【摘要】 随着全球水资源的日益短缺,节水灌溉越来越引起人们的重视。地下滴灌是一种节水效率很高的节水灌溉技术,具有诸多优点。本文分析了地下滴灌毛管埋深和间距对作物生长和发育的影响,重点介绍了国内外地下滴灌毛管埋深和间距的研究进展及应用现状,对其发展历史、经济与环境效益、毛管埋深、毛管间距、作物的生长和发育及系统的投资等方面进行了综述,并对毛管埋深5 cm、15 cm和35 cm进行了土壤水分运移试验分析,以便为地下滴灌系统的合理设计提供理论依据。更多还原

【Abstract】 People pay more attention to the water saving irrigation as the water resources in the world become shorter and shorter.Subsurface drip irrigation is a high efficient irrigation technology which has many advantages.The effects of depth and interval of lateral pipes to crop growth and development have been analyzed,major introduced the researth progress and application situation of the depth and interval of lateral pipes at home and abroad,included the history of development,the economic and environmental benefits so on,carried out the soil-water movement analysis for the depth of lateral pipes at 5cm,15cm and 35cm in order to supply the theory basis for the resonable design of the subsurface drip irrigation system.更多还原
