Description

известны способы улучшени  стррту|Я2 почв путем внесени  струитурообразователей (структоров). В результате внесени  струвторов улучшаетс  водно воздушный режим поч что способствует лучшему росту рельс вохоз йственных растений, а тавхе предотвращаетс  арози  почв. Известно использование в качестве структоров лигносульфонатов отходов целлюлозно«бумакной промышленности . Однаво вав струвторы лигно сульфонаты налозффевтивны в дл  достижени  заметного отрувтурирующего эффекта требуетс  внесение больших количеств, что сопр жено с большими расходами на перевозку. Кроме того, при внесении в почву больших количеств лигносульфонатов возьюжао про вление их угнетащего действи  на почвенную флору и фауну. В качестве структоров известно, например, использование водных дисперсий синтетических полимеров и сополимеров и/или сополимеров с добавлением различных веществ. В известных способах используютс  в качестве основного действующего компонента синтетические полимеры, которые в насто щее врем  экономически недоступны дл  широкого применени . Вместе с тем синтетические полимеры очень быстро тер ют эффективность как структоры в результате процесса старени  полимеров (действие солнечной уфкрадиащш, атмосферного озона, ионов переходных металлов), а также действи  почвенных микроорганизмов. При этомThere are known ways to improve soil buildup | H2 through the introduction of structural agents (structures). As a result of the introduction of struvtors, the water-air regime of the soil improves, which contributes to a better growth of the rails of the state-owned plants, and the soil is prevented from spreading. It is known to use pulp waste from the paper industry as lignosulfonate structures. However, ligno-sulphonate struc- tures are nano-effi- cient in order to achieve a noticeable branching effect, large amounts are required, which is associated with high transportation costs. In addition, when large amounts of lignosulphonates are introduced into the soil, their depressant effect on the soil flora and fauna is shown. As structures, it is known, for example, to use aqueous dispersions of synthetic polymers and copolymers and / or copolymers with the addition of various substances. In the known methods, synthetic polymers are used as the main active component, which are currently not economically available for widespread use. At the same time, synthetic polymers very quickly lose their effectiveness as structures as a result of the aging process of polymers (the action of solar radiation, atmospheric ozone, transition metal ions), as well as the action of soil microorganisms.
