白沙灌区现有的灌溉模式主要有续灌和轮灌两种。因不同的干渠所控制灌溉面积不同、土质不同、旱情出现的时间不同、水费收缴的难易程度不同,所以各个干渠应根据各自的特点选择适合自己的灌溉模式。这样既能节约水资源,又能充分发挥各个干渠的最大作用。 The existing irrigation patterns in Baisha irrigation area are mainly two types of continuous irrigation and rotary irrigation. Because different irrigation canals control different irrigated areas, different soil types, different times of drought appeared, and the difficulty of collecting water fees is different, so each canal should be selected according to their own characteristics for their own irrigation mode. This will not only save water resources, but also give full play to the greatest role of all the major channels.
