摘要
对不同生态类型的２０个小麦品种进行了多效唑浸种和喷施研究。结果表明，用多效唑浸种能促进小麦苗期生长，加快叶片和分蘖的发生。品种间效应基本一致，对晚茬小麦有普遍应用价值。返青至拔节期喷施延缓效应强烈，大多数品种株高降低，茎壁变厚，抗倒伏能力增强，抽穗期和成熟期延迟。同时，穗部性状发生较大变化，大多品种穗粒数增加，千粒重降低，品种间效应差异树显著。对旺长麦田喷施多效唑能防止倒伏，对一般不发生倒伏的麦田，大多品种有减产效应。
Twenty wheat varieties of different ecological types were studied in this paper byflooding and spraying MET.The results showed that using MET flooded seeds canenhance the growth of Seedling date and quicken the appearance of the leaf and tiller.Effects between varieties were basically the same,and flooded seeds were useful for laterplanted Wheat.The delayed spraying effect was stronger at greening to jointing stage.Plant height of most varieties was lowered.and the heading date and mature date were putoff.The ear haracteristic changed significantly, most varieties increased in grain number,but the 1000-grain weight decreased,effect between varieties reached extremtly significantdifference.Spraying MET to over-strong wheat can prevent lodging and increase the yield,however,to most unlodging varieties,the yield decreased.
