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.
