在山西省稷山县棉花、葡萄及日光温室蔬菜上的试验、示范结果表明,滴灌施肥具有显著的"两节"、"两增"功效。两节指节水:与大水漫灌相比,节水813~2 685 t/hm2,节省投资408.8~1 342.5元/hm2,水分利用率提高36.5%~43.5%;节肥:与常规施肥相比,节肥90~225 kg/hm2(纯养分),节省投资420~1 800元/hm2,肥料利用率提高15.2~24.2个百分点。两增为增产:与常规田相比,每公顷增产棉花8.26%、葡萄22.22%、日光温室蔬菜3.76%;增效:与常规田相比,棉花、葡萄、日光温室蔬菜增加纯收益分别为1 992,19 227和19 797元/hm2左右。
