渭北旱塬膜上灌灌水技术试验研究
- Title:
- Study on Irrigating Technique of Film Hole Irrigation in Weibei Dry Plateau
- 摘要:
- 膜上灌是起源于我国新疆的节水灌溉新技术,因水在膜上流动,流动速度快,减小了水分深层渗漏,同时水流由渗水孔和放苗孔渗入土壤和作物根系周围,因而提高了灌水均匀度和灌溉水的利用效率,具有很大的节水潜力.着重从水流运动特性、渗水孔面积、膜畦长度、生长和产量状况、水分利用等方面介绍了膜上灌技术在渭北旱塬研究的初步结论.
- Abstract:
- Film hole irrigation which produces in Xinjiang is one new water saving irrigation method.Because of water flowing on film and infiltration into the soil through the hole and distributing around the roots of corp,this method decreases the water deep loss and increases the irrigation regularity and utilization efficiency,and has very high potentiality of water saving.The research results of film hole irrigation in Weibei dry plateau are introduced through the property of water movement,area of infiltrating hole,length of film,growth and yeild,water utilization.
