“…To apply a polymer -polymer complex solution to the soil surface, a system wаs used with a slight re-equipment for the introduction of herbicides, installed on a tractor with a seeder for sowing cotton with a flow rate of 0.6-0.8 l/m2. The event is cаrried out simultaneously with spraying with herbicide on the soil surface during cotton sowing and before each irrigation when cutting furrows (see Figure 1) [12][13][14][15][16][17].…”

The problem of global climate change is on the agenda of mankind, not only because of the average annual temperature rise on the planet but also because of changes in the entire geosystem, rising global oceans, melting ice and permanent glaciers, increasing uneven rainfall, changing river flow patterns and climate instability, other changes involved. The world pays special attention to research work to develop technologies for the management and efficient use of water resources. In particular, it is important to conduct research to develop new water-saving irrigation technologies using cheap and chemical, and technical means.

Ecosystem vulnerability increases significantly when anthropogenic factors overlap with the effects of adverse climate change, which together negatively affect biodiversity and ecosystem functioning. According to ADB forecasts, the inflow to the lower reaches of the Amu Darya will decrease by 26-35% by 2050. The combined effect of higher water demand and lower inflow will increase the current water shortage - the annual water shortage will increase to 50% of the total demand. In connection with the projected changes, the current state of water resources of the Amu Darya river, as well as the need for the socioeconomic development of the region, the task of assessing the projected impact of climate change on the availability and quality of water resources becomes urgent.

“…The technical condition of the closed and requiring drainage reconstruction in the region as of January 1, 2019, in the administrative regions is given in Table 1. The calculation of horizontal drainage consists of establishing the depth of the drainage, determining the inter-drainage distances, and the drainage module (l/s) from one ha of the drainage area [12][13][14][15][16].…”

The article is devoted to the reconstruction of existing old drainage systems in order to radically improve the reclamation ecological and sanitary conditions of the lands of the Jizzakh region to improve the social conditions of the population and obtain high stable yields of cotton and other agricultural crops. As a result of many years of theoretical and irrigation to experimental research, operational monitoring in farms in the Pakhtakor district of Jizzakh region. The parameters of the primary horizontal drain are determined based on the analysis of reclamation climatic, soil, geological, hydrogeological, hydrological, economic, and other conditions. The calculation of the reconstruction of horizontal closed drainage is based on the method of A.N. Kostyakov in intensity from working the groundwater level after flushing. The depth of the drainage was determined, taking into account global climate change in recent years; based on these changes, an adjustment was made in the calculations to determine the value of the critical depths of groundwater during the operation of drainage systems. The incoming and outgoing parts of the water balance of the experimental plots were determined. In the presence of pressure groundwater, the size of the supply of groundwater with pressure water is determined. More proposed by the V.N. Shestakov's formula.
