大棚蔬菜滴灌系统案例设计与分析

选取大棚蔬菜种植园为实例,根据当地的水文地质特征、水源条件、大棚分布以及蔬菜种植结构,详细计算并校核了滴灌系统的总体分布、灌溉均匀度、允许灌溉强度、设计湿润比、灌水器选择、毛管极限长度等设计标准参数。通过灌溉制度的制定,计算各级管道管径、水头损失,选择过滤器,确定水泵型号,完成了滴灌系统的整体设计。该滴灌设计案例分析过程详细,结果合理,可作为相关滴灌工程设计参考依据。

Design and Analysls on Drip Irrigation System for Greenhouse Vegetables

s: Taking the greenhouse vegetable plantation as an example, According to the local hydrogeological characteristics, water source conditions, greenhouse distribution and vegetable planting structure, the design standard parameters such as the overall distribution, irrigation uniformity, allowable irrigation intensity, design wetting ratio, emitter selection and capillary limit length of drip irrigation system are calculated and checked in detail. Through the establishment of irrigation system, calculation of pipe diameter and head loss at all levels, selecting the filter, determining the type of the pump, complete the overall design of drip irrigation system. The case analysis process of drip irrigation design is detailed and the results are reasonable, which can be used as reference for relevant drip irrigation engineering design.
