田间喷-管结合灌水技术体系的研究

该文在总结以往经验基础上，分析了喷灌与管灌在粮田灌溉中的优点和缺点，针对北方地区管灌面积甚广，亟待配套完善的现状，提出了“喷－管结合，扬长避短，择优施灌”的田间灌水新技术体系，通过配套部件研制、测试及田间对比试验和投资、能耗分析，这一体系在技术上是可行的，经济上是合理的。并已在北京等地推广应用。

Study on Sprinkler Pipe Conveying Irrigation System in Field

The advantages and disadvantages of sprinkler irrigation and pipe conveying irrigation were discussed. Considering the pipe conveying irrigation is used in most of the area under cultivation in north China and the irrigation system needed to be perfected, a new type of irrigation system named sprinkler pipe conveying irrigation was developed. This system combines the advantages of sprinkler irrigation and pipe conveying irrigation together. And it carries out the sprinkler part in the initial crop growing peroid, the pipe part running in the final crop growing peroid. the experimental test and the economic analysis reults showed that the new irrigation system is reasonable and feasible in the aspects of technique and economy. The new irrigation system has been extended in several regions and provinces such as Beijng, Heibei and Liaoning.
