山坡地枣园低压渗灌系统试验研究初报
- Title:
- The Preliminary Study on Low-stress Seep Irrigation System in Slope Land
- Keywords:
- slope land; jujube orchard; saving water irrigation
- 摘要:
- 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.
- Abstract:
- Adopting advance seep irrigation theory,using local regenerating plastic pipe,a set of seep irrigation system with such advantages of low cost,simple operation,and easily using in Loess Plateau,were designed in slope land.The research results suggested the direct irrigationin root distribution layer not only might save water,but also might improve soil chemical and physical properties,reducing evaporation loss of ground water,increase soil water content,alleviate the harm of plant diseases and insect pests,increase the growth amount of Chinese jujube,and accelerate early fructification.
