Abstract: A micro-irrigation system includes at least one stake, tubing section, and micro-spray jet. The stake has a lower end configured for retention at a junction of four corners of adjacent planting pots and an upper end having a tubing retention prong and a micro-spray jet retention opening with an internal fluid passage extending therebetween. The tubing section is connected to the tubing retention prong and adapted for connection to a water supply. The micro-spray jet is connected to the retention opening, an internal fluid passage extends from the lower end to an orifice in an intermediate surface, and a splash plate is located above the jet orifice. The splash plate has a plurality of downwardly extending sides about its periphery with clearances therebetween defining a jet spray pattern. With water supplied through the tubing, at least one spray stream is directed into each of the four adjacent pots.

Abstract: An improved irrigation system for low-volume flow to individual plants or trees is presented. The system involves a detachable irrigation emitter with a flow deflector. In addition, an easily interchangeable dual flow pattern adapter is presented that can be slipped over the irrigation emitter in two different ways, thus providing two different deflection faces to produce two different flow patterns. Thus, with only one adapter, three distinct spray patterns may be selected at each plant site with much less time and labor than in previous systems. In a further embodiment, flow pattern adapters with three and four deflection surfaces are described, offering the choice of four and five distinct spray patterns at each plant site, respectively.
