| 摘 要： | 通过对海岛棉和陆地棉叶片营养元素含量测定值的分析,结果显示海岛棉对氮、钾的需求低于陆地棉，对磷、锰、铜、镁的需求高于陆地棉。海岛棉苗期对铜、硼，蕾期对磷、锌、铜，花铃期对镁、锰、铜的需求高于陆地棉。在生育后期，海岛棉叶片养分含量动态变化与陆地棉有差异。因此，在农业生产中海岛棉与陆地棉的施肥方法应有所区别。

| Abstract: | Nutrition in leaves of sea-island cotton and upland cotton was analyzed, the results showed that the content of N,K in leaves of sea-island cotton was less than that of in upland cotton,the Mn,Cu,Mg was more than that of in upland cotton The volume of absorb of Cu, B in seeding stage and of P,Zn,Cu in bud stage and of Mg,Mn,Cu in flowering and fruiting stage in sea-island cotton were more than that of in upland cotton, and, this difference was lasting to the later stage, so in practical manuring we shonld adopt different methods |
