| Popis: | In the article, studies were conducted on the economy of quality saline washing and irrigation water of saline soils by deepening medium coarse soils with a mechanical content of melioration, plaster, salinity in the conditions of Bukhara region. In experiments, basically, there were three ways to soften the field: plowing in the first experiments at a depth of 35 cm, plowing in the second experiment at 60 cm, and plowing in the third experiments at a depth of 80 cm. During the experiments, in the first variant of the studies, the norm of salt washing was set to 6480 cbm/ha, in the second variant to 5210 cbm/ha and in the third variant to 5010 cbm/ha. First studies in irrigation of Bukhara included 102 varieties, that is, in the control variant to 5821 cbm/ha, in the second variant to 5284 cbm/ha and in the third variant to 5100 cbm/ha. They were watered 5 times during the season. At the same time, high quality cotton was harvested due to the increase in the cotton yield to 0.39 t/ha in variant 2 and 0.129 t/ha in variant 3 compared to the control. And the land reclamation situation improved. The amount of chlorine ion in the active layer is 0.003 in variant 2 compared to the control. The amount of dry residue decreased by 0.058% in variant 2 and the amount of dry residue by 0.063% in variant 3. |
