Reconstruction of the closed horizontal drains in the Jizzakh region

The use of water-saving irrigation technologies and technical means for irrigating agricultural crops and cotton is one of the leading in the world.”Given the global production of 119.3 million tons of cotton,”† requires the introduction of irrigation technologies that will reduce water consumption and waste in the irrigation of cotton.In this regard, the widespread use of water-saving drip, irrigation, subsoil irrigation methods and discrete irrigation technologies is important in irrigating cotton.

“…For this purpose, observation wells consisting of a three-section perforated pipe with a diameter of 0.05 m and a length of 15 m were used. [3][4][5][6][7].…”

“…The research process was conducted on the basis of generally accepted methods: observation in research, Measurements and analysis Methods in the manuals "Methods of conducting field experiments" adopted at PSUEAITI In determining the representativeness of the field experiment, the methods of V. V. Shabanov and E. P. Rudachenko and software analysis " Determination of changes in soil moisture before and after irrigation based on the use of interpolymer complexes in cotton irrigation" were used [5,6].…”

2023

Research is being conducted around the world to develop technologies for saving and efficient use of irrigation water in the irrigation of agricultural crops. In this regard, special attention is paid to the efficient use of irrigation water, improvement of irrigation techniques and technologies, introduction of modern methods of irrigation, reduction of infiltration and filtration processes in irrigation of cotton, development of methods to retain more soil moisture and justification of irrigation regimes. Nowadays, some results have been achieved based on the research conducted by the above scientists, but insufficient research has been conducted on the effectiveness of discrete irrigation technology for cotton in screen fields formed by interpolymer complexes in typical gray soils of Tashkent region. and methods have been developed to reduce inefficient consumption of mineral fertilizers.

“…Then, considering the water flow time, information was obtained according to the method described in the lower hydropost [1,2,6,14,15]. The absolute water consumption index (S) is determined by the following formula:…”

The country's water supply depends mainly on the water resources of the Amudarya and Syrdarya. 80,7 % of the country's water resources are formed in the Kyrgyz Republic and Tajikistan territory. The population of Central Asia is expected to increase by 40 % in the next 20 years. This, in turn, requires more economical use of water and land resources. At present, it is important to modernize irrigation systems, increase their efficiency, automate water distribution processes, and improve the distribution of water to consumers by accurate measurement of internal channels.
