多种经济作物的高效节水灌区流量规模分析

Flow analysis for efficient water-saving irrigation zone with multi kinds of economic crops

高效节水灌区内有多种经济作物且不同作物的灌水时间有可能重合时,为节省规模,需要考虑绘制灌水率图、分析灌水率过程量、流量循时叠加等问题。通过对比传统的渠道输水灌区、种植结构单一的高效节水灌区等其他类型的灌区,以百色灌区为例,分析多种经济作物的高效节水灌区的流量规模。

For an efficient water-saving irrigation zone with multi kinds of economic crops,different crops may re-quire irrigation at the same time. In order to reduce flow scale,it is necessary to draw irrigation rate curve,analyzechange process of irrigation rate and flow circulation superposition. Comparison was made with other kinds of irriga-tion zones such as traditional channel irrigation zone and efficient water-saving irrigation zone with single plantingstructure. Taking Baise irrigation zone as example,the author analyzed the flow scale of efficient water-saving irri-gation zone with multi kinds of economic crops.
