Abstract
Due to the rapid growth of the world's population and intensive economic development, the demand for natural resources, including water and land, is growing day by day. According to the UN, around the world, wheat is grown on an area of 217.71 million hectares, and at the same time, 6.4-7.8% of the total area is using the subirrigation method. The article presents the results of experiments on the widespread use of groundwater for irrigation of lands with a low level of groundwater and salinity of 1-3 g/l in the conditions of meadow gray soils of the Syrdarya region.
Highlights
Scientific research aimed at improving the management of reclamation regimes in the world is of great importance
Effective ways to solve these problems are to meet the needs of agricultural crops in water at the expense of groundwater and to ensure moistening of the active soil layer based on the control of the water level in the ditches [4, 5, 11, 12,13,16, 17]
Controlling the reclamation regime, the groundwater level was artificially raised to a depth of 1.0 and 2.0 m by blocking the main trenches
Summary
Scientific research aimed at improving the management of reclamation regimes in the world is of great importance. In this regard, it is important to develop new methods for the effective and targeted use of groundwater to increase the productivity of irrigated agricultural land and eliminate water shortages during the growing season. In our country, including in the conditions of meadow gray soils of the Syrdarya region, the widespread use of groundwater for irrigation of lands with a low level of groundwater and salinity of [1,2,3] g/l helps to reduce water deficit during the growing season.
