日光温室管网化灌溉自动施肥系统的研究与设计

The Research and Design on the Automatic Topdressing System for Pipe Network Irrigation in Sunbeam Greenhouse

依据流体动力学原理，利用日光温室管网灌溉的静压能和文丘里管的特性，设计出在日光温室进行正常灌溉的情况下，实现施肥自动化的日光温室管网化灌溉自动施肥系统。该系统可操作性强，能大幅度减轻劳动强度，提高工作效率；适合于中等生产水平的日光温室蔬菜生产区。

This design is based on the principle of hydrokinetics,the energy of static pressure for pipe network irrigation in sunbeam greenhouse and the feature of Venturi Pipe,which can realize the topdressing automation in vegetable production period under normal irrigation conditions in sunbeam greenhouse,and can alleviate the intensity of labor and increase work efficiency.This design is operational and suitable for middle-level vegetable production areas where greenhouses are used.
