摘要
经多年试验观测,膜上灌可节水20%~30%,增产4%~5%,投资少,方法简单易行,是干旱绿洲灌溉农业区地膜栽培作物节水灌溉的有效途径。文章分析了膜上灌的节水原理、节水效果及对作物根系分布的影响,并提出了其技术规范。
The irrigation on membrane can save 20%~30% of water and increase 4%~5% of crop yield and has the advantages of less investment and easy operating by years experiment and investigation. It is an effective way for water-saving irrigation of ground membrane planting crops in the arid and green sand bar. The water -saving principle, effect and impact to crop roots distribution are analysed and the technology standard is also presented in this paper.
