RU2472331C1 - Grass surface based on tissue fabric - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can be used for protection against water and wind erosion of coastal benches. Grass surface based on tissue fabric comprises a fabric layer and a layer of nutrient mixture of organic and mineral fertilisers containing the seeds of perennial grasses. The fabric layer is made of cotton cloth with a open weave of threads and is reinforced with longitudinal and transverse straps with loops on the edges of the fabric. The layer of nutrient fertiliser mixture with seeds contains reinforcing, agglutinative and water-retaining components and is located on the fabric layer as separate "islets".

EFFECT: invention reduces the amount of tissue fabric and simplifies manufacturing of the grass surface.

Description

The invention relates to the field of applied ecology and can be used to create grass cover on the coastal slopes of the sea coast.

Known grass cover based on a flexible canvas (RU No. 2201069, IPC A01G 1/00, E02D 17/20, A01C 1/00, A01C 1/04, published 03/27/2003), including interconnected upper and lower fabric layers and the middle layer - seed carrier made of a pre-prepared nutrient mixture of fertilizers with seeds of plants, mainly perennial herbs. The nutrient mixture consists of the milled peat produced with the addition of complex mineral fertilizer containing nitrogen, phosphorus, potassium, in an amount of 0.8-1.2 kg per 1 m ^{3 of} peat or bioorganic fertilizer obtained from food waste processing, in an amount 1.2-1.5 kg per 1 m ^{3 of} peat at a rate of application of plant seeds 10-35 g / m ^{2 of} coating. The upper and lower fabric layers are made in the form of prefabricated panels of material that is intensively decomposed in the soil, mainly of flax fiber. The sheets are interconnected by needle piercing and / or stitching.

A disadvantage of the known grass cover based on a flexible canvas is the high consumption of fabric material and the complexity of its manufacture.

The objective of the invention is to reduce the consumption of fabric and simplifying the manufacture of grass cover by imparting a nutrient mixture of fertilizers with plant seeds reinforcing and adhesive properties.

The required technical result is achieved by the fact that in the known grass covering based on a fabric web, including a fabric layer and a layer of a nutrient mixture of fertilizers with plant seeds, it is proposed that the fabric layer be made of cotton paper with a rare interweaving of threads and reinforced with longitudinal and transverse ribbons with loops along the edges of the canvas, and supplement the layer of the nutrient mixture of fertilizers with seeds with reinforcing, gluing and water-retaining components and apply it to the fabric layer in the form of separate "islands" .

The invention is illustrated by drawings, where in Fig.1 shows a fragment of grass, and in Fig.2 is a section along aa in Fig.1.

In the drawings, the following notation:

1 - longitudinal threads of fabric (warp);

2 - transverse threads of fabric (weft), interwoven with the base;

3 - reinforcing tapes;

4 - “islands” of the nutrient mixture with seeds;

5 - tape loop for fixing the coating on the ground;

6 - seams;

7 - seeds of perennial herbs;

8 - reinforcing fibers.

The proposed grass cover (Fig. 1) contains a fabric layer made of cotton fabric with a rare interweaving of warp threads 1 and weft 2 and reinforced with longitudinal and transverse ribbons 3 connected by seams 6 to the fabric and provided with loops 5 along the edges of the canvas, and the layer nutrient mixture with seeds 7 (figure 2) is applied in the form of separate "islands" 4, intermittently located on the fabric and containing reinforcing 8, gluing and moisture-retaining components.

The basis of the nutrient mixture of the “islets” is the milled peat produced by the manufacturer with the addition of complex mineral fertilizer containing nitrogen, phosphorus, potassium, in the amount of 0.8-1.2 kg per 1 m ^{3 of} peat or bioorganic fertilizer obtained from the processing of food waste , in the amount of 1.2-1.5 kg per 1 m ^{3 of} peat at a rate of application of plant seeds - 10-35 g / m ^{2 of the} coating with the addition of organic fibers, for example, linen, as reinforcing elements, starch in an amount of 5-7% by volume as a bonding component and clay in coli 15-20% by volume as an astringent and water-retaining component. All components are thoroughly mixed in a dry form and shut with water at the rate of 150-170 liters per m ^{3 of} dry mix, mixed again and distributed in a fluid consistency to a drop method. Then the nutrient layer with seeds is dried to a state of semi-solid consistency, the fabric rolls into a roll, is transported to the place of laying, spreads out on the landscaping site and is fixed on the ground using pegs inserted in loops 5 of tape 3.

Example. Grass cover is made of gauze, reinforced with braid. As a composition for the nutrient mixture was taken milled peat with the addition of complex mineral fertilizer containing nitrogen, phosphorus, potassium, in the amount of 0.8-1.2 kg per 1 m ^{3 of} peat. The application rate of plant seeds was 10-35 g / m ² coverage. Organic fibers (linen) were added as reinforcing elements and starch in an amount of 5-7% by volume as an adhesive component. Clay as an astringent and water-retaining component was added in an amount of 15-20% by volume. The “islands” were made with a diameter of 12-15 mm and a thickness of 4-5 mm. After spreading on the slope of the coastal ledge in the city of Svetlogorsk, Kaliningrad Region, the grass cover was fixed with wooden pegs and sprinkled with a layer of sand 5-7 mm. Grass seeds gave friendly shoots.

It is due to the fact that the fabric layer is made of cotton fabric with a rare interweaving of threads and is reinforced with longitudinal and transverse ribbons with loops at the edges of the canvas, and the layer of nutrient mixture with seeds is located in the form of separate “islands” containing reinforcing, adhesive and moisture-retaining components , reduces the consumption of fabric and simplifies the technology of manufacturing grass cover.
