| 摘 要： | 采用田测法对三江平原控制灌溉下稻田灌溉水量、耗水量、产量和水分利用效率进行了研究。实验采用控制灌溉Ⅰ、控制灌溉Ⅱ和淹灌3种灌水处理。结果表明：控Ⅰ灌、控Ⅱ灌和淹灌3种处理的总灌溉水量分别为344.1mm、319.4mm和467.4mm,与淹灌处理相比,控Ⅰ灌和控Ⅱ灌处理分别节省灌水26.4%和31.7%。在整个生育期内田测法测得的控Ⅰ灌、控Ⅱ灌和淹灌3种处理的耗水量分别为538.5mm、500.5mm和627.8mm,与淹灌处理相比,控Ⅰ灌和控Ⅱ灌处理分别节水14.2%和20.3%。控Ⅰ灌、控Ⅱ灌和淹灌3种处理的实际籽实产量分别为10 200 kg·hm^-2、10 500 kg·hm^-2和9 320kg·hm^-2,控Ⅰ灌和控Ⅱ灌处理分别增产9.4%和12.7%。控Ⅰ灌、控Ⅱ灌和淹灌3种处理的水分利用效率分别为1.89kg·hm^-3、2.10 kg·hm^-3和1.49 kg·hm^-3,控Ⅰ灌、控Ⅱ灌的WUE分别较淹灌增加26.9%和40.9%。对比分析结果表明,控制灌溉在节约水资源的同时还能提高产量,控Ⅱ灌的节水和增产效果都略优于控Ⅰ灌。图3,表4,参7。 |

| Abstract: | Field experiment with three irrigation treatments,i.e.,control irrigation I,control irrigation II and continuous flooding irrigation were installed to study the irrigation water,water requirement,yield and water use efficiency(WUE) of rice of Sanjiang Plain under different irrigation treatment.The results showed that the total irrigation water was 344.1,319.4 and 467.4mm for control irrigation I,control irrigation II and continuous flooding irrigation.The total irrigation water of control irrigation I and control irrigation II were lower than that of continuous flooding irrigation by 26.4% and 31.7%.In field experiment,the total water consumption was 538.5,500.5 and 627.8mm for control irrigation I,control irrigation II and continuous flooding irrigation,respectively during the entire growing season.The total water consumption of control irrigation I and control irrigation II were lower than that of continuous flooding irrigation by 14.2% and 20.3%.The yield of control irrigation I,control irrigation II and continuous flooding irrigation was respectively 10200,10500 and 9320kg·hm-2.The yield of control irrigation I and control irrigation II were 9.4% and 12.7% higher than that of continuous flooding irrigation.The WUE of control irrigation I,control irrigation II and continuous flooding irrigation was respectively1.89,2.10and 1.49kg·m-3.The WUE of control irrigation I and control irrigation II were higher than that of continuous flooding irrigation by 26.9% and 40.9%.The results showed that control Irrigation was a comparatively water-saving and yield-increasing irrigation treatment.Water conservation and yield increase of control irrigation II were better than those of control irrigation I. |
