1. The capillary in micro-irrigation system and micro-pressure porous hose in this paper are long porous hoses. The influences caused by some factors such as the laying of the hose, the imported pressure head, the diameter of hose and drop-distance on uniformity and head of the deviation are discussed. There is an optimum laying of the slope on the premise of the allowed flow deviation rate of the hose is pointed out. The situation of project application about micro-pressure hose irrigation technology is introduced, and calculating method on how to determine the laying of a reasonable length of hose is referred, and the appropriate laying length that meets required uniformity is given.
