摘要
抓住影响滴灌系统造价的主要管材费用、电费两项因素,通过年值法试算系统费用,获得经济管径,为精确确定微灌系统经济管径的选取提供可行的方法。
Surrounding two main factors of pipe and electricity cost of drip irrigation systems,this paper achieved economic pipe diameter by the test of annual cost method,aimed to provide viable means for the selection of micro-irrigation system.
