武威水资源人均735m3,是全国的1/3,全省的2/3。低于酒泉人均7600m3和张掖3020m3。近年来,由于农作物种植结构调整,间作套复种面积扩大,城市工业用水增加,农业用水矛盾更加突出。通过对缺水原因的分析,提出了以工程措施和农艺措施并重,减少灌溉用水,提高水分利用率,实现水资源高效利用的节水农业发展思路。
Wuwei water resources per capita 735m3, is 1/3 of the country, 2/3 of the province. Lower than 7600m3 per capita in Jiuquan and 3020m3 in Zhangye. In recent years, due to the adjustment of crop planting structure, the intercropping of multiple cropping and the expansion of industrial water use in urban areas, the contradiction between agricultural water use has become even more prominent. Based on the analysis of water shortage reasons, the paper puts forward some ideas of water-saving agriculture which takes both engineering measures and agronomic measures into consideration, reduces irrigation water, improves water use efficiency and makes efficient use of water resources.
