RU2551561C1 - Method of treatment of substrate with root layer of culture lawn for its renovation - Google Patents

Abstract

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.

EFFECT: method enables to increase the intensity and to reduce the time of formation of a strong root system of grass lawn cover, to reduce the recovery times of the lawns.

Description

The invention relates to the field of agriculture and urban economy and can be used for processing a substrate with a root layer of cultivated lawn for its renovation to quickly create high-quality lawns for various purposes: sports fields, golf courses, racecourses, grass cover for playgrounds, ground floor, Moorish and for lawn repair.

A known method of creating grassy lawn cover for outdoor sports grounds and care for it according to patent RU 2087614 of 11.22.95, including sowing the prepared area with grass seeds, daily two-time watering, mowing with periodic fertilizing and repairing the area after each use. Repair consists in raking and adding soil repair mixture containing grass seeds and consisting of the following components, wt.%: Chernozem - 60-80, peat - 35-10, dry coniferous sawdust - 5-10.

The disadvantage of this method is the complexity of lawn care during its cultivation and a sufficiently long period of formation of grass cover.

A known method of accelerating the growth and restoration of the lawn according to the application RU 2432736 from 10.11.2011, according to which the surface of the lawn is at least partially covered from above with an open bottom room, into which CO ₂ is supplied, and the surface of the lawn closed by the room is illuminated using lighting means.

The method is quite expensive.

There are various methods of creating lawns from lawn elements, previously cultivated before laying them on a greened plot (RU 2234207 from 13.11.99, 2097961 from 10.12.97, etc.).

These methods also have high costs for creating lawns.

There is also known a method of creating grass cover from lawn strips grown hydroponically on a vermiculite substrate according to patent RU 2393665 dated July 13, 2007. VIPON vermiculite substrate with a pH level of 6.5-7.2 and granules up to 2 mm is poured into a container with a layer of 1 cm , saturate with a liquid nutrient medium of 0.1% concentration, a mixture of lawn grass seeds is sown on the surface of the substrate, they are covered with a layer of 0.3-0.5 cm of the substrate and covered with a polymer film. As a container, a waterproof plastic film can be used. When growing a lawn in open ground, a plastic film is spread on a prepared area, bent it in any way at the edges, forming a container with a bottom and side walls. For lawn repair use the cultivation of a lawn rug in this way with those grass seeds that are present in the grass stand requiring repair. The disadvantages of this method are the complexity of the composition of the applied mineral fertilizers, the use of only finely fractionated vermiculite with granules up to 2 mm and a layer from 1.3 to 1.5 cm, which increases the cost of the method.

The claimed method, as well as known, includes the repair of lawns.

However, the prior art has not revealed methods for renovating a cultivated lawn by treating a substrate with a root layer.

The objective of the claimed method is the creation of technology for the renovation of high-quality lawns for a wide range of purposes of partner, sports, Moorish, grass coverings for playgrounds by treating the substrate with a root layer of lawns.

The technical result consists in increasing the intensity and reducing the time of formation of a strong root system of grassy turf and increasing its performance, which reduces the cost of its maintenance and costly repairs. The method is simple to execute. It is used even in adverse climatic conditions. The main advantage of this method is the reduction in the terms of restoration of lawns.

To achieve the specified technical result, the method of processing the substrate with a root-inhabited layer of cultivated lawn for its renovation is characterized by the fact that the upper grassy layer of the lawn with organic material is mechanically removed, a 10% hydrogen peroxide solution is introduced into the remaining substrate with the root system and organic material in 4 stages irrigation irrigation, and the first irrigation is carried out at the rate of 20 tons of solution per 0.8 ha, the mass of organic material swollen to the surface is removed, then suschestvlyayut next three watering for two days as the appearance of dark spots of organic material on the sand on the surface to obtain a substrate sand no pure organic material. Two washing irrigation is carried out, sand is added and seeds of sod-forming cereals are sown on it.

The invention is illustrated by the following example.

Example. To renovate and quickly create high-quality lawns for various purposes: ground, sports, Moorish, grass cover for playgrounds and for lawn repair, the following actions are carried out. First, the upper grassy layer of the lawn with organic material is mechanically removed to sand. Then, a 10% hydrogen peroxide solution is introduced into the remaining after removal of the upper layer with the root system and organic material by a 4-stage irrigation irrigation. The first watering is carried out at the rate of 20 tons of solution per 0.8 ha. The mass of organic material swollen to the surface is removed mechanically. Then, the next three waterings are carried out for two days as dark spots of organic material appear on the sand until pure sand without organic material is obtained on the surface of the substrate. Two washing irrigation is carried out, sand is added and seeds of sod-forming cereals are sown on it.

Studies and a series of laboratory experiments were conducted to accelerate the formation of lawns for various purposes: ground, sports, Moorish, grass cover for playgrounds and for lawn repair.

Studies and experiments have shown that the claimed method allows to optimize the process of germination of seeds of cereal perennial grasses, with the help of which the seeds of plants are brought to the “hatching” stage in just 3 days, provides the main advantage of this method - the possibility of a significant reduction in time (up to 16-20 days) on the creation or repair (restoration) of the vegetation cover of the lawn.

Thus, the claimed method allows to increase the growth rate and reduce the formation time of a strong root system of grassy turf, increase its performance, which reduces the cost of its maintenance and expensive repairs. The method is simple to implement, applicable even in adverse climatic conditions of the Far North and can significantly accelerate and reduce the cost of creating high-quality grass-turf lawn cover, plan ahead for the timing, density of the future grass stand and the type of created phytocenosis. The main advantage of this method is the reduction in the terms of restoration of lawns.
