低压条件下蓄水灌灌水均匀度实验分析
Experimental Analysis of Irrigation Uniformity of Storing Irrigation Based on the Low- head Irrigation
摘要
Abstract
[ Objective ] The purpose of the project aims to research and analyze the influence of capillary length and diameter, water supply pressure, water storage time, different specifications of microtubule capillary affecting irrigation homogeneous degrees. [Method] Through different emitter flow observation tests under low single supply capillaryt, values of emitter water flow and irrigation uniformity of storing irrigation by different water supply pipe length and diameter were got, and different water volumes under pressure were analyzed. [Result] When other influencing factors are of equal conditions, irrigation evenness increases with water supply capillary length reduced and with the pipe diameter increased; Irrigation evenness also increases with water supply time extended; The 3. 5 m length of the end tube with 4 mm diameter is the most reasonable. [ Conclusion] When supply pressure varies within the range of 30 to 60 cm, water supply pressure has no big effect on the irrigation and the irrigation can meet all the homogeneous degree above 0. 9. This suggests that storage irrigation methods to solve and tackle the poor uniformity of natural low head micro spray irrigation systems are an effective technical approach.关键词
