摘要
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。
Greenhouse vegetable plantation is selected as an example.According to local hydrogeological characteristics,water source conditions,greenhouse distribution and vegetable planting structure,the design standard parameters such as the overall distribution of the drip irrigation system,the uniformity of irrigation,the allowed irrigation intensity,the designed wetting ratio,the choice of the irrigator,and the limit length of the capillary were calculated and checked in detail.Through the formulation of the irrigation system,the pipe diameter and head loss at all levels of the pipeline were calculated,the filters were selected,the pump model was determined,and the overall design of the drip irrigation system was completed.This drip irrigation design case analysis process is detailed and the results are reasonable,which can be used as a reference for related drip irrigation project design.
