| 摘 要： | 将现有非充分灌溉技术研究成果应用于大田作物中,从作物耗水量、单产、产量要素、水分生产率、节水量与总效益等方面进行了综合评价。结果表明,与充分灌溉相比,非充分灌溉(Ⅰ)节水增效显著,非充分灌溉(Ⅱ)总产量或总效益下降较大,实际应用中应把握好非充分灌溉度的问题。 |
| 关 键 词： | 大田作物 非充分灌溉 效果 评价 |

| Abstract: | Comprehensive evaluation is made on crop consumptive use,specific yield,factor for output,water productivity,quantity of water saved and total benefit with deficit irrigation technical research results being used in field crop irrigation.The results indicate that in comparison with copious irrigation water saving and benefit increment of deficit irrigation alternative(Ⅰ) is remarkable,while gross output and total benefit of deficit irrigation alternative(Ⅱ) decreases significantly,therefore deficit irrigation should be implemented according to specific condition. |
| Keywords: | field crop deficit irrigation result evaluation |
