RU2590820C2 - Winter nearwellbore radiant barrier - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention is intended for use in gardening, decorative gardening in periods of absence of snow cover during winter and prevernal thawing weather and frosts. Winter nearwellbore radian barrier is made in the form of a cloth of air-permeable and water-permeable material. Diffuse reflectance of the material is close to the fresh snow albedo. Barrier is made in the form of a flat shape for spreading on soil in the tree or bush nearwellbore area. Solar energy reflection from the outer surface of barrier in the daytime protects the soil in the tree or bush nearwellbore area from excessive heating. It also protects plants against early sap flow.

EFFECT: reflection at night in soil from the barrier lower surface of the thermal radiation of the Earth, mainly in the infrared region, which prevents radiation cooled thoroughly soil in the tree or bush nearwellbore area.

The invention as a technical solution

In winter, in the horticultural regions located within minus mid-January isotherms, a stable snow cover with a high albedo serves as a natural radiation barrier that protects the soil from both excessive solar radiation and strong freezing. However, during periods of severe thaws occurring in late autumn, winter, and early spring, snow cover in gardens and parks sometimes almost completely melts, especially in the near-trunk zone of trees and bushes, exposing the soil around the trunk. If after the thaw frosts occur in an anticyclone without clouds and precipitation, then the soil exposed around the trunks during long cloudless winter nights quickly freezes, primarily due to intense radiation cooling. Especially dangerous is such a change of weather in early spring, when the sun under an anticyclone and cloudless sky for longer days than winter warms up the soil exposed around the trunks, provoking the premature onset of sap flow and swelling of the kidneys, and at night with a cloudless sky there is a strong radiation cooling of the soil around trunks.

The objective of the present invention is to create around the trunks of garden trees and bushes an artificial radiation barrier with diffuse reflectance close to the albedo of fresh snow cover, which, on the one hand, will protect the soil around the trunk in the daytime from excessive warming by sunlight, and on the other hand, - will protect the soil from excessive radiation cooling at night.

The essence of the invention is the use of an artificial winter near-barrel radiation barrier located directly on the soil around the trunks of garden trees and bushes, which, on the one hand, should protect the soil around the trunk in the daytime from excessive warming by sunlight, and on the other hand, provide protection soil from excessive radiation cooling at night.

At the same time, the winter near-barrel radiation barrier must freely pass water and air, without interfering with the natural water and air exchange of the soil and preventing the occurrence of anaerobic processes in the soil, which allows it to be used without any harm to trees and bushes, from late autumn to spring, up to complete snow melting and thawing of the soil.

Technical result

The use of a winter near-barrel radiation barrier located directly on the soil around the trunks of garden trees and bushes provides, in the absence of snow during the daytime thaw, reflection of most of the solar energy from the outer surface of the barrier with diffuse reflectivity close to the albedo of fresh snow cover and protection soil from excessive heating, and at night the same barrier, with its lower surface, reflects into the soil the thermal radiation of the Earth mainly in the infrared region with spectrum, which prevents excessive radiation cooling of the soil in the near-trunk zone.

Due to this, during thaws in the near-tree zone of garden trees and bushes, sheltered by a winter near-tree radiation barrier, the soil is in the same conditions as under natural snow cover, that is, it does not thaw during the day and does not freeze much at night.

The implementation of the invention

The construction of a winter near-barrel radiation barrier located directly on the soil around the trunks of garden trees and bushes provides, during the thaw and absence of snow, during the daytime 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 thermal radiation barrier The Earth is mainly in the infrared region of the spectrum, which prevents radiation cooling of the soil in the near-trunk zone.

The winter near-barrel radiation barrier is a device in the form of a sheet of breathable and water-permeable material with diffuse reflectivity close to the albedo of fresh snow, in the form of a flat figure for spreading on the soil in the near-tree zone of a tree or bush, preferably in the projection of plant crowns, where a significant part of the surface root system of plants. At the same time, the material of the winter near-barrel radiation barrier should have resistance to decay, resistance to weak solutions of acids and alkalis of the soil, and durability for 1-2 or more seasons.

Claims (1)

Winter near-barrel radiation barrier, characterized by the fact that in the conditions of winter and early spring thaws and frosts that occur during periods without snow cover, in order to ensure the reflection of solar energy from the outer surface of the barrier in the daytime and thus protect the soil in the near-trunk zone of a tree or bush from excessive heating, and plants from the premature onset of sap flow, at night - reflection into the soil from the lower surface of the earth’s thermal radiation barrier, mainly in the infrared region of the spectrum and thereby preventing radiation cooling of the soil in the near-tree zone of a tree or bush, made in the form of a web of breathable and water-permeable material with diffuse reflectivity close to the albedo of fresh snow, in the form of a flat figure for spreading onto the soil in the near-tree zone of a tree or bush.
