drainage, 50 thousand km of ditches are being cleaned, 200 km. More than 30 km
of canals, 30 km of trays and 500 km of collector networks, more than 400 hydro-
ameliorative facilities and many other facilities are being reconstructed and
constructed.
In particular, as a result of the state policy on
the rational use of water
resources in Uzbekistan today, the total amount of water used has decreased by
20% compared to the 80s.
If in the 90s, 18,000 m3 / ha was used for 1
hectare of irrigated land, today
this figure is reduced by 40%.
It is known that from this year the privileges on water tax for agricultural
enterprises have been canceled. As the scope of
water-saving technologies
expands, so does the need to develop them. However, the capacity of 13
specialized enterprises in our country is not enough to cover half of next year's
needs.
Another innovation in the industry is that the clusters have managed to reduce
water consumption by 20-25%, fertilizer by 15% and increase productivity by at
least 10% by leveling more than 3,000 hectares of land with the help of lasers.
Another problem with water wastage is that today only 2% of more than
3,000 water metering stations and 2.5% of 400
large water facilities have
automated control systems.
Among the measures for the efficient use of water in the irrigation of crops,
the implementation of a number of organizational aspects directly serves to
increase the efficiency of water use.
In particular, the organization of alternating
water use among farmers, as a
result of which water is transferred first to one field and then to another, reduces
water loss in the canal by 10-20%, and water loss in the upper reaches by 30-35%;
• measures to clear irrigation ditches of mud and weeds, and to repair broken,
cracked and perforated areas of concrete and new ditches
will also improve field
water supply;
• equipping farms with water intake and metering facilities will allow for a
fair distribution of water;
• moisture accumulation irrigation in early spring or before sowing allows
cotton to be harvested evenly without the first irrigation;
• the introduction of strict water accounting will
ensure the targeted and
efficient use of water.
Several types of water-saving technologies are used in our country, including:
1. Irrigation with film on the crop;
2. Use of flexible film pipes instead of pipes;
3. Application of subsoil irrigation technology, field irrigation will be reduced
by 25-30%, no crops will be harvested;
4. Irrigation (mainly annual crops are irrigated).
5. Drip irrigation.
Of these water-saving technologies, drip irrigation is of particular importance.
