Influence of cotton irrigation with drainage water on the soil reclamation regime

The article presents the results of a study of the influence of land reclamation regime due to cotton irrigation, biological reduction of the salinity of collector-drainage waters using aquatic plants to create additional water sources, irrigate crops, and obtain sustainable results yields in conditions of water shortage. Experience increased mineralization of drainage water in the small ponds. From water plants, such as Lemna minor, Azolla caroliniana and Eichhornia crassipes. When analyzing the salt regime of the soil, the content of chlorine ions in the control variant with direct irrigation with drainage water at the end of the growing season was 0.034%. With the method of reduced mineralization using aquatic plants, the content of chlorine ions in the soil was 0.025-0.029 %. It is less salt build-up. The yield of cotton was 31.9 c/ha in the control variant and more than the control 7.9-8.4 c/ha in other experiment variants.
