- 摘要:
- 黑龙江蛤蟆通灌区运行多年,为了适应种植业调整和调高灌溉水利用率,进行大规模节水工程改造。结果表明:通过渠道建设、维修建筑物、工程管理等措施,渠系水利用系数由0.59提高到0.63。灌区毛灌溉定额由10 305 m3?hm-2减少到7 575 m3?hm-2。调整水旱田灌溉面积比例,增加水田面积0.221万hm2,提高粮食产量。
- Abstract:
- Hamatong irrigation district of Heilongjiang has been running for many years.In order to adapt to the planting industry and adjust the irrigation water use efficiency,the reform of large scale water saving projects was carried out in this region through the channel construction,maintenance buildings,engineering management and other measures.The coefficient of irrigation water use increased from 0.59 to 0.63.Irrigation quota by 10 305 m3?hm-2?meters reduced to 7 575 m3?hm-2.The above measures adjusted the area ratio of paddy field and dry farmland irrigation,increased 2 210 hm2?of paddy field area and grain output.
