Abstract
Recently, the Government of the Republic of Azerbaijan has been paying considerable attention to the development of one of the main factors in the intensification of agriculture, irrigation reclamation.
The long-term program for its development provides as an extension of the state of existing irrigation systems. One of the promising areas in Azerbaijan for the cultivation of vegetables, fruits, etc. is the Guba-Khachmas zone, where in recent years numerous specialized farming and individual farms for the production of fruits and vegetables have been organized.
At present, in the Guba-Khachmas region, irrigation using the furrow method and in places with built-in stationary pulsed sprinkler devices of self-oscillating action (SIMDAD) from a closed network is used in the Guba-Khachmas zone for irrigation of vegetables and fruit trees.
The use of irrigation methods existing in this region (furrow irrigation and or conventional irrigation) under the conditions under consideration often leads to soil erosion.
One of the ways to increase the efficiency of stationary sprinkler systems on steep slopes is the introduction of technology and technical means of low-intensity irrigation, which could reduce construction costs and completely eliminate soil erosion.
For this purpose, it is necessary to apply appropriate ecologically acceptable equipment, which should provide the following multi-intensive long-term impact on the plant, soil and surface air layer by reducing the intensity of water supply (I) and bringing its value closer to the intensity of water consumption (E).
And ≤ (İ-100) E; (1)
To the foregoing, synchronous sprinkling is most suitable.
Pulse sprinkling systems operate in a semi-automatic mode and during continuous operation the daily water supply is 96 m3 / ha, which is almost three times higher than the average daily water consumption rate of an agricultural field in this zone.
