| 摘 要： | 通过播墒、灌水次数、播期对棉花的生长发育和产量的影响进行研究.结果表明,低播墒明显降低出苗率、叶面积指数、干物质数量,延迟现蕾及结铃时间,减产作用明显.棉花生长期长势良好,产量主要靠一水和二水来完成.播墒低,棉花早期长势偏弱,增加灌水次数增产作用明显.晚播可延长营养生长的时间,增大叶面积指数、延迟现蕾、集中结铃作用明显. |
| 关 键 词： | 棉花 播墒 播期 灌水次数 产量 |

| Abstract: | The study of influence of sowing humidity,irrigation and sowing time on the growth and yield of cotton was carried out in this paper.The result showed that the lower sowing humidity had significant influence on the rate of germination,the leaves area index,the accumulation of dry-matter.The cotton grows well with high yield mainly by first and second irrigation.Yield was increased by rising number of irrigation times.When sowing time was later,the nutrition growth period was prolonged,the leaf area index wa... |
| Keywords: | cotton sow humidity sow time irrigation times yield |
