Description

The invention relates to methods for destroying stumps when converting felling to agricultural crops, as well as for reforestation, for example, when creating an orchard and plantation forest, as well as fruit-bearing crops.

A known method of uprooting stumps on the author. St. No. 1501977, which includes pretreatment of the root system by applying a nitrogen-containing chemical improver to the soil, holding in time and extracting the stub root

This method is implemented using such technical means that include spring spreading of the chemical improver over the area, loosening of the soil after a certain period of time and rooting out of stumps at the final stage. In this case, environmental damage is inevitable.

There is also a known method of destroying stumps according to ed. No. 899010, including drilling holes in a stump and introducing into the holes a chemical solution that ensures the destruction (decomposition) of stumps

However, the known method is not effective enough due to insufficient decomposition of the stumps at a low consumption of a chemical solution and environmental damage due to the introduction of large doses of a chemical solution, and due to insufficiently high labor productivity due to the need to drill several holes in each stump and then fill them with chemical solution

The aim of the invention is to increase labor productivity and accelerate the process of decaying stumps without disturbing the environment.

This goal is achieved by the fact that at least a chemically and biologically inert (inactive) porous substance is applied to the upper surface of the fresh bum. A long-lived, quick-hardening foam from a polymeric material is processed as a porous chemical substance by treating the ground part of stumps in addition. colors and the lateral surfaces of stumps are additionally infected with saprophytes

Fig. 1 shows a stump coated on top with quick-hardening foam and infected laterally with saprophytic fungi. Fig. 2 shows a stump treated with foam from above and from the sides, that is, along the maximum surface of the aerial part.

The method can be implemented as follows

The upper surface of fresh mon 1 is coated with a rapidly hardening foam, preferably of a dark color consisting

for example, from synthetic foams based on urea resin 2. In this case, the quick-hardening foam 2 ensures the accumulation of heat and moisture on the surface of the foam, inside it and under the bark. The living roots of fresh montranspire moisture from the soil to the stump itself, and the cap coat of long-living, quickly solidified, dark-colored Tttins prevents the evaporation of moisture and accumulates solar radiation, while the wood inevitably becomes saturated with moisture and the temperature increases. In addition, snow and rain moisture does not roll off the surface of the stump, but is absorbed due to the loose, pure porous structure of the foam. In addition, the hardened resin on the surface of the monopolymer prevents the formation of a solid resinous crust from the sun which has sunk, spilled over the surface of the monopolymer and then hardened natural resin, thereby preventing reflection of raindrops from the surface of the monopolymer and increasing its humidity. As a result of the influence of a complex of factors, the necessary conditions are created for intensive digestion of mon:

accumulating heat to a temperature of 30-50 ° C;

battery qi moisture

providing shadow protection from exposure to direct sunlight.

To further increase the efficiency of decomposition of stumps 1, their lateral surfaces are pre-infected with saprophytzmi fungi at sites 3. Decomposition of wood by fungi is accompanied by an increase in the moisture capacity of wood and intensifies the process of its further decay.

Accelerated decay of stumps accelerates decay of other wood in the felling area, including deadwood, unrealized low-product wood and felling residues, due to the inevitable spread of rot rot and saprophytes in the felling area

Thus, the simultaneous use of a complex of factors in the proposed method leads to intensive decay of the stumps and wood residues until they are completely destroyed without much labor. Wherein

there is an increase in labor productivity due to the exclusion of operations for drilling holes in the pits; the vitality of the roots of fresh stumps, which continue to transport moisture from the soil to the wood, is used to preserve the wood;

natural wood energy in the form of solar radiation and precipitation is also used to pebble wood;

soil moisture, precipitation, and solar heat accumulate in monks under a porous cap of rapidly solidified and long-lived dark-colored foams;

under conditions of sufficient heat and moisture, an intensive process of wood rotting takes place;

wood decay creates conditions for the viability of saprophytic fungi, which, in turn, further enhance the decomposition of wood;
