The invention relates to agriculture, in particular to methods for forming a combined turf surface used for sports purposes, in particular on a football field.

An artificial turf is known, in particular for artificial turf of a sports field, containing an artificial mat made of a carrier to which fibers of the artificial grass type are attached, characterized in that the carrier is provided at least partially with at least one additional material -component, increasing in volume and constantly maintaining an increased volume in the said part of the carrier under the influence of external stimulating influences after its introduction into the artificial mat. The additional material component is evenly distributed in the carrier. The additional material component is included in the carrier in the form of a thread. The additional component material is included in the carrier in the form of at least one layer. The carrier is provided with another additional component material included in the carrier as a second layer. The layer of additional material component and the layer of another additional material component are separated from each other by an intermediate layer. At least the first group of fibers for sports purposes such as artificial grass is provided with at least one of the additional component materials. The additional material component is uniformly distributed in the artificial grass fiber. Sports fiber like artificial grass is an extruded fiber. Sports fiber such as artificial grass is a crosslinked fiber. The additional material component is foam. The foam material consists of a mixture consisting of one or more polymeric materials combined with at least one chemical foaming material compatible with said mixture. The foam has a closed cell structure after expansion. The additional material component expands and permanently retains the increased volume on at least a portion of the support under the influence of heat. The carrier is made of crosslinked materials. The artificial grass type fibers of the first group are located between the artificial grass type fibers of the second group. Fibers for sports purposes such as artificial grass of the first group are located between the fibers of the artificial grass type of the third group. An artificial mat for use in artificial turf, comprising a carrier to which artificial grass fibers according to any one of the preceding claims are attached. (Patent of the Russian Federation No. 2446243, published on March 27, 2012).

For the prototype, a method of cultivating grass cover is chosen, including the following stages: a) sowing seeds of natural turf on a fertile layer of soil located on a base that supports fibers of artificial turf, and on an essentially elastic permeable layer, which is made in the form of a three-dimensional network, where the specified elastic the membrane defines a layer having a thickness, in side view of the system, of 0.005 m to 0.020 m; b) growing natural turf to a height equal to or greater than the length of artificial turf fibers; wherein the roots of said natural turf are capable of penetrating the backing supporting the fibers of the artificial turf and penetrating the elastic membrane to reach the vegetative layer below; c) trimming natural turf plants to maintain the desired height of said natural turf, which is at least the same as the length of artificial turf fibers, in particular maintaining the height of natural turf in the range from 0.015 m (15 mm) to 0.040 m (40 mm), in depending on the intended use of the specified surface. At stage a) the sowing of seeds is carried out in a fertile layer of soil with a thickness of 0.005 m (5 mm) to 0.025 m (25 mm), separated from the elastic membrane by a permeable cloth (geotextile), which prevents the ingress of soil particles; where the roots of natural turf are able to penetrate through the aforementioned permeable web with penetration through the membrane, while the specified membrane remains free from soil particles. The method of cultivation includes the stage of harvesting and cleaning the above-mentioned fertile soil layer without loosening. (Patent of the Russian Federation No. 2627055, published on 08/03/2017).

The common disadvantages of the known technical solutions include the formation of grassy lawns directly on the object and the impossibility of transportation to a given object.

The task is to create a rolled combined grass cover

EFFECT: formation of a combined grass lawn covering with a stabilizing artificial base that protects the root system of a natural herbage, the possibility of easy installation on site and its operation 2-3 days after laying.

The technical result is achieved by a method for forming a rolled combined grass cover, including sowing seeds of natural turf on a layer of soil located on a base supporting artificial turf fibers, growing natural turf to a height corresponding to or exceeding the length of artificial turf fibers, where the roots of said natural turf are able to penetrate through base, trimming natural turf plants to maintain the desired height of said natural turf, which is at least the same as the length of the artificial turf fibers, while the artificial turf is laid on a pre-leveled sandy soil and stitched together, quartz is evenly laid on the artificial turf base with the first layer sand grade MDF2 with a fraction size of 0.1-0.4 mm at the rate of 20 kg / m ² , a mixture of quarry sifted sand 77 kg / m ² , natural zeolite 0.4 kg / m ² with a fraction size of 0 .2-1.2 mm and g hydrogel 0.5 kg / m ² , the second layer is introduced with starting doses of complex fertilizer YaraMila NPK 7-20-28 at the rate of 25 g / m ² and a soil conditioner based on the mineral-silicate complex with a colloidal function Agrosil LR at the rate of 150 g / m ² , carry out irrigation by sprinkling 5-7 l / m ² , sow with a mixture of perennial herbs perennial ryegrass Vesuvius perennial, perennial ryegrass Lifrance, bluegrass meadow Limousine, bluegrass meadow Lincolnshire, red hairy fescue Jevelyn, red fescue modified Livista at their respective ratio of 1: 1:1:1:0.5:0.5, for nine months, watering is carried out to maintain field moisture capacity within 70-80% and natural turf plants are trimmed to the length of artificial turf fibers, cutting is carried out in rolls 1.2 m wide , 15 m long and 0.03 m thick.

