The technical result is achieved according to the first embodiment in that the anti-erosion coating contains two layers of biodegradable non-woven base, between which is placed a reinforcing synthetic mesh of non-degradable material and a layer of grass mixture seeds, which contains seeds coated with a coating of fertilizers and minerals, while the biodegradable non-woven base is made from flax fiber or from jute fiber. The technical result is achieved according to the second embodiment in that the coating contains two layers of biodegradable non-woven base, between which there is a layer of seeds of the grass mixture, which contains seeds coated with a coating of fertilizers and minerals, while the biodegradable non-woven base is made of flax fiber or jute fiber. 2 ill.

Description

The coating is intended for the protection of soil embankments and slopes, soil deboning of pipelines of ground laying, surfaces of soil of backfill of pipelines of underground laying, quarries, etc.).

Known grass coating, consisting of separate layers bonded to each other, including a layer of woven material, a lawn layer with plant material and an upper protective layer, while the layer of woven material is reinforced with synthetic thread, the layers are bonded by the formed root system of plant material, the shoots of which are formed grass coating layer (RU 18871 U1, 08/10/2001).

The disadvantage of this coating is the lack of nutrients necessary for the growth and development of plants, as a result of which seed germination is reduced, the development of the root system of plants is delayed, which generally degrades the quality of the grass coating.

The objective of the utility model is to expand the arsenal of technical means - grass coverings.

The technical result of the proposal is the strengthening and protection of soil surfaces, increasing the germination of seeds. The coating makes it possible to ensure the creation of a uniform vegetation cover on the soil in a short time with the formation of a powerful root system and is highly reliable in relation to the rapid emergence, growth and development of plants.

The technical result is achieved according to the first embodiment in that the anti-erosion coating contains two layers of biodegradable non-woven base, between which is placed a reinforcing synthetic mesh of non-degradable material and a layer of grass mixture seeds, which contains seeds coated with a coating of fertilizers and minerals, while the biodegradable non-woven base is made from flax fiber or from jute fiber, and the mixture of seeds includes festulolium seeds.

The technical result is achieved according to the second embodiment in that the coating contains two layers of biodegradable non-woven base, between which there is a layer of seeds of the grass mixture, which contains seeds coated with a coating of fertilizers and minerals, while the biodegradable non-woven base is made of flax fiber or jute fiber, and the mixture of herbs includes festulolium seeds.

Figure 1 presents the coating according to the first embodiment.

Figure 2 presents the coating according to the second embodiment.

The coating according to the first embodiment contains layer 1 — non-woven biodegradable fabric, synthetic mesh 2 and seeds 3 of the special grass mixture TC Ecotrassa, layer 4.

The coating provides grass stand development on soils with a humus content of 1% or more:

- within 1-2 years, the coating should form a uniform grass stand with an abundant root system, which, penetrating deep into the soil, binds the soil and forms a turf with high mechanical strength, both horizontally and vertically;

- field germination of grass mixtures should be calculated by the formula:

where S is the number of sprouts per 1 m ² ;

0.4 - coefficient taking into account the probability of seed germination;

n ₁ is the concentration of seeds;

w _i - weight of 1000 seeds, g / 1000 pcs;

i is the number.

- after 20 days from the day of sowing, in accordance with the operating instructions and at an ambient temperature of plus 5 ° C to plus 25 ° C, a herbage should be formed, the field germination of which when using the TC-K Ecotrass grass mixture must be at least 3000 sprouts per 1 m ² ; when using TS-UK Ekotrassa grass mixtures - at least 4000 shoots per 1 m ² .

By the time of formation of the stand with an abundant root system (1-2 years), the biodegradable coating web should decompose.

The coating is intended for slopes whose slope angle from a horizontal surface exceeds 10 °.

According to the second variant, the coating contains layer 1 - non-woven biodegradable fabric, seeds 2 of a special grass mixture TC Ecotrassa, layer 3.

The coating provides grass stand development on soils with a humus content of 1% or more:

- within 1-2 years, the coating should form a uniform grass stand with an abundant root system, which, penetrating deep into the soil, binds the soil and forms a turf with high mechanical strength, both horizontally and vertically;

- field germination of grass mixtures should be calculated by the formula:

where S is the number of sprouts per 1 m ² ;

0.4 - coefficient taking into account the probability of seed germination;

n _i is the concentration of seeds;

w _i - weight of 1000 seeds, g / 1000 pcs;

i is the number.

- after 20 days from the day of sowing, in accordance with the operating instructions and at an ambient temperature of plus 5 ° C to plus 25 ° C, a herbage should be formed, the field germination of which when using the TC-K Ecotrass grass mixture must be at least 3000 sprouts per 1 m ² ; when using TS-UK Ekotrassa grass mixtures - at least 4000 shoots per 1 m ² .

- by the time of formation of a stand with an abundant root system (1-2 years), the biodegradable coating web should decompose.

The herbal mixture includes festulolium seeds - a hybrid obtained by hybridization of various types of annual and perennial plants. Such a culture combines high resistance to adverse external conditions, high growth rate, longevity, high winter hardiness, survivability, drought tolerance. Festulolium grows well both in single-species sowing and in the composition of grass mixtures. Festulolium forms tall grass stands and forms a closed grass stand, able to create a high density of plants per unit area. Therefore, festulolium is the most important sludge former when creating slopes, lawns, and for land reclamation.

The coating (according to the second option) is intended to restore the vegetation cover and strengthen the soil surfaces, the slope of which from the horizontal surface does not exceed 10 °.

Coating for options is intended for all climatic regions of the Russian Federation and any soil types with a humus content of 1% or more.
