摘    要:针对有压节水灌溉的高耗能,提出并试验了用无压负压给水器为作物即节水又节能的双节给水理念,针对间歇灌溉时土壤湿度忽高忽低提出连续适度给水理念,给水理念特点是利用植物水分生理水势特性,与土壤张力特性,利用给水器将水分以无压或负压形式与土壤和植物根系连接成负压水分运动系统,与有压节水灌溉对比节省了加压耗能,与灌溉理念差别是变间歇式灌溉为连续向作物供水,供水过程与作物需水过程平行,具有精准给水特点。简介了双节给水的理论基础、方式方法以及负压给水、超微压给水、毛细给水、寝润给水技术的试验研究数据。

关 键 词:作物双节给水  负压给水  超微压给水  毛细给水  庄润给水

Abstract:In view of the pressure of saving water,the shortcoming that the irrigation consumes a large amount of energy,the negative pressure water feeder for the crops,namely,the double festival water-saving and energy saving water concept is proposed.Intermittent irrigation for the soil moisture the concept of continuous moderate water is proposed.Plant-water relations of the water potential characteristics are used.Use is made of water supply machine humidity.Water supply process and farm crops need water process ...
Keywords:double water supply  negative pressure water supply  ultra small pressure water supply  capillary water supply  infiltration water supply
