Description

The present invention relates to the field of afforestation and may find application in the landscaping of streets and squares of cities and other settlements to ensure better preservation of thermophilic plants in the cold season.

When landscaping, as a rule, trees and shrubs are planted, adapted to the climatic conditions of the region. This greatly increases their resistance to adverse weather conditions. However, the diversity and decorativeness of vegetation is significantly impoverished.

A known method of storing plants in the cold season, which includes protecting plants with plastic shelters made in the form of a parallelepiped expanding downward (Pat. DE No. 10123238 A 1. "Inventions of the world" issue 1, No. 22. 2003) the Use of such Shelters allows you to maintain a winter temperature of 6-8 ° C inside them and ensure safety until the end of the cold weather. The disadvantage of this method is its limited use in regions with a relatively mild climate, where there is no significant freezing of the soil. In most of the territory of Russia, the depth of soil freezing in winter can exceed 1 meter. In this case, the installation of a shelter does not guarantee a successful wintering of heat-loving plants. At the same time, there is a problem of storage of shelters with a size of 2.2 × 1.7 m in the summer.

The closest to the proposed method of storage of plants in the cold season is the method according to the patent of the Russian Federation No. 1748700 A1, MK A 01 11/00, BI No. 27, 1992. According to this method, in the cold season, the root system is heated by supplying hot water through pipes laid underground. With this storage method, the conditions of wintering of plants are significantly improved even during prolonged cold winters.

However, the application of the known method is limited, since the moistening and heating of the soil surrounding the root system can be carried out only before removing the seedlings from the soil. Storage of seedlings in the cold season is carried out under a layer of frozen earth, the moistening of which is undesirable because of the danger of decay of the aerial part of the seedlings. Therefore, the known method can find application only when storing seedlings.

The objective of the present invention is to expand the capabilities of the known method and use it not only for storing seedlings, but also for storing perennial thermophilic plants in the cold season, as well as eliminating the cost of installing a heating network and heating water.

The solution to this problem is achieved by the fact that in the known method of storing plants in the cold season, including the supply of hot water through pipes laid underground, according to the invention, the plants are planted in containers, and in areas adjacent to thermal power plants, snow-holding barriers are formed (for example, forest belts ) and in the cold season they place containers with plants between them.

A positive effect of the application of the proposed method of plant storage in the cold season is that the formation of snow-holding barriers (for example, forest belts) and the placement of containers with plants between them in the cold season allows for better wintering of heat-loving plants due to the use of a milder microclimate that forms on areas, territories adjacent to thermoelectric power stations, fenced by snow-retardant barriers, due to utilization of heat losses a dense set w underground heat manifolds and heat generated by cooling towers, as well as shelter root layer of snow, delayed snegozaderzhivayuschimi obstacles.

Implementation of the proposed method for storing plants in the cold season is carried out in the following sequence: in the areas adjacent to the territory of thermal power plants, the formation of snow-holding barriers is carried out. These barriers can be made in the form of snow-retaining forest stands permeable to wind, planted in two or more rows over a distance of 25-50 m.

In cases where it is not possible to plant forest stands, barriers are made in the form of windproof snow retention shields.

Plants are planted in containers that are installed in spring or summer on landscaped streets, squares or near buildings. Before the onset of cold weather, these containers are transported to areas located near thermal power plants, and placed between snow-holding barriers. With the beginning of the heating season, the coolant will be supplied to the heated objects (residential buildings, administrative and other buildings), while part of the heat will be spent on heating the soil. When cooling the water entering the cooling tower, a significant amount of heat and moisture is also released. All this ensures the formation of a milder climate in territories adjacent to thermal power plants than in the rest of the city. With the onset of snowfall, due to a decrease in the wind speed by stands or shields, the snow will linger and accumulate between the snow-retaining stands or shields, filling the space between the containers. The formation of increased snow cover will not only protect the root system of plants from frost, but also reduce heat loss by the soil. It should also be noted that snow retention in the storage areas of containers with plants will reduce the amount of snow removal and removal from the territory of thermal power plants. In the spring, with the onset of positive temperatures, the snow in the storage areas will melt and after the disappearance of the snow cover, containers with plants are transported to the landscaping sites, where they can be until the next cold period of the year.

Thus, the application of the proposed method for storing plants in the cold season allows for better wintering of heat-loving plants, and also eliminates the cost of laying a special heating network by utilizing heat loss by a dense network of underground heating mains and heat generated by cooling towers, as well as covering the root system with a layer of snow held by snow retention barriers.
