| 摘 要： | 滴灌供水比是滴灌系统一个重要的设计参数。其取值的大小直接影响工程的投资和运行费用,也影响作物的供水状况,最终影响工程的效益。设计滴灌供水比对滴灌费用的影响一般主要表现于对田间管网费用的影响。该文通过对单位面积支、毛管PE塑料管材用量和田间管网年费用与设计滴灌供水比关系的分析估计设计滴灌供水比对滴灌费用的影响,为合理选择设计滴灌供水比提供依据和参考。

| Abstract: | Designed water application ratio is an important parameter which influences the investment and cost of the drip irrigation system, the water supply situation of crop and finally the benifits of the system. Generally, designed water application ratio has influence mainly on the field pipe network of the system. The influence of water application ratio on the cost of the drip irrigation system is evaluated by analysis of the relationship between the water application ratio and the quantity of the lateral and the submain pipes (PE) , as well as the annual cost of the field network. This can be a reference for the selection of the designed water application ratio. |
