RU2524180C1 - Method of sand fixation by planting large-sized seedlings of eurotia using side-scenes from cane fibre boards - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: in this method the sand is fixed by planting large-sized seedlings of eurotia using the side-scenes from cane fibre boards. The work is carried out on the open sands using grey eurotia as sand binding culture. Forage Kochia, Siberian wheatgrass are seeded under protection against pouring the side-scenes from eurotia. At that the large-sized eurotia seedlings are planted by planter along the axes of the tapes. Then to protect the grey eurotia seedlings against pouring with sand the cane fibre boards are used, stacked with support on each other along the rows.

EFFECT: method enables to improve the efficiency of phytomeliorative works carried out using cane fibre boards on open sandy areas and degraded pastures.

Description

The invention relates to agriculture, in particular to methods of phytomelioration of desertified lands.

There is a method of creating pasture on sand (RU 2053617, publication date 02/10/1996), which consists in phased cultivation of Issamophyte crops. This method is the closest technical solution, according to which sandy oats are sown step by step, then leafless juzgun and teresken gray, then prostratus thistle, Siberian wheatgrass and white wormwood are sown.

The similarity lies in carrying out work on open sands, in using gray teresken as a sand-strengthening crop, and sowing a prostrate, Siberian grain, protected from falling asleep backstage from teresken.

The disadvantage of this method compared to ours is the low percentage of survival of plants due to falling asleep with sand (burial) or exposure of the root system, wind drift and death of seedlings. With this method, the wind regime was very important. Our method eliminates this drawback.

The tasks to which the invention is directed are combating desertification, biological degradation of pastures and creating obstacles to the movement of sand.

The technical result is an increase in the efficiency of phyto-reclamation works carried out using reed plates in open sand massifs and degraded pastures.

This technical result is achieved by the fact that the work is carried out on open sand using teresken gray as a sand-strengthening crop and sowing a prostrate, Siberian grain, protected from falling asleep from the teresken wings, and is characterized by the fact that large-sized seedlings of teresken are planted along the axes of the tapes, then in order to protect the gray teresken seedlings from falling asleep with sand, reed plates laid with support on each other along the rows are used

Disclosure of invention

Depending on the chosen terms of work (autumn-winter), soil preparation for planting teresken seedlings is carried out either in March-April or in November. The following machines and assemblies are used for this technological operation: DT-75 + Paraplau-PRB-4-35 plow. The work is carried out in the destructive and accumulative areas of the centers of deflation. When performing work, the following technical parameters are observed: soil treatment is carried out to a depth of 35-40 cm with tapes 1.4 m wide. The distance between the axes of the tapes is 5 m.

Further, in the same time frame, the following technological operations are carried out:

- Preparation of seedlings of teresken for planting. At the same time, trimming and trimming of the trunks of the root system is carried out, and the roots are treated in slurry-earthen slurry.

- Planting seedlings. For this technological operation, the following machines and assemblies are used: MTZ-80 + SLCH-1. Large-sized seedlings of teresken are planted with a planter along the axes of the tapes. Further, in order to protect the gray teresken seedlings from falling asleep with sand, reed plates laid with support on each other along the rows are used. Our proposed innovative use of reed slabs, which will act as a mechanical barrier to the wind, will reduce wind speed, prevent sand falling (burial), and also expose the root system, many times reduce the likelihood of wind drift and death of seedlings, and will prevent transfer particles of sand, helps to plant seedlings after planting. In the course of planting, the worker evens out the seedlings and corrects the planting of the roots. The work is done manually. In order to create pastures in subsequent years in areas protected from sand by using scenes from teresken, it is planned to introduce a prostrate and Siberian wheatgrass into the grass barley.

The economic effect (result) will be obtained due to:

- increase the survival rate of teresken seedlings from 30% to 70%;

- the cost of feed on restored land;

- feed preserved on pastures adjacent to desertification foci as a result of protection against falling asleep with sand;

- sustainability of multicomponent pastures in comparison with degraded lands on which the process of overgrowing occurs naturally;

- additional livestock products obtained by increasing the productivity of forage land.

Claims (1)

A method of fixing sand by planting large-sized seedlings of teresken using curtains from reed slabs, including work on open sands using gray teresken as a sand-strengthening crop and sowing barbed prostrate, Siberian grain, protected from falling asleep rocker from teresken, characterized in that it is large teresken is planted with a planter along the axes of the tapes, then to protect gray teresken seedlings from falling asleep with sand, reed plates laid with support are used each other along the rows.
