Abstract

A METHOD FOR CREATING AN ERIPOUS FOREST STRIPES PROTECTION, including planting woody plants on trails with a longitudinal slope, forming bridges and creating shafts on the bottom onyi shk & The rows of woody plants LAYOUT the forest plots at an angle to the horizontal of the terrain, reversing the slope of the forest line, make jumpers in the process of caring for them, and create a height of 1.5-2.0 times the height of the jumpers.

Description

H366peteHHe relates to agriculture, in particular to the protection of soils from erosion by forest reclamation methods.

Known way to create forest companies | There are no horizontal lines or cbd lines at different elevations, followed by rolling them along the lower edge. However, the water regulating ability of forest belts remains low due to the short flow of local runoff under the forest canopy, equal to its width ..

There is also known a method for creating water-regulating forest belts with a longitudinal slope, including planting forest strips, banking them along the lower edge and making spurs across the forest strip 2.

However, this method requires a large expenditure of labor and resources in the construction of spur jumpers in the forest belt. In addition, the drainage path along the bridges with their cross-sectional research institutes is the shortest, which limits the water absorption capacity of the forest belt.

The purpose of the invention is to increase water absorption in forest belts and reduce the cost of their creation.

This goal is achieved by placing trees in the forest belt at an angle to the horizontal of the terrain, opposite to the slope of the forest belt, the pegs are formed in the process of caring for races, and the shafts are created with a height of 1.52, 0 times the height jumpers. . The drawing shows an implementation scheme of the proposed method. The method is carried out as follows. . - ;. , -,

On the projected route of the anti-energy forest belt, passing with yiuioHOM, they are planted, for example, using forest machines SLT - 1, SLN-2, etc. - rows of tree species 1, and the rows are stirred at an angle to the horizontal and mestorrst 2, opposite trail slope

forest belts (upl ji). In this case, the slopes of the rows are chosen, based on the avoidance of the eroding and pouring speeds of the water flow along them, which, depending on the type of soil, varies within 5 0.005-0.001.

During the growing season, cultivators, for example, KRL-1 and KPT-3, make care of the soil in rows and aisles, during which they form land shafts 3 of height 15-20 cm along rows of plants. An important prerequisite for carrying out of-care is the destruction of the napasa, which is formed during the processing of the fields along the forest strip.

5 After termination of soil maintenance, coi are made, for example, with a bulldozer or plows of the main water guide shaft 4 along the lower edge of the forest belt. At the same time, the working height of the shaft 4 is 30-40 cm. When snow melts or when there is showering water, the local runoff, the stack from the slope (along arrow a) is normal relative to the contours of the terrain 2, enters the forest belt and spacing m along the jumpers 3 Move {along arrow 6} to main shaft 4. Outflows of drain flow (along arrow c) along main shaft 4 to spillway device 5 Unimpeded and uniform flow of thawed and rainwater into the forest belt and an increase in its path along p Dov increases water absorption of soil by 20-30 / o. This allows a 2 to 4-fold reduction in the cost of the handicraft of water-dispensing devices (chutes, consoles, drainage walls) by reducing the number of such devices. An increase in the length of the forest carrying unit of forestry equipment by 2–10 times increases the productivity of machine-tractor units by 10-12%. In addition, the proposed method makes it possible to completely exclude the seizure of: valuable arable land from one land use account for hydrographic

0 of whom there is a foundation to significantly increase the growth and improve plant growth due to their better moisture supply.
