Abstract

Use: clarification of coniferous forest cultures. The essence of the method: during the period of winter frosts, the crust of unwanted rocks is destroyed along the trunk by shock working bodies - a chain, a cable, a rod. 1 hp f-ly, 1 tab.

Description

The invention relates to agriculture and forestry, in particular for the clarification of forest cultures.

There is a method of suppressing the growth of forest shrub vegetation by cutting it. The disadvantage of this method is that, in essence, planting of trees and shrubs is carried out on a stump, as a result of which undesirable growth quickly grows again and numerous turns are required, often in 2-5 years.

There are known techniques (prototype) of suppressing the growth of trees by applying wounds. The bark of trees is cut by a ring or on the one hand, while at work in the frosty period, the trees may shrink as a result of frost damage. A large amount of snow makes work difficult. The disadvantage of this method is the large labor intensity when cutting the bark with rings or on one side.

The aim of the invention is to reduce labor costs during the clarification of forest crops, in particular conifers.

The goal is achieved by the fact that in a known method of suppressing the growth of trees, including cutting the bark with rings or on the one hand, the bark of unwanted species is destroyed by impacting tools, and a chain, cable or rod is used as the impacting tool.

The work to suppress the growth of trees and shrubs is carried out in such a sequence.

After the onset of constant negative temperatures and deep dormancy in unwanted tree-shrub vegetation, the destruction of the bark along the trunks is carried out with partial toppings of the tops with percussion working elements made in the form of a chain, cable or rod. The work can be carried out until the coniferous crops are completely covered with snow, and since often porosities are used to manually remove the porosity or a Secor type brush cutter. In this case, the backstage of the hardwoods looks good when the crops are completely falling asleep and the work can be continued quite effectively further. The application of this method leads to a weakening of the growth

its further drying in winter also increased, reducing damage to the soil and root systems of the planted seedlings by the tractor engines and machine supports.

Example. Lightening is carried out by a chain brush cutter after the onset of constant negative temperatures and deep dormancy in undesirable tree-shrub vegetation. The frequency of rotation of the chain cutter of the brush cutter is chosen such that the height of the remaining growth is on average 40-50 cm and the bark of the growth is destroyed. In the case of good visibility of leafy hardwoods, work can be carried out even after the cultural plant is completely covered with snow.

way. The height of the shoots during the processing period was 1.5-1.8 m.

Processing of crops according to the proposed method reduces the required power by 30-50%, and saving money by reducing the number of treatments reaches 30-50 rubles per 1 hectare.

Claims (2)

1. A method of suppressing the growth of trees, including mechanical damage to the bark along the trunk during the winter frosts, characterized in that, in order to reduce labor costs in lightening softwood cultures, the bark of unwanted species is destroyed by impacting working bodies. 2. A method according to Claim 1, characterized in that a chain, a cable or a rod is used as the shock working bodies.
