Abstract

FIELD: forestry.

SUBSTANCE: invention relates to forestry, namely to growing of stable highly productive crops of siberian cedar in environmental purposes. Method includes division of area of forest into cultural strips and strips of natural recovery, partial treatment of soil, planting of 4–5-year consolidated seedlings. Culture is created on lands not under agricultural use. Cutting is performed in strips of natural recovery, width of silvicultural strip is defined equal to 35–45 m, natural recovery strip is 10–14 m, arrangement of long side strip is directed from North to South.

EFFECT: method allows to create stable culture of siberian cedar in environmental purpose and intermediate production of wood in strips, left for natural recovery.

Description

The invention relates to the field of forestry, namely to the cultivation of sustainable highly productive crops of Siberian pine pine Siberian nature conservation.

A known method of creating partially continuous landscape crops of Siberian cedar on clearings in the European part of Russia (US Pat. No. 2201072). The method includes a breakdown of the felling area into forest-cultural landscape plots and natural regeneration plots. Partial cutting of stumps to a level with the soil surface is carried out, partial tillage by disking or furrowing or partial crushing of stumps with simultaneous tillage is carried out. After this, 3-4-year-old seedlings or 5-7-year-old seedlings are planted in forest-cultivated landscape areas. In this case, the width of the forest-cultural landscape site is determined to be equal to 4-6 diameters of the crown of Siberian cedar, taken into account at the age of its main felling. The width of the natural renewal site is determined equal to 2-3 diameters of the crown of Siberian cedar.

This method has several disadvantages. The basis of the choice of the width of the forest-cultural landscape plot (hereinafter the strip) is the crown width at the age of the main cutting, and the following parameters of the strip width and natural regeneration sites are given (table 1):

In the course of studying forest cultures of Siberian cedar at the age of 100, growing in quarter 9, division 20 of Dubravny district forestry of the Rutkinsky forestry of the Mari El Republic, it was found that there is a direct relationship between the preservation of crops and the width of the plot (table 2).

With a decrease in the width of the forest-cultural strip from 30 to 20 meters, the safety of cedar crops decreases and is equal to from 4.7 to 3.4%. With a width of less than 20 meters, the safety indicator approaches zero.

The location of the long side of the forest cultural plot relative to the cardinal points is also not taken into account. It was experimentally established that trees with maximum trunk diameter values were observed on the site from the north side under conditions of sufficient illumination during the start of crop production.

The technical result is to create a sustainable Siberian pine culture of Siberian nature conservation, intermediate receiving wood in the bands left for natural regeneration.

The technical result is achieved by the fact that the method of creating strip crops of Siberian pine pine includes breaking the area into forest and natural regeneration bands, partial tillage, planting of 4-5-year-old enlarged seedlings or seedlings. According to the invention, crops are created on lands that have been abandoned for agricultural use, natural regeneration is cut down in the stripes, the width of the forest-cultural strip is determined to be between 35 and 45 m, and the width of the natural regeneration strip is 10 and 14 m; the long side of the strip is oriented north to south.

The drawing shows a method of creating strip crops of pine cedar.

The area is marked with landmarks on plots: forest-cultivated and natural regeneration, with a length from north to south. In this case, the width of the strips is equal for cedar from 35 to 45 m, and for natural regeneration - 10 and 14 m. On forest cultivated strips, the natural regeneration of tree and shrub species is completely removed. The following is a partial tillage.

When landing along the edges of the forest-cultivated strip, a strip of 3-4 m is left, which serves as a protective zone. The distance between the rows is 2.5-3.0 m, and the seats are 1.0 m. For planting, enlarged seedlings or seedlings of 4-5 years are used. Agrotechnical cares are carried out for 4 years: 1 year - 3 times, 2 years - 2 times, 3 years - 1 time. For 20-30 years, as needed, forest-related cedar care is carried out, avoiding oppression, because it is inferior in terms of growth to local tree species (pine, birch, aspen).

The application of this method allows you to create sustainable cultures of cedar for environmental purposes, intermediate receiving wood in the bands left for natural regeneration.
