Purpose: to develop a design-layout scheme for a two-line irrigation module of a drip irrigation system, providing effective drip irrigation of perennial tree fruit crops cultivated in garden plantings.
Materials and methods. The main requirements for developing an irrigation module scheme are: ensuring the required proportion of moisture area, ensuring a regulated distance between the woody plant stem and the nearest emitter at least 0.2 m, ensuring the possibility of periodically changing the emitter position relative to the plant stem. When developing the scheme of the irrigation module, the methods of search design were used.
Results. A constructive scheme of a two-line irrigation module intended for drip irrigation of one row of plants in a perennial tree fruit plantation is proposed, it includes two irrigation lines symmetrically located relative to the axis of a row of plants with emitters arranged in them. Drip tubing with wall thickness from 0.8 to 1.2 mm is recommended for use as irrigation lines. Drip lines are located on supports at a height of 50 cm from the earth's surface and have the ability to change their position relative to the axis of a row of plants. The head and tail structure of the irrigation module are connected to the supply and discharge pipelines through flexible water conduits. The end part of the irrigation module provides for the possibility of collecting and discharging wash water (solution).
Conclusions. As a result of the studies carried out, a constructive solution for a two-line irrigation module of a drip irrigation network was proposed, which allows: to increase the proportion of the moistening area from the area of nutrition of each plant to the standard values, to ensure effective watering of the root-inhabited soil space at different stages of plant growth and development, to reduce the intensity of soil degradation during drip irrigation.
