| 摘 要： | 供试的四个陆地棉品种地上部分干物质累积速度和数量，从现蕾至吐絮始终高于四个海岛棉品种；陆地与棉与海岛棉的所有品种干物质累积速率最快的时间均在初期至有效花期期间。但海岛棉干物质累积最大量到８月２５日止，陆地棉则持续到９月９日；不同时期干 物质分配率的特点是；苗期；叶〉茎，苗期：叶〉茎〉蕾，花苗期：叶〉茎〉铃〉蕾〉花；铃期；铃〉茎〉叶；株铃重累积的最快速率时间，陆地棉与海岛棉均在７月２６日至８月２５日

| Abstract: | The accumulating rates and numbers of dry matter of 4upland cotton(upco) specises were always high than those of 4 seaisland cotton (sico) specises, according to our experiment conductedfrom the budding to the blooming. The highest rate of all the specises-from both types appeared both from the first blooming (June 6) to theuseful blooming (Augnst 10). But the largest amount of accumulating drymatter in sico ended on August 25, while that in upco on September 9. The most rapidly accumulating rates of the cotton boll of both typeswere from July 26 to August 25. The only different between them was thatthe largest amount of accumulating rate of cotton plant in sico was onAugust 10,and the upco on August 25. The dry matter weights of the sicoroot system and flowers were heavier than those of the upco. |
