本项试验采用先进的渗灌理论，利用当地生产的再生塑料管，为山坡地枣园精心设计了一套成本低、施工简便、易于黄土高原地区使用的渗灌系统。结果表明；根系分布层直接渗灌技术，不仅其节水效果显著，而且可以改善土壤的理化性能，减少地表水分蒸发损失，增加土壤含水量，减轻病虫的危害，提高枣树生长量，促进枣树早挂果。 This experiment uses advanced seepage irrigation theory, using the local production of recycled plastic pipe, for the hillside Jujube Park carefully designed a low cost, easy construction, easy to use in the Loess Plateau irrigation system. The results showed that the direct seepage irrigation technology of root distribution layer could not only improve the water saving effect, but also improve the physical and chemical properties of soil, reduce the loss of surface water evaporation, increase the soil water content, reduce the harm of pests and diseases, increase the growth of jujube trees, Jujube early fruit hanging.
