| 摘要: |
| 对滴灌条件下夏棉水肥耦合效应进行了田间试验，结果表明，根据夏棉不同生育阶段的需水特征和土壤水分状况可分别采用滴灌和畦灌方式，比常规棉田畦灌节水２３．３％～２８．７％，对于中等肥力的棉田，在每ｈｍ＾２施纯氮３００ｋｇ的范围内，随施肥量增加皮棉产量呈增加的趋势，在每ｈｍ＾２施纯氮１５０～２２５ｋｇ区间内，其产量增加较快。 |

| Effects of Water-fertilizer Coupling on Cotton Yield Under Drip Irrigation |
|
|
|
| Abstract: |
| To identify the relations between the water-fertilizer coupling and the cotton yield, the field tests are conducted. The results show that there are 23. 3% to 28.7% of water can be saved by using border and drip irrigation compared with the simple border irrigation. The cotton yield per hectare will be increased quickly when the quantity of N-fertilizer is in the range of 150 kg .hm-2 to 225 kg.hm-2. |
