Abstract

Watering technology is a method of water supply for plants under the form of artificial rain using water-jets. Watering systems can fully satisfy water supply requirement for trees, supporting the ground and highly mechanization watering activities. From theoretical and experimental point of view, this article shows that water-jets with 1st spraying angle θ1 = 64° and 2nd spraying angle θ2 = 45° will satisfy agricultural technical requirement in the best, giving highest productivity, lowest cost or biggest economical efficiency.
