微灌是根据物需水要求,通过低压管道系统安装在末级管道上的特制灌水器,将水和作物生长需要的养分以较小的流量均匀、准确地直接输送到作物根部附近的土壤表面或土层中的灌水方法。2012年,辽宁省在辽中县六间房镇7个村实施棚菜农业节水示范工程,实施微灌陆地大棚蔬菜灌溉面积0.02万hm2,工程总投资25万元。工程于2012年3月15日开始施工,2012年4月15日竣工,工期1个月,项目经过2a的运行取得良好的效益。基于此,根据大棚蔬菜微灌工程建设实践浅谈蔬菜微灌工程系统的主要4个主要组成部分。
Micro-irrigation is based on physical and water requirements, through the low-pressure pipe system installed in the last pipe on the special emitter, the water and crop growth nutrients required with a smaller flow rate evenly and accurately transported directly to the crop roots near the soil surface Or soil irrigation methods. In 2012, Liaoning province implemented the greenhouse vegetable water saving demonstration project in 7 villages of Liufangfang in Liaozhong County. The area of irrigated vegetables with micro-irrigation land greenhouses was 0.02 million hm2 and the total investment was 250,000 yuan. The project started construction on March 15, 2012 and completed on April 15, 2012, with a construction period of 1 month. The project achieved good benefits after 2 years of operation. Based on this, according to the greenhouse vegetable micro-irrigation project construction practice of vegetable micro-irrigation engineering system of the four main components.
