Abstract

Зимний приствольный радиационный барьер представляет собой устройство в виде полотна из воздухопроницаемого и водопроницаемого материала с диффузной отражательной способностью, близкой к альбедо свежего снега, в форме круга, квадрата, овала, сегмента и иной плоской фигуры для расстилания на почву в приствольной зоне дерева или куста, что обеспечивает при оттепели и отсутствии снега днем отражение солнечной энергии от внешней поверхности барьера и защиту почвы от избыточного прогрева, а ночью - отражение в почву от нижней поверхности барьера теплового излучения земли в основном в инфракрасной области спектра, что предотвращает радиационное выхолаживание почвы в приствольной зоне.The winter near-barrel radiation barrier is a device in the form of a sheet of breathable and water-permeable material with diffuse reflectivity similar to the albedo of fresh snow, in the form of a circle, square, oval, segment and other flat figure for spreading on the soil in the near-tree zone of a tree or bush, This ensures that during thaw and no snow during the day, solar energy is reflected from the outer surface of the barrier and the soil is protected from excessive heating, and at night it is reflected into the soil from the lower surface of the ba the thermal radiation of the earth is mainly in the infrared region of the spectrum, which prevents radiation cooling of the soil in the near-trunk zone.
