摘要
研究了旱塬区5种地下微灌补水系统对棉花产量和水分生产效率的影响。3年试验结果表明,5种地下微灌补水系统均可提高棉花产量和水分生产效率,其中微灌补水系统1效果最好,其棉花产量和水分生产效率比传统旱作分别可提高35.6%～55.1%和26.9%～46.7%,新增投资收益率高、回收期短。
The experiments were conducted to evaluate the effects of 5 different underground filtration irrigation systems to cotton yield and water use efficiency in semi-arid region from 2003 to 2005. The results showed 5 different underground filtration irrigation systems significantly increased cotton yield and water use efficiency. Underground filtration irrigation system No. 1 was the best irrigation system, it increased cotton yield by 35.6% - 55.1% and improved water use etticiency by 26.9% - 46.7% compred with traditional cultivation. It suggests underground filtration irrigation system No.1 is the best irrigation system in semi-arid region for cotton.
