Research Progress of Micro-sprinkler Belt Irrigation Technology
Micro-sprinkler belts are widely used in agricultural production in recent years because of their advantages of easy installation,anti-clogging and low investment.Compared with sprinkler and drip irrigation,the relevant theoretical re-search of micro-sprinkler is not yet perfect.The theories related to micro-spray belts are summarized from five aspects,namely,the current status of manufacturing of micro spray belts,hydraulic properties,spray uniformity,combination de-sign,and applications.In general,the performance of micro-spray belt products currently on the market is uneven.In the aspect of research,the hydraulic characteristics of micro-sprinkler belts are mostly obtained by experiment,but the means of establishing computer model to simulate is still rare.Due to the characteristics of both sprinkler and drip irrigation,the reasonable design of spray uniformity and related design specifications need to be further studied.In terms of application,intelligent water-fertilizer integration irrigation technology is the future development direction of micro-sprinkler irrigation technology.
