A farmland irrigation and drainage system includes: a water inlet pool, the water inlet pool being provided in a piece of farmland, and the water inlet pool being made with a water-filtering material; and, a water outlet pool, the water outlet pool being provided at an interval to the water inlet pool in the farmland, a water overflow being provided on the sidewall of the water outlet pool The water outlet pool is communication with the farmland via the water overflow, and a predetermined water level of the farmland is controlled by controlling the height of the water overflow. The technical solution of the present application solves the problem that automatic irrigation and drainage could not be implemented by a farmland irrigation and drainage system in prior approaches.

An emitter outlet defining an ingress channel having a first volume and area, and having a first portion that is substantially perpendicular to a second portion located downstream of the first portion which causes fluid flowing through the ingress channel to make a first fluid velocity reducing turn, and a first opening located off of the second portion that causes at least a portion of the fluid flowing through the ingress channel to make a second fluid velocity reducing turn, and an outlet bath with a second volume and area that is larger than the first volume and area of the ingress channel so as to cause further pressure and/or velocity reduction of the fluid entering into the outlet bath. In addition, emitters, drip lines and various methods relating to such an emitter outlet configuration are also disclosed.

An irrigation system having a reservoir with self-sealing openings is provided. The reservoir may comprise a body having an outer surface and a cavity for storing fluid. The reservoir may also include a plurality of self-sealing openings on the outer surface and configured to move between a first configuration in which the self-sealing openings are closed and a second configuration in which the self-sealing openings are open and permit fluid to release from the cavity to a target zone. The self-sealing openings are in the first configuration when a fluid pressure in the reservoir is at least one of zero pressure or negative pressure and the self-sealing openings are in the second configuration when the fluid pressure in the reservoir is a positive pressure relative to an external pressure.
