Description

Изобретение относитс  к сельскому хоз йству и мелиорации, а именно к способам борьбы с эрозией почвы.The invention relates to agriculture and land reclamation, and in particular to methods of combating soil erosion.

Известен способ борьбы с эрозией почвы на склонах, заключающийс  в нарезке щелей поперек склона и засыпкой их рыхлой землей 1.A known method for combating soil erosion on slopes is to cut gaps across a slope and fill them with loose earth 1.

Однако известный способ недостаточно эффективен при значительных уклонах поверхности почвы.However, the known method is not effective enough with significant slopes of the soil surface.

Известен также способ борьбы с. эрозией почвы на склонах, заключающийс  в поделке земл ных валков ndперек склона 2..Also known way to deal with. soil erosion on the slopes, which consists in the creation of ground rolls nd cross slope 2 ..

Недостатком известного способа  вл етс  то, что он не обеспечивает предотвращени  потерь элементов питани  дл  сельскохоз йственных растенцй , эрозионных процессов почвы и накопление влаГи на склонах при стоке воды, так как ваЛки разрушаютс , особенно при большом потоке воды.The disadvantage of the known method is that it does not prevent the loss of nutrients for agricultural plants, soil erosion processes and accumulation of moisture on the slopes during water runoff, as the water is destroyed, especially when there is a large flow of water.

Цель изобретени  - уменьшение эрозионных процессов на участках склона и потерь элементов питани .The purpose of the invention is to reduce erosion processes in areas of the slope and loss of power cells.

Поставленна  цель достигаетс  тем, что поверхность валков и ло.жбину преимущественно со стороны стока воды покрывают слоем битумнб-полимерной эмульсии толщиной 2-10 мм..The goal is achieved by the fact that the surface of the rolls and the long edge, mainly on the water side, is covered with a layer of bitumen-polymer emulsion with a thickness of 2-10 mm.

На чертеже изображен предлагаемый способ, на котором 1 - поверхностный горизонт почвы, 2 - валок, 3 ложбина .The drawing shows the proposed method, in which 1 - the surface horizon of the soil, 2 - roll, 3 hollow.

Пример осуществлени  способа; Дл  этих целей с помощью специального приспособлени , установленного на машине, производ т срезание верхнего горизонта почвы навстречу друг An example of the method; For these purposes, using a special device installed on the machine, the upper soil horizon is cut to meet each other.

10 другу рабочим органом, в результате чего на поверхности горизонта 1 образуютс  ложбины 3 и между н гла формируетс  валок 2, затем со стороны стока воды поверхность валков и бину покрывают слоем сплошного водонепроницаемого материала - битумнополимерной эмульсией, обладающей способностью к затвердеванию, с толщиной сло  2-10 мм. Частично водонепроницаемый материал будет затекать и на другую сторону Всьлка.10 to another working body, resulting in troughs 3 are formed on the surface of horizon 1 and a roll 2 is formed between them, then from the water flow side the surfaces of the rolls and the bin are covered with a layer of continuous waterproof material - a bitumen-polymer emulsion having a hardenability; -10 mm. Partially waterproof material will flow to the other side of the Vslka.

Такое сплошное покрытие водонепроницаемым материалом надежн.о защищает валок от разрушительных действий стока воды во врем  обильных осадков и ветровой эрозии, а также укрывает почвенный слой, наход щийс  зй валком от разрушительных действий водной эрозии. Покрытие ложбины водонепроницаемым материалом- надежно защищает ее от образовани  оврагов. Кроме того, в такой ложбине происходит накапливание питательных веществ. По мере переполнени  ложбины влагой, часть влаги вместе с питательными веществами будет поступать в нижние слои почвы. Такие валки делают перед террасами на больших.склонах дл  защиты плодородного сло  терасс от разливани .Such a continuous coating with a waterproof material reliably protects the swath from the destructive actions of the water runoff during heavy rainfall and wind erosion, and also covers the soil layer, which is located by the swath from the destructive actions of water erosion. Covering a hollow with a waterproof material reliably protects it from the formation of ravines. In addition, nutrients accumulate in such a hollow. As the trough overflows with moisture, some of the moisture along with nutrients will flow into the lower layers of the soil. Such rolls are made in front of the terraces on large slopes to protect the fertile layer of terraces from spilling.

Рассто ние между валками зависит от крутизны склона, физико-химического состава почвы- и количества стекаемой влаги.The distance between the rolls depends on the steepness of the slope, the physicochemical composition of the soil, and the amount of moisture being drained.

Предлагаемое изобретение дает возможность значительно предотвра±ить смыв плодородного сло  почвы на склонах, а также не дает возможности образовани  оврагов и балок.The present invention makes it possible to significantly prevent flushing of the fertile soil layer on the slopes, and also does not allow the formation of ravines and beams.

Кроме того, такой способ позвол ет , повысить коэффициент использовани  минеральных удобрений в 2-3 разаIn addition, this method allows to increase the utilization rate of mineral fertilizers by 2-3 times
