半固定式喷灌是一种较成熟且适用的高效节水灌溉技术,与传统地面灌溉相比,可以有效减少输水渗漏,提高输水效率,一般不会产生径流和深层渗漏,田间水利用系数高,容易实现自动化,节省劳力,适应性强,且半固定式喷灌系统支管可重复使用,能降低投资,操作方便,占地少。文章以蔬菜地半固定式喷灌高效节水灌溉工程为例,对半固定式喷灌工程设计方案的各环节进行了详细论述和分析,对类似工程设计具有一定的借鉴和参考作用。
Semi-stationary sprinkler irrigation is a more mature and applicable high-efficiency water-saving irrigation technology, compared with the traditional surface irrigation, which can effectively reduce water leakage and improve water transmission efficiency, generally does not produce runoff and deep leakage, field water High utilization factor, easy to automate, labor-saving, adaptable, and semi-fixed sprinkler system branch pipe can be reused, can reduce investment, easy operation, small footprint. Taking vegetable semi - fixed high efficient water - saving irrigation project as an example, the article discusses and analyzes all aspects of semi - fixed sprinkler irrigation project design scheme in detail, and has some reference and reference for similar project design.
