摘　　要：针对某蔬菜基地供水保障项目实例,提出计算项目灌溉规模和实际需求量的重要意义,提高水资源利用效率、推动当地农业经济稳步发展等,通过合理确定灌溉规模、详细计算灌溉需水与灌溉用水量,有效分析不同种植结构的实际用水量,种植2季(“白菜-甜椒”组合,若灌区水源匮乏,可采用“辣椒-白菜-3”的组合),80%保证年灌溉定额为1 500 m^(3)/hm^(2),保证率80%的月最大用水为450 m^(3)/hm^(2)即15.00 m^(3)/(hm^(2)·d),此种种植模式较为经济。Based on the example of a water supply guarantee project of a vegetable base, the significance of calculating the irrigation scale and actual demand of the project is put forward, so as to improve the utilization efficiency of water resources and promote the steady development of local agricultural economy, etc. By reasonabe determination the irrigation scale, detailed calculation of irrigation water demand and irrigation water consumption, effective analysis of the actual water consumption of different planting structures and planting two-season mode, which refers to the combination of cabbage and sweet pepper(if the irrigation area is short of water, the combination of pepper-cabbage-3 can be adopted), the 80% guaranteed annual irrigation quota is 1500 m^(3)/hm^(2),and the monthly maximum water consumption of 80% is 450 m^(3)/hm^(2) that is, 15.00 m^(3)/(hm^(2)·day). This planting mode is relatively economical.
