摘要
为有效解决节水灌溉中存在的灌水时间长、能耗过多、灌溉水温低等问题,提出了蓄流分离式灌溉技术理论,基于供水与灌溉不连续、不同步、相互独立的用水机制,将作物灌溉的需用水量通过供、输水方式输至田间蓄流灌水容器之中,作物灌溉用水在自重作用下自流灌溉,即一种供水“蓄”与作物自流灌溉的“流” 之间彻底分离的灌溉方法.通过该技术在果树等稀植经济作物灌溉中的应用表明,该技术与常规灌溉（沟畦灌）相比,节水30%～50%,果树增产5%～20%;与高效节水灌溉技术相比,节能降耗75%以上,用水时间减少50%以上;与常规灌（沟畦灌） 和高效节水灌溉技术相比,提升灌溉水温10%～35%.
There are some problems in efficient irrigation such as long irrigation duration, high energy consumption and low temperature of irrigation water. Hence the author put forward the theory of storage?flow departure irrigation to solve the problems mentioned above. Based on the principles of discontinuous, asynchronous and inter?independent between water supply and irrigation, the irrigation water was shipped to a container used for storing water. The water would flow into the field by gravity. The irrigation system separated the storage process from the water flowing process completely. The storage container irrigation technology had been used in fruits field. Compared with furrow irrigation, this irrigation system could save 30%?50% water, meanwhile got 50% increase of fruits yield;compared with efficient irrigation, 75% energy consumption could be saved and 50% irrigation duration decreased. Compared with both furrow and efficient irrigation system, the storage container irrigation system could increase the water temperature by 10%?35%. This new irrigation technology is effective for saving energy and water, increasing yields and water temperature and alleviating the contradiction of water supply during irrigation season. It can be widely disseminated for sparse planting crops such as fruits.
