Применение различных мелиорантов для изменения водно-физических свойств солонцов сульфатно-содового засоления

Применение различных мелиорантов для изменения водно-физических свойств солонцов сульфатно-содового засоления

Abstract

Рассмотрена эффективность применения различных мелиорантов на фильтрационную способность солонцов сульфатно-содового засоления при различных дозах. Установлено, что действие реагентов-мелиорантов на фильтрационную способность было неодинаковым. Самыми эффективными мелиорантами, обеспечивающим наивысшее значение фильтрационной способности изучаемых образцов солонца, оказался хлористый кальций (CaCl2) в дозе 0,4г на 40г почвы, количество фильтрата составило 84 мл в сутки. При внесении фосфогипса в дозе 1г на 40г солонца, количество фильтрата составило 81 мл в сутки. Минимальное значение фильтрационной способности в лабораторных исследованиях нами было установлено при внесении сернокислого железа (FeSO4∙7H2О) в дозах от 0,6 до 1,2 г на 40г почвы, количество фильтрата составило всего 62 мл в сутки (таблица 1).

Examined the effectiveness of different ameliorants on the filtration ability of solonetzes sulfate-soda salinity at different doses. It is established that the action of reagents-ameliorants on the filtration ability was different. The most effective improver providing the highest value of the permeability of the studied samples saltwort was calcium chloride (CaCl2) at a dose of 0.4 g per 40 g of soil, the filtrate was 84 ml per day. When making phosphogypsum at a dose of 1G on 40g of saltwort, the filtrate was 81 ml per day. The minimum value of permeability in laboratory studies it was found when adding iron sulfate (FeSO4∙7H2О) in doses of 0.6 to 1.2 g per 40 g of soil, the amount of leachate was only 62 ml per day (table 1).
