FIG. 1 is a schematic view of the construction of a lawn roll of the present invention;

the parts in the drawings are numbered as follows: 1. the soil-covering layer comprises a mixed matrix layer, 2 a mesh fabric layer, 3 and a plain soil layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a method for rapidly rolling a lawn is provided, which includes the steps of:

(1) site preparation

(a) Soil preparation

Firstly, selecting a field with flat terrain, convenient irrigation and smooth drainage, then, flooding the selected field once in advance for 15 days, carrying out rotary tillage after airing for 10 days, requiring the diameter of soil particles in the field to be not more than 1cm after rotary tillage, uniformly spreading 2500 plus materials of decomposed organic fertilizer and 3000 kilograms per mu of field, leveling the field into a flat ridge with the depth of 1.2 x 30 m, arranging drainage ditches with the width of 30cm at the periphery, and after the flat ridge is made, using an iron compactor (30 kg) to press the flat ridge for the first time to level the surface and achieve a certain soil moisture preservation effect.

(b) Lapping

And (5) paving a net on the flat bed. The net laying can increase the tensile resistance of the lawn roll, the root injury is less during transplanting, the recovery is fast, the early outplanting is facilitated, the net laying material is degradable non-woven fabric of 80 g/square meter, the thickness is too thick and waterproof, the lawn is easy to tear when the lawn is uncovered too thin, the non-woven fabric can be cut into square blocks of 30cm and 60cm according to requirements, then the square blocks are tiled on the prepared ridge surface, the second time of pressing is carried out after the net laying, the watering is carried out after the pressing is finished, and the first time of watering is carried out.

(c) Preparation of matrix soil

Mixing garden soil and decomposed organic fertilizer according to the proportion of 4: 1 to prepare the matrix soil, and sieving the matrix soil once.

(2) Seed selection and sowing

Grass seeds with expansive rhizomes or stolons are generally selected, such as bermuda grass, meadow bluegrass, tall fescue, ryegrass and the like. The seeding rate is slightly larger than that of a direct-seeded lawn, the lawn is annual bluegrass 40 g/square meter, and the ryegrass, tall fescue and bermuda grass 30-40 g/square meter. In the production process, a mixed sowing mode is commonly used, wherein bermuda grass and ryegrass are mixed according to the mass ratio of 1: 3, or the ratio of tall fescue, ryegrass and bluegrass in a mass ratio of 2: 7: 1, and sowing in a mixing way.

When in sowing, grass seeds are mixed according to the mass ratio of 1: 3, uniformly mixing the mixture with the prepared matrix soil, uniformly sowing according to the shape of the Chinese character 'hui', covering the matrix soil prepared in advance after the sowing is finished, wherein the thickness is not more than 1cm, compacting for the third time by using a compactor to ensure that the non-woven fabric, the grass seeds and the matrix soil are tightly contacted, and sprinkling water for the second time after the compacting is finished.

(3) Water spray

Spraying water every day after sowing, wherein the water is required to be adjusted into mist during water spraying and cannot be directly flushed with a seedbed, when the temperature condition is appropriate, the seedlings can emerge in 4-6 days generally, and when more than 70% of the grass emerges, normal management can be carried out.

(4) Lawn management

(a) Moisture management

And (4) according to soil and weather conditions, filling water for 1 time every 4-5 days. Irrigating for 1 time 2-3 days before outplanting to prevent soil from being too loose.

(b) Fertilizing

The turf is produced by using nutrient soil, so that the turf grass is generally free from fertilizer shortage in the initial stage, and if the fertilizer shortage phenomenon occurs, urea with the mass fraction of 0.2% or potassium dihydrogen phosphate solution with the mass fraction of 0.2% can be sprayed.

(5) Lawn rolling up device

After 40 days of growth, when the grass grows to 5-6cm, the lawn can be rolled for outplanting. Watering for 1 time 2-3 days before peeling, rolling the turf together with the mesh belt, and stacking the turf into a pile for convenient transportation. The turf transplantation is preferably carried out at any time, water is reserved in the transportation process by attention, the turf transplantation and the net cloth are paved in a lawn planting area together during paving, then the turf transplantation is compacted once by a compactor, and then the turf transplantation is finished by watering.

The invention has the beneficial effects that:

firstly, the method for rapidly coiling the lawn can shorten the production period of the lawn coil to 40 days, and 5-6 stubbles can be produced in one year;

secondly, the method for rapidly rolling the lawn can realize rapid molding of the lawn roll, ensure the quality of the lawn roll, reduce the input cost of the lawn roll and damage to a soil plough layer, and is popular with manufacturers.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