Quartz sand MDF2 is a natural mineral characterized by its high content of silicon oxide and a very small amount of soluble calcium compounds, as well as iron and manganese. Fractional and chemical composition with a high degree of dispersion. Silicon oxide - 91%. Other impurities 0.2-0.5%. The content of the clay component is 0.5%, the average particle size is 0.1-0.315 microns. The use of quartz sand is due to the creation of surface characteristics, such as uniformity and evenness, to increase the hardness of the playing surface. The size of fractions of 0.1-0.4 mm is the most optimal, because. bulk density and fillability of artificial membranes is 100%. The consumption rate of 20 kg/m ^{2 is} sufficient and necessary to fill the membranes of the artificial base.

Laying a uniform second layer of a mixture of quarry screened sand, natural zeolite and hydrogel ensures the retention of moisture and nutrients when growing natural turf. The size of fractions of 0.2-1.2 mm of sifted sand and natural zeolite ensures that the nutrient mixture is retained by the second layer on quartz sand.

YaraMila NPK 7-20-28 is a complex granular fertilizer for basic dressing and top dressing of various crops. Each granule contains all the macro and microelements necessary for the plant in the correct ratio and in a form accessible to plants. Phosphorus, which is part of the YaraMila NPK 7-20-28 fertilizer, is completely soluble in water. It has a balanced content of nitrate and ammonia nitrogen. YaraMila NPK 7-20-28 granules are particularly durable and, compared to other fertilizers, are less prone to breaking and dusting during storage or application. In addition to strength, the granules are of the same size, which has a positive effect on the accuracy and accuracy of their application. This reduces fertilizer losses. The consumption rate of 25 g/m ² is a sufficient and necessary amount to obtain a root-inhabited layer, which ensures the quality of the strength characteristics.

Soil conditioner based on a mineral-silicate complex with a colloidal function Agrosil LR is an electrolyte system consisting of partially dehydrated sodium silicate and phosphate. As an amorphous silicate with a large specific surface, "Agrozil LR" transfers its surface activity to the environment. Promotes soil improvement, regeneration of grass cover, development of a healthy root system, conservation of nutrient reserves in the soil, improvement of lawn density, color and wear resistance. The consumption rate of 150 g/m ² is sufficient and necessary to obtain a full-fledged root system.

Irrigation by sprinkling with a consumption rate of 5-7 l / m ² provides 100% wetting of two layers, and hence 100% seed germination.

Herbs should be resistant to diseases, the greatest preference is when there are at least 5 varieties in the mixture, this is due to the prevention of diseases. Under unfavorable conditions, only the development of one variety worsens, which allows you to exploit the lawn and fight diseases in parallel.

The claimed mixture of herbs is characterized as stable and unpretentious to care. Its quantitative and qualitative composition provides a dense herbage with high strength characteristics.

Perennial ryegrass is a fast growing perennial plant. Under the snow goes green. The plant tolerates moderate shade, trampling and compaction after mechanical damage. Sensitive to frost.

Bluegrass meadow - has a fairly fast growth and high aggressiveness of the root system. Differs in considerable durability, it is not exacting to climatic conditions, shade-tolerant and drought-resistant.

Red fescue is less winter-hardy and frost-resistant, more drought-resistant and shade-tolerant than meadow grass, resistant to fungal diseases.

The formation of a natural grass cover is carried out within nine months, during which the underground and ground parts have time to form, for which all this time the field moisture capacity threshold is maintained within 70-80% and the natural turf plants are trimmed to the length of the artificial turf fibers,

Rolls with a width of 1.2 m, a length of 15 m and a thickness of 0.03 m are the most versatile for their loading, transportation and installation.

An example of a specific implementation.

The coating, for example, a playmaster, was laid on a previously leveled sandy soil measuring 100 m × 100 m and stitched together, for example, with IPCAFIL2200M WHITE / BLACK threads (1 BOX / 10 COILS). On the artificial base, the first layer was evenly laid quartz sand brand MDF2 with a fraction size of 0.1-0.4 mm at the rate of 20 kg/m ² . The cells of the artificial base were completely covered with sand. The second layer was uniformly applied with a mixture of quarry screened sand 77 kg/m ² , natural zeolite 0.4 kg/m ² with a fraction size of 0.2-1.2 mm and hydrogel 0.5 kg/m ² . Received a uniform and even surface. Starting doses of complex fertilizer YaraMila NPK 7-20-28 at the rate of 25 g/m ² and soil conditioner based on the mineral-silicate complex with colloidal function Agrosil LR at the rate of 150 g/m ² were added to the second layer. Irrigation is carried out by sprinkling 5-7 l / m ² . A mixture of perennial ryegrass Vesuvius, perennial ryegrass Lifrance, meadow grass Limousine, bluegrass Lincolnshire, red hairy fescue Jevelyn, red modified Livista fescue was sown, respectively, at a ratio of 1:1:1:1:0.5:0.5. In the next nine months, sprinkler irrigation was carried out to maintain field capacity within 70-80% and the natural turf plants were trimmed to the length of the artificial turf fibers.

The combined lawn was cut with a specialized BigTick®1040 harvester in rolls 1.2 m wide, 15 m long and 0.03 m thick. After the installation of the lawn combined coating, operation was possible in 2-3 days.

Thus, the claimed method provides the formation of a combined grass lawn with a stabilizing artificial base that protects the root system of natural herbage, the possibility of easy installation on site and its operation 2-3 days after laying.
