摘 要:为保障水资源平衡,缓解旱情,分析了公主岭市某村改造的1万亩中低产田,根据当地地下水承载能力,充分开发利用地下水资源,建设了水源井工程、首部工程及地下铺设干管,地面铺设支管、毛管的滴灌系统工程。通过对项目区的水资源供需平衡分析,应用膜下滴灌节水灌溉技术,大幅度降低了农业灌溉用水,使地下水不再过度开采。经过几年的运行及实践,万亩中低产田改造项目起到了玉米膜下滴灌的示范性作用,使地下水资源系统和地表植被系统恢复了原有平衡。In order to guarantee water resource balance and remit damage to crops by drought,the research analyzes the 1 million mu of medium and low yield field in a village in Gongzhuling City.According to underground water carrying capacity,the city fully develop and utilize groundwater resources,and constructs trickle irrigation systems engineering of water source well,prelude and underground main pipe,ground branch and hollow pipe.Through the analysis of water resource co-ordination of supply and demand of the project areas,water-saving irrigation technique of drip irrigation under plastic film is applied to largely reduce agricultural irrigation water,and avoid the over-exploitation of underground water.After years of operation and practice,1 million mu of medium and low-yield field renovation project have played the model function of corn drip irrigation under plastic film.In this way,underground water resource system and ground vegetation system have recovered original balance.
