Background technology

Green grassland is to protection and beautify the living environment, maintaining ecological balance plays an important role.In 20 end of the centurys, lawn soilless comes out, and it has overcome traditional existing many shortcomings of native turf that have effectively.In recent years, the technical development relevant with lawn soilless is very fast, existing Chinese patent is as No. 98204959.5 " a kind of combined type grass blanket of soilless culture ", No. 01256576.8, number 00209886.5 " Vegetation net growing sod " " carpet turf ", number 01108799.4 " production method of lawn soilless ", number 01274098.5 " environment-protective type plant cover plantation blanket ", No. 02221432.1 " lawn soilless inoculating bed " etc.Though these lawns have save land resources, cultivation easily, advantage such as convenient transportation, but but expose the shortcoming of the existence foundation is weak on lawn itself: the weak effect of preserve moisture and fertility, water-fertilizer nutrient is met hot pressurized and can be overflowed, and liquid manure runs off waste greatly, and effective rate of utilization is low.If reasons such as, can't adhere to often water fertilisings special owing to topography and geomorphology, grass planting is easy to wither.Trace it to its cause, original lawn exists structural defective.

Summary of the invention

The purpose of this utility model just is to provide a kind of shortcoming that can overcome original lawn soilless, the place of not selecting to grow, the drought-resistant thick matrix lawn soilless of multi-layer combined type.

The thick matrix lawn soilless of the multi-layer combined type that the utility model provides is made up of greenweed layer, the covering bed of material, sowing fibrage, vegetation soil layer, liner fibrage and separation layer.

The grass that the greenweed layer is promptly cultivated.

The covering bed of material is by through being ground into trifle or granular agricultural wastes, adds flyash and organic sludge compost and mixes composition, and its thickness is 10～50mm.Covering is the soil moisture conservation measure of very effectively economizing on water; the effect of the covering bed of material is exactly to alleviate rainwater or water to the erosion of waste material and earth; reduce the water evaporates loss, not premature decomposition, the degeneration of absorbent polymer material in the protection vegetation soil layer prolongs its service life.

Sowing fibrage and liner fibrage are organic substrate, form as discarded cotton, fiber crops, hair, silk, chemical fibre leftover pieces fiber or discarded animal and plant fiber mixing by trade waste, in animal and plant fiber account for total amount 70%～80%, the useless fiber of industry 30%～20% the ratio that accounts for total amount mixes, be machined to velvet-like thing through blooming, be processed into the composite fibre tilting blanket with certain intensity, water-permeable and air permeable through needing machine again, its thickness is 10～30mm.

The vegetation soil layer is an inorganic matrix, the organic sludge compost that produces by the flyash with loose structure, municipal sewage plant, the mineral resources humic acid fertilizer, the absorbent polymer material that form through chemically treated weathered coal and have good dispersion the clay mineral material--mixing such as bentonite are formed, its thickness is 10～30mm, and also can be made into thickness is the banded vegetation soil layer of sheet of 5～20mm.

Sowing fibrage, vegetation soil layer and liner fibrage contain the thick matrix of soilless culture that organic and inorganic matrix is mixed formation common the composition, grass seeds is sprinkling upon on the sowing fibrage, its root growth is on vegetation soil layer and liner fibrage, can obtain a large amount of, sufficient water-fertilizer nutrient, so thick matrix becomes the inoculating bed on lawn.

Separation layer is made by agripast film or plastic material, and its effect one is to support whole lawn, and the 2nd, the ground of lawn and storing, metope are separated by.

The thick matrix lawn soilless of the multi-layer combined type that the utility model provides, the outstanding availability that improves water-fertilizer nutrient that embodied is economized ability fertile, preserve moisture and fertility with water saving, can effectively economize on water 50%～70%, economizes fertilizer 30%～40%.This lawn plant can be resisted 30～50 days arids in vegetative period, but non-growing period water conservation 50～80 days, and well developed root system, cauline leaf is sturdy flexible, and the green phase is long, and resistance, disease and insect resistance performance are good, and generally all surpass 4 years service life.Plurality of advantages such as the thick matrix lawn soilless of multi-layer combined type has the survival rate height, view is strong, growth is rapid, cheap, manageable, easy maintenance, convenient transportation, can be used for public place, airport, office building, auditoriums, hotels, dwelling house, the table soil of special geology environmental conditions such as especially suitable all kinds of domatic (need to beat anchor pole or stake is fixing), mine tailing, slag accumulation of dam, desertification poor and barren land, saline land is afforested, the recovery of vegetation is for people build green living space.
