FIELD: agriculture.

SUBSTANCE: in the method the mechanical removal of the top grass layer of a lawn with the organic material to the sand is performed, 10% hydrogen peroxide solution is applied in the remaining substrate with the root system and the organic material by the 4-step sprinkler irrigation. And the first irrigation is carried out at the rate of 20 tons of hydrogen peroxide solution per 0.8 hectares. The mass of the organic material exfoliated on the surface is removed, then the next three irrigations are performed within two days, as the appearance of dark spots of organic material on sand, to obtain on the substrate surface of clean sand without the organic material. Two washing irrigations are carried out, and sand is poured for subsequent sowing seeds of sod-forming grasses in it.

The invention relates to the field of rural and urban, and can be used for processing the substrate with the root-inhabited layer of cultural turf for its renovation to quickly create high-quality lawns for various purposes: sports fields, Golf courses, race tracks, turf for playgrounds, ground floor, Moorish and repair lawns.

Known method of creating herbal grass cover outdoor sports grounds and care for them according to the patent RU 2087614 from 22.11.95, including seeding sites are prepared grass seeds, half daily watering, mowing with periodic fertilization and repair of the grounds after each use. The repair is to grabline and the subsequent maintenance of soil mix containing grass seed and consisting of the following components, wt.%: Chernozem - 60-80, peat - 35-10, dry pine sawdust - 5-10.

The disadvantage of this method is the complexity of lawn care during its cultivation and long enough for the formation of the herbage.

The known method of accelerating the growth and repair of lawn on request EN 2432736 from 10.11.2011, according to which the surface of the lawn at least partially close the top room with open bottom, which serves CO2and the surface of the lawn, Zach�ytou room, lights using lighting.

The method is quite expensive.

There are different ways to create a lawn from grass seed items, pre-cultivated before stacking on the green area (EN 2234207 from 13.11.99, 2097961 from 10.12.97, etc.).

These methods also have high costs for the establishment of lawns.

Also known a method of establishing turf from grass strips, grown hydroponic method on vermiculite substrate according to the patent RU 2393665 from 13.07.2007 G. Vermiculite substrate WEAPON with a pH of 6.5 to 7.2 and granules up to 2 mm is poured into the container with a layer of 1 cm, nourish liquid nutrient medium with 0.1% concentration, on the surface of the substrate sow a mixture of grass seed, cover them with a layer of 0.3-0.5 cm of the substrate and covered with plastic film. As the container can be used waterproof plastic film. When growing a lawn in the open ground on the prepared ground spread plastic wrap, tuck her in any way at the edges, forming a container with a bottom and side walls. To repair lawns growing use of turf grass Mat according to the method, with the seeds of grasses that are present in the stand, requiring repair. The disadvantages of this method are the complexity of the applied mineral fertilizers, the use�R only melkomasshtabnogo with vermiculite granules up to 2 mm and a layer of from 1.3 to 1.5 cm, that increases the cost method.

The inventive method, as is known, includes the repair of lawns.

However, the prior art is not identified the ways cultural renovation of the lawn by treating the substrate with root-inhabited layer.

The objective of the claimed method is the creation of the technology renovation of high-quality lawns wide range of destination, ground, sports, Moorish, turf for playgrounds by processing the substrate with the root-inhabited layer of lawns.

The technical result is to increase the intensity and reduce the time of the formation of a strong root system herbal grass coverage and improve its performance, which reduces the cost of its maintenance and expensive repairs. The method is simple in execution. Applies even in adverse climatic conditions. The main advantage of this method is the reduction of time of restoration of lawns.

To achieve the specified technical result is a method of processing a substrate with root-inhabited layer of cultural turf for its renovation is characterized in that it is performed by mechanical removal of the upper herbaceous layer of lawn with an organic material is introduced into the remaining substrate with the root system and organic material 10% solution of hydrogen peroxide by 4 - this�tion sprinkler irrigation, the first watering is carried out at the rate of 20 t of a solution of 0.8 hectares, remove exfoliated on the surface of the mass of organic material, then carry out the following three irrigation within two days as the appearance of dark spots organic material in the sand to obtain on the surface of the substrate of clean sand without organic material. Carried out by two washing watering, pour the sand and sown in him the seeds of turf grasses.

The invention is illustrated by the following example.

Example. For renovation and quickly create high-quality lawns for various purposes: ground floor, sports, Moorish, turf for playgrounds and for repair of lawns perform the following steps. First mechanically remove the upper herbaceous layer of lawn with an organic material to sand. Then bring in the remaining after the removal of the top layer with the root system and organic material substrate 10% solution of hydrogen peroxide by 4-stage sprinkler irrigation. The first watering is carried out at the rate of 20 t of a solution of 0.8 ha. Expanded on the surface of the organic material is removed mechanically. Then carry out the following three irrigation within two days as the appearance of dark spots organic material in the sand to obtain on the surface of subs�rata pure sand without organic material. Carried out by two washing watering, pour the sand and sown in him the seeds of turf grasses.

Studies have been conducted and a series of laboratory experiments to accelerate the formation of lawns for various purposes: ground floor, sports, Moorish, turf for playgrounds and for repairing lawns.

Research and experiments have shown that the inventive method allows to optimize the process of germination of cereal seeds perennial herbs, with which plant seeds in just 3 days brought to the stage "polynesias", provides the main advantage of this method is the possibility of significant reduction of time (up to 16-20 days) to create or repair (restoration) of vegetation in the lawn.

Thus, the claimed method allows to increase the intensity of growth and reduction of time of formation of a strong root system herbal grass coverage, increase its performance and reduce costs for its maintenance and expensive repairs. The method is simple to implement, is applicable even in adverse climatic conditions of the far North and can significantly speed up and reduce the cost of creating high-quality grass-turf grass coverage in advance to plan the timing of receipt, the density of the future of grass and type of create�Wai of kulturpflanze. The main advantage of this method is the reduction of time of restoration of lawns.

A method of processing a substrate with root-inhabited layer of cultural turf for its renovation, which is performed by mechanical removal of the upper herbaceous layer of lawn with an organic material to sand, make the rest of the substrate with the root system and organic material 10% solution of hydrogen peroxide by 4-stage sprinkler irrigation, the first watering is carried out at the rate of 20 tons of hydrogen peroxide solution of 0.8 hectares, remove exfoliated on the surface of the mass of organic material, then carry out the following three irrigation within two days as the appearance of dark spots organic material in the sand to obtain on the surface of the substrate of clean sand without organic material is carried out by two flushing irrigation and spiked sand for subsequent sowing of seed turf grasses.
