现为B1F1>B2F0>B0F2,千粒质量表现为B0F2>B1F1>B2F0;而ZM7698的产量则表现为B1F1>B0F2>B2F0,穗数表现为B2F0>B1F1>B0F2,千粒质量表现为B0F2>B1F1>B2F0,穗粒数表现为B2F0>B0F2>B1F1。AK58和ZM7698的强势粒千粒质量均随着开花期灌水量的增加而显著增加,但AK58的增加幅度明显高于ZM7698; ZM7698弱势粒千粒质量仅在B1F1和B0F2处理间有显著差异,而AK58弱势粒千粒质量在B1F1和B0F2处理下均显著高于B0F2处理。综上所述,抗旱型品种AK58和干旱敏感型品种ZM7698均在拔节—开花期均匀灌水(B1F1)条件下产量最高,但是产量构成因素变化不同,AK58和ZM7698小穗发育过程和强、弱势粒灌浆过程对拔节期和开花期土壤水分敏感性的不同是造成2个小麦品种产量构成不同的重要原因。
