摘要
研究栽培方法对３∶１式麦套中早熟春棉棉铃发育的影响表明：移栽棉铃重大于直播棉，差异随播期延后而减小；育苗移栽利于纤维伸长和纤维素累积；移栽棉棉籽（仁）脂肪累积优于直播棉。棉仁棕榈酸、油酸、硬脂酸含量稳定，栽培方法和播期对其影响较小；移栽棉、直播棉棉仁亚油酸含量随播期延后均递增，适时播种利于棉籽（仁）蛋白质累积，栽培方法间差异较小；晚播时移栽棉优于直播棉，但不利于蛋白质累积。３∶１式中麦套早熟春棉应选择育苗移栽方法。
The results of this research showed that the boll weight with the cultivation methods of seedling transplanting was greater than with field cultivation methods.The difference could be narrowed as the seedling period was put off.The seedling transplanting method benefited the fiber elongating and fiber cellulose accumulating.The palmitic acid,oleic acid and sterine acid contents in kernel were stable,and the cultivation methods and seedling period affected it slightly.The linoleic acid contents increased as seedling period postponed.Earlyseedling at the right moment was beneficial to cotton seed (kernal) protein accumulation.Under the condition of late seedling,the seedling transplanting cotton was prior to the field cultivation,but not benefit to the cotton seed (kernal) protein accumulation.As to the double maturity spring cotton with earlymiddle maturity variety,the seedling transplanting method should be adopted with the 3∶1 model.
