Description
Изобретение относитс к е-ельскому хоз йству , в частности к мелиорации.FIELD OF THE INVENTION The invention relates to an e-economy, in particular to land reclamation.
Известен способ промывки засоленных почв, включающий затопление поверхности почвы, внесение химического мелиоранта и отвод воды с растворенными сол ми непосредственно с поверхностиПТ и С2.1.A known method of washing saline soils includes flooding the soil surface, introducing a chemical ameliorant and discharging water with dissolved salts directly from the surface of PT and C2.1.
Недостатком известного способа вл етс низка эффективность рассолени почв в результате длительности процесса затоплени больших объемов воды и неравномерности промывки.The disadvantage of this method is the low efficiency of soil desalinization as a result of the duration of the process of flooding large volumes of water and uneven washing.
Цель изобретени - повышение эффективности рассолени .The purpose of the invention is to increase the effectiveness of desalinization.
Цель достигаетс тем, что затопление поверхности почвы осушествл ют путем подн ти и поддержани на заданной высоте уровн грунтовых вод с последующим перемешиванием верхнего сло .почвы, причем уровень грунтовых вод при затоплении поддерживают на высоте 0,7-0,8 м от поверхности земли, а затопление поверхности почвы производ т до образовани сло воды 0,3-0,5 м.The goal is achieved by flooding the soil surface by raising and maintaining the groundwater level at a given height followed by mixing of the upper layer of the soil, while the groundwater level is maintained at a height of 0.7-0.8 m from the ground when flooded. and the flooding of the soil surface takes place before the formation of a water layer of 0.3-0.5 m.
Сушность способа заключаетс в следуюшем .The dryness of the method is as follows.
Производ т подъем грунтовых вод под давлением через временные скважины или дрены до глубины 0,7-0,8 м. Разравн.ивают и нарезают оградительные валики (чеки) мелиорируемых участков. Затем внос т химический мелиорант в виде раствора и производ т перемешивание промываемого сло при наличии на поверхности почвы вод ного сло 0,3-0,5 м. После отстаивани вода с растворенными сол ми непосредственно отводитс с поверхности чеков.Groundwater rises under pressure through temporary wells or drains to a depth of 0.7-0.8 m. Fence rollers (checks) of the reclaimed areas are cut and cut. Then a chemical ameliorant is introduced in the form of a solution and the washed layer is stirred in the presence of a water layer of 0.3-0.5 m on the soil surface. After settling, the water with the dissolved salts is directly removed from the surface of the checks.
Дл достаточного рассолени , в зависимости от степени и характера профил засолени , процесс подачи воды, перемешивание и отвод воды с растворенными сол ми повтор етс 3-5 раз.Depending on the degree and nature of the salinization profile, the process of water supply, mixing and removal of water with dissolved salts is repeated 3-5 times for sufficient salinization.
Поскольку предлагаемый способ промыв ки св зан при необходимости с искусственным подъемом и поддержанием грунтовых вод, целесообразно проводить промывку па возможно большой территории одновременно дл интенсивности механизированных промывок и в теплое врем года дл no.iyчени высокой концентрации и легкой lacrворимости солей в воде.Since the proposed washing method is associated, if necessary, with artificial raising and maintenance of groundwater, it is advisable to wash the pas of as large a territory as possible at the same time for the intensity of mechanized washes and in the warm season for high concentration and easy lacidity of salts in water.
