1988～1989年系统观察表明,麦后移栽棉移栽期虽然比麦套移栽棉迟8～15天,但生长发育速度快,株高、单株叶面积及生物学产量最终均超过麦套移栽棉;随着生育进程,现蕾、开花期与麦套移栽棉的差距逐渐缩小,吐絮期两者基本一致。此外,麦后移栽棉在一年中温光资源最充沛的7月中下旬到8月中下旬开花、结铃,较麦套移栽棉明显集中,数量也较多,这是麦后移栽棉丰产的重要生理基础。籽棉实产,麦后移栽棉两年均高于麦套移栽棉,其中1988年差异达到5％显著水平.
The systematic observation from 1988 to 1989 showed that although the cotton transplanting cotton after transplanting was later than the transplanting cotton with transplanting cotton for 8 to 15 days, the growth and development speed was fast, the plant height, the leaf area per plant and the biological yield finally surpassed the wheat Set transplanting cotton; With the fertility process, budding, flowering and wheat transplanting cotton gap gradually narrowed, the bolting period of the two basically the same. In addition, transplanting wheat after transplanting cotton in one year, the most abundant light and temperature of resources in late July to late August flowering, boll, transplanting cotton than the wheat significantly concentrated, the number is also more, which is transplanting wheat An important physiological basis for cotton yield. Seed cotton seed production, wheat transplanting cotton two years were higher than wheat transplanting cotton, of which the difference in 1988 reached a significant level of 5%.
