Abstract

The utility model relates to a desertification control grass mat, which at least comprises an upper net, a fibrous layer, an organic layer, a liner layer and a lower net sequentially arranged and quilted into one body, wherein the organic layer comprises nutritional soil of which the thickness is not less than 10mm, water-retaining agent of which the volume is not less than 15 percent of the total volume of the organic layer, and seed. The utility model adopts mass water-retaining agent, and thickened the nutritional soil, thereby being favorable for the growth of the grass seed in the desertification environment, maintaining the required water and soil for ensuring fast growth, and forming a greening lawn, in addition, the fibrous layer composed of materials of agricultural wastes of straw, palm or hemp recycles the agricultural wastes, the fibrous layer can protect the grass seed before the grass seed come out, and can also perform national degradation in the later stage of lawn forming of the grass seed, and provide nutrients for the growing grass, thereby saving resources, and reducing manufacturing costs.

Description

Desertification treatment grass blanket

Technical field

The utility model relates to a kind of desertification treatment grass blanket, relates generally to the technical field of protection of natural resources and environment, relates in particular to the technical field of desertification treatment grass blanket.

Background technology

China is as large agricultural country, a large amount of agricultural wastes are arranged every year, comprise stalk, straw, straw, coconut husk, also having annual golf course is the useless grass that cuts the grass on a lawn and produce, the processing of these agricultural wastes will consume great amount of manpower and material resources and financial resources, in addition, the peasant burns fire that rice and wheat straw causes, atmospheric pollution and to the influence of takeoff and landing and highway, railway traffic safety, become a mortal malady of governments at all levels, how can these discarded objects be recycled, to have become urgent problem.

The simultaneous needs of economic development, constantly farming, woods land used are used for building house and developing industry, vegetation is constantly destroyed, and what bring is the formation of large tracts of land desertification of land, how can rationally administer desertification, preventing erosion also becomes urgent problem.

At present, there are some to be used for " the turf volume " of farmland greening, it can be used for the improvement of desertification, but but needing to take a large amount of farmlands turf plant transplants then, not only take a large amount of high-qualitys soil and destroyed soil property, and cause the waste of the expense of a large amount of transportations and transplanting, increased the turf establishment cost.

The utility model content

The purpose of this utility model is to overcome the defective of prior art, and a kind of desertification treatment grass blanket is provided, and not only can administer desertification effectively, and recycle discarded object, economizes on resources the purpose that reach desertification treatment, prevents erosion.

The utility model realizes that the technical scheme of above-mentioned purpose is:

A kind of desertification treatment grass blanket, it comprises at least and setting gradually and quilting is online, fibrage, organic layer, the lining and off line of one that wherein said organic layer comprises that thickness is not less than 10 millimeters nutrition soil.

Because a large amount of water-loss reducers is adopted in the utility model utilization; and thickeied nutrition soil; can help grass seeds in the desertification ambient growth; required moisture and soil property have been kept; it can be grown as early as possible; form greening lawn; in addition; with stalk, palm fibre or these agricultural wastes of fiber crops is that raw material constitutes fibrage, has recycled agricultural wastes, and fibrage not only can play protection before grass seeds grows; and again can natural degradation in later stage that grass seeds growth forms the lawn; for the grass that grows out provides nutrient, saved resource, reduce manufacturing cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

As shown in Figure 1, the utility model provides a kind of desertification treatment grass blanket, it comprises at least and setting gradually and quilting is the online 1, fibrage 2, organic layer 3, lining 4 of one and off line 5, and wherein said organic layer comprises that thickness is not less than 15% water-loss reducer and seed that 10 millimeters nutrition soil, volume is not less than described organic layer cumulative volume.Can also spread a small amount of fertilizer in the described organic layer, be beneficial to the grass seeds growth.Can select for use different mixed sowing of turf grass in organic layer, be convenient to piece together and establish the lawn pattern, and the survival rate height, certain inhibition weeds function had.

Described nutrition soil thickness can be preferably the nutrition soil of 20-30 millimeter.The thickness of described nutrition soil is by different geological environment decisions, and this can be laid on different geological environment decisions according to careless blanket, and the soil property of environment is relatively poor then to adopt thicker nutrition soil, if soil property is better, otherwise then.Described nutrition soil also can be 40 bold and unconstrained meters, 50 millimeters or 80 millimeters.The nutrition soil of thickening can be kept grass seeds in the demand of desertification environment to soil property.

Described water-loss reducer can be the water-loss reducer of the 15%-30% of described organic layer cumulative volume for volume.The volume of described water-loss reducer can account for 15%, 18%, 20%, 25% or 30% of described organic layer cumulative volume, adopts a large amount of water-loss reducers, can help grass seeds in the desertification ambient growth.

Described fibrage is paved into by plant fiber bodies, degradable.Described plant fiber bodies forms described fibrage in the mode of tiling, need not compacting, and simple to operate.Described fibrage can be the fibrage that is paved into by stalk, palm fibre and/or fiber crops, adopts stalk, palm fibre and/or fiber crops to be paved into fibrage, makes the recycling of agricultural wastes, economizes on resources.Described stalk, palm fibre and/or fiber crops are generally is not with earth and moisture to be not more than 10% stalk, palm fibre and/or numb, be not with earth, be subjected to the pollution of bacterium in the earth in the time of can preventing the grass seeds growth, also growth has guaranteed suitable moisture to grass seeds in the control of moisture, is 3%, 5% or 8% stalk, palm fibre and/or numb usually with moisture.

Fibrage not only can play protection before grass seeds grows, and again can natural degradation in later stage that grass seeds growth forms the lawn, for the grass that grows out provides nutrient, has saved resource, has reduced production cost.And fibrage is even usually, smooth and neat in edge, can use in stalk, palm fibre and/or the fiber crops one or more to be raw material when laying described fibrage.

Described upper and lower net all can be for being formed by the braiding of plastics silk.Because careless blanket is the reticular pattern structure, thereby does not need to fix with wire netting again, economizes on resources.

Described plastics silk is generally the degradable polypropylene plastic silk, and these plastics can be degraded, and avoid environmental pollution.The described mesh of going up stratum reticulare and following stratum reticulare is arranged and is neat, uniformity usually, is convenient to the homogeneity and the regularity of grass seeds growth.

Described lining can be nonwoven or soft reel lining paper, has both played the effect of supporting organic layer, can degrade fast naturally again, is beneficial to grass seeds and takes root.

It is uniform that each layer of grass blanket is convenient to careless blanket through the machine quilting, than bonding more environmental protection.

Environmental protection grass blanket just can play well before the lawn grows up to and fix the sand, bank protection and the effect that prevents erosion, and this construction project such as repair the roads to cutting into a mountain has the very high value of environmental protection.
