Efficient use of water resources to increase agricultural production of rice

Abstract

Abstract The construction of the Krasnodar reservoir has significantly increased the volume of replenished reserves of pressure underground water, which contributes to improving the efficiency of the use of water resources in the Kuban River basin. Relevance in improving the efficiency of water resources in the basin of the river Kuban to develop new solutions to the agricultural production of rice ensures the quality of products and crop stability. The problem of water quality is very acute. In the Kuban River basin, the annual runoff is subject to vertical zoning, and there is a regular decrease in the annual runoff modulus with a decrease in the average height of the catchment area and along the length of the watercourse. The most effective control is the construction of treatment facilities and the biological method of control in areas of reservoirs with low water exchange. Phosphates are pollutants of artificial origin. The content of phosphates in the reservoir on average exceeds the MPC 1.5-2.0 times. The analysis of available data on bacteriological and parasitological studies gives an idea of the current state of water resources. The results of laboratory tests showed that no parasitological contamination of the water was detected. Bacteriological contamination is present in all parts of the reservoir. The main type of contamination is the excess content of coliform bacteria.
