| 摘要: |
| 花铃期土壤湿度对棉纤维伸长与纤维素积累的影响很大，土壤湿度保持328g/kg或将土壤湿度由246g/kg提高到328g/kg，能促进纤维伸长，有利于前期纤维中可溶性糖的增加和后期纤维素的积累；土壤湿度由328g/kg降到246g/kg，抑制纤维伸长，土壤湿度164g/kg，严重影响纤维伸长，可溶性糖含量低，纤维素积累量最少，纤维品质变劣。 |

| Abstract: |
| During the cotton flowering and boll developing stages the extension of fiber and accumulation of cellulose were greatly affected by soil moisture. When soil moisture was maintained at 328 g/kg or increased from 246g/kg to 328g/kg ,it was favourable to promote the extension of fiber and increase the amount of soluble sugar during the early stage as well as to increase the accumulation of cellulose during the late stage of fiber development.On the contrary,when soil moisture was decreased from 328g/kg to 246g/kg ,the extension of fiber was depressed. When soil moisture dropped to 164g/kg ,the extension of fiber was seriously affected;the amount of soluble sugar was lower;and the accumulation of cellulose was the lowest so that the quality of fiber becomes very poor. |
