蔬菜生产在密云县已经成为促进农民增收致富和农村经济发展的主导产业。因此研究资源型缺水地区大棚蔬菜采取非充分灌溉条件下的节水高产高效的灌溉制度和相关技术措施,通过减少颗间蒸发及作物蒸腾,降低棚内湿度,减少病虫害,提高产品质量和产量,增加农民收入。这样有利于指导今后的蔬菜灌溉,达到节约农业用水和增产、增效、降低ET值的目的。
Vegetable production in Miyun County has become the leading industry for promoting peasants’ income growth and rural economic development. Therefore, the research on water-saving, high-yield and high-efficiency irrigation system and related technical measures under greenhouse irrigation in resource-intensive and water-deficient areas can reduce the greenhouse humidity, reduce pests and diseases, improve product quality and yield by reducing inter-evaporation and crop transpiration , Increase peasant income. This will help guide the future of vegetable irrigation, to save water and agricultural production and increase efficiency, reduce ET value purposes.
