DETERMINATION OF THE DEPTH OF SOIL MOISTURE IN THE FOOTHILLS.
Keywords:water saving, orchards and vineyards, irrigation rate, duration of irrigation, method of irrigation, cuttings of grapes, drip irrigation, biological needs of the plant
The article is devoted to the results of field experiments carried out to improve water-saving technologies in horticulture and viticulture and to develop irrigation standards based on the management of the water-physical properties of the soil in the foothills. At the same time, in the drip irrigation system, the water consumption of droppers is set at the rate of 3-4 liters per hour, 30-40 liters per tree in the first year to moisten 50 cm of soil, in the second and third years up to 100-140 l to moisten 70 cm soil. Establishment of norms and timing of irrigation based on the biological needs of plants when irrigating orchards and vineyards in irrigated areas of Uzbekistan, increase the efficiency of irrigation water use by 15-18%, reduce labor and other costs. % reduction.
