摘　　要：介绍了一种经济实用型机械注入式施肥装置,该施肥装置采用耐腐蚀泵将肥料原液强行注入灌溉管网并与灌溉水进行混合从而获得一定浓度的灌溉液。灌溉液浓度通过标有流量示值的手动流量调节阀进行调节,从而实现节水灌溉微滴灌系统灌溉过程的比例施肥控制。灌溉液浓度控制准确度明显高于文丘式和压差式，可用于滴灌系统的准确经济施肥。This paper introduces a new type of mechanical injecting fertigation device, which injects liquid fertilizer into irrigation pipe net by corrosion-resistant pump and brings the blend of irrigation liquid. The concentration of irrigation liquid is regulated by manual flux adjusting valve in order to fulfill the proportion fertilizing of water-saving micro-irrigation & drip irrigation system. With much higher control precision than the Venture device and the pressure differential device, the mechanical injecting device can be applied to the precision and economical fertigation of water saving drip irrigation system.
