摘要
施肥灌溉是灌溉设施的主要功能之一 本文创新地研制了水动施肥装置 ,它利用施肥主管高压水自身的压力 ,推动泵缸活塞来回运动而把肥液注入到主管中去 作者通过对该装置的设计、研制和试验 ,分析注肥流量和注肥频率 ,得出所研制的水动施肥装置运行成本低、适用性好 ,特别适合于小规模。
Fertilization is one of the main functions of the irrigation system. The authors develop a hydrodynamic fertilizer injection unit in which the high force of water in the main tube is utilized to push the piston to run back and forth to inject the fertilizer into the main tube .The authors analyze the rate of the flow and the frequency of fertilizer injection on the basis of the design, research and experiment ation of the unit, and reach a conclusion that the hydrodynamic fertilizer injection unit ia lover in cost, better in adaptability and extremely suitable for small scale fertilization equipment.
