微喷灌是通过管道用一定的压力,将水以细小的水滴喷到农作物叶面和作物根区地面上的一种精细浇灌、科学用水的新技术。灵川县2008年起实施广西区农业厅蔬菜节水灌溉示范项目。示范应用结果表明,蔬菜香葱生产中微喷灌比传统灌溉可提高产量3.5%,每公顷菜园生产一茬蔬菜可节省浇灌人工27个以上、节省费用1620元,节水600m~3,经济效益、生态效益、社会效益显著。 Micro-sprinkler irrigation through the pipeline with a certain pressure, the water droplets with small droplets of water sprayed onto crop foliage and crop roots on the ground a fine water, science and technology of new water. Lingchuan County in 2008 from the implementation of Guangxi Agriculture Department vegetable water-saving irrigation demonstration project. The demonstration application results show that the micro-irrigation in vegetable chives production can increase the yield by 3.5% compared with the traditional irrigation. The vegetable production in one vegetable garden per hectare can save more than 27 irrigation water, save 1620 yuan, saving 600m ~ 3, Ecological benefits, social benefits significantly.
