Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
The invention relates to a soilless sod taking fabric and silicate mineral as lining materials, which sequentially comprises a substrate layer, a cushion layer, a substrate layer and a straw stem layer from bottom to top; the liner layer comprises dustproof cloth or geotextile; the matrix layer comprises silicate mineral particles and organic fertilizer.
The substrate layer is a substrate which is laid on a flat land and has the thickness of not less than 2cm and can protect surface soil, the function is that the original plough layer of the soil is not damaged when the full-lawn turf is transplanted, and any material which does not harm the growth of plants and can be cultivated can be adopted.
The cushion layer has the functions of improving the tensile resistance of the turf, enabling the turf not to be broken easily and shortening the period of outplanting; the liner layer is made of environment-friendly polyester dustproof cloth.
The matrix layer is used for providing nutrient substances for the healthy growth of turfgrass, the formula is that the volume ratio of silicate mineral particles to organic fertilizer is 90:10, the particle size of the silicate mineral particles is 3mm, the silicate mineral particles are soil-like particles formed by hydrothermal alteration or weathering of silicate ores, the silicate mineral particles are rich in calcium, magnesium and other nutrient elements, the water and fertilizer retention performance is good, and the specific gravity is 120kg/m3(ii) a The organic fertilizer adopts finished product complete fertilizer sold in the market; the Chinese herbal stem in the grass stem layer is specially used for the rhizome and stolon of the lawn grass which can be propagated asexually.
The preparation method of the soilless sod comprises the following steps:
step 1, paving a base layer material on roughly leveled farmland soil, finely leveling the soil after paving, repeatedly pressing the soil, and finishing the soil to be as flat as a mirror surface;
and 2, paving lining layer environment-friendly polyester dustproof cloth or felt type moisturizing geotextile on the basis of the step 1.
And 3, paving the fully mixed matrix layer material with the thickness of 2cm on the basis of the step 2, rolling once, watering and moisturizing.
And 4, paving grass stems on the basis of the step 3, wherein the propagation coefficient is 1:10, and watering is carried out while paving the grass stems so as to prevent the dehydration of the grass stems from influencing the survival rate.
And 6, after the step 5 is finished, entering a daily maintenance management program, and taking out the lawn grass from the nursery for sale when the lawn grass grows to 90% coverage.
And (3) experimental design: the invention adopts random block design, treats the soilless sod which is produced by the preparation method and takes the fabric and the silicate mineral as the substrate, and the contrast sod is the sand sod used by the traditional production mode, and the area of the cell is 30m multiplied by 2m for 3 times. The grass seeds adopt the hybrid bermudagrass widely applied in the market.
The dust cloth soilless sod test result: as shown in fig. 1 to 4, the grass coverage and stem density of the lawn were observed at 10, 20, 30 and 40 days after sowing, the chlorophyll content and the turf torsion (traction) were observed at 30 days after sowing, and the grass weed count was counted at 40 days after sowing, wherein BB represents a soilless turf of the present invention using dust cloth and silicate mineral particles as a backing and a matrix; CK stands for traditional sandgrass turf and results show: the lawn grass coverage, stem density and grass torsional force (traction) of the soilless sod taking the fabric and the silicate mineral as the matrix are all obviously higher than that of a control sod (CK), and the weed quantity is obviously lower than that of the control sod (CK); the fact that the horizontal expansion rate of the stolons is measured by adopting the special drilling device for golf greens shows that the stolons of the soilless turf taking the fabric and the silicate minerals as the linings need to grow for 14 days when full and empty ground is full, and the stolons of the soilless turf taking the fabric and the silicate minerals as the linings need to grow for 19 days when full and empty ground is contrasted, and the expansion rate of the stolons of the soilless turf taking the fabric and the silicate minerals as the linings is obviously higher than that of the contrasted turf.
