One of frontiers in agricultural and environmental biotechnology for the arid regions: Micro-pressure drip irrigation technology theory and practices

Abstract

With the goal of reducing cost and energy consumption of drip irrigation systems, the relationship between pressure 
and cost of drip irrigation systems, as well as the feasibility of reducing the operating pressure, were analyzed. The 
irrigation quality and reliability of micro-pressure drip irrigation systems were also studied. A theory of micro
pressure drip irrigation technology is proposed, and the components of this type of irrigation system are presented. 
The results indicate that micro-pressure drip irrigation technology is feasible and that it can significantly decrease 
initial drip irrigation system cost and recurring operating expenses. Micro-pressure drip irrigation can also overcome 
some of the clogging problems of conventional drip irrigation systems. It is suggested that micro-pressure drip 
irrigation will be a topic of importance in the future of agriculture and environmental biotechnology.
