摘　　要：微润灌溉将半透膜技术原理引入灌溉领域,其以微量缓慢但连续不断的出水形式向土壤供水,微润管既是输水管又是给水器,管上的每一处都是出水点,因此对这种特殊沿程泄流管道的水力性能的研究具有重大的意义。本文根据试验所得数据进行微润管水力计算,并尝试性地优化微润灌溉的水力计算基本公式及其他相关设计原则。实验分析表明微润灌可保证作物正常生长的适宜水分,同时也明显地提高了节水灌溉水平。研究结果可为微润灌溉技术提供最基础性的理论依据。Micro-moist irrigation combined with semi-permeable membrane technology,it permeated the soil in the form of slow trace but continuously.Moistube is a water pipe,as well as a supply device,on which every point is an emitter.Therefore,it is significant to study the hydraulic performance along the unique sluicing pipe.In this paper,it conducts hydraulic computation of the moistube based on the experimental data,and attempts to optimize the hydraulic computation formulas and other related design principles.Experiments show that the moistube can ensure the suitable water for growth of most crops,meanwhile significantly improve the irrigation level.The research results can provide a theoretical basis for the micro-irrigation technology.
