Simple underwater lawn
The utility model belongs to water body environment technical field, particularly a kind of Simple underwater lawn.
In recent years, introspect water environment treatment thinking in the past one after another countries in the world, has proposed ecological new concept of harnessing the river.The most of waters of China has completed a section dirty task substantially at present, how to administer and becomes current main task.For ensureing water quality long-term stability, can only rely on biotechnology means.In restoration of the ecosystem process, we usually run into actual problem and are: low light according to, stormy waves is large, substrate is not suitable for etc., and problem causes submerged vegetation surviving rate low.The breeding potential of the eel grass of Hydrocharctaceae is high, and by tillering, growth is expanded numerous; Form seed submerged, Second Year is sprouted and is bred.Because breeding, the surviving rate of eel grass are high, phycophyta is had to obvious restraining effect, so it is most suitable to be used as repairing the waterplant of water body.But, how to guarantee that the fixing also normal growth of root of eel grass is the key point of underwater lawn, will directly have influence on the effect that water ecology is repaired.
Lot of domestic and international investigator has started to use eel grass seed to make sod of tape grass, open day is on March 26th, 2014, publication number is CN203498165U, and denomination of invention is " a kind of underwater lawn ", the growth matrix by the method with upper and lower two layers of mesh sheet double team nutrition soil layer as eel grass seed.This patent can provide a kind of applicable growth substrate for eel grass seed, but the cost of upper and lower two layers of mesh sheet is high, and net sheet easily pollutes after sinking under water.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Simple underwater lawn, this lawn is taking eel grass as submerged plant, use sponge not only to guarantee the penetrance of eel grass root system, improve in the surviving rate of eel grass, and cost is low, and environmental protection, making are simple, be applicable to implant mass.
The utility model is achieved through the following technical solutions:
A kind of Simple underwater lawn, comprise submerged plant, described submerged plant planting is on culture medium, described culture medium is made up of the nutrition soil layer on upper strata and the net sheet of lower floor, described nutrition soil layer be pond sludge and fertilizer in mass ratio for the ratio of 4:1 mixes, the mesh of described net sheet is 10 orders.
Wherein, described nutrition the thickness of the layer is 5cm.
Wherein, described net sheet is flexible materials.
Wherein, described flexible materials is degradable plant fibre film.
Wherein, described submerged plant is eel grass.
The beneficial effects of the utility model are:
1, the utility model adopts the net sheet of flexible material, as degradable plant fibre spunlace non-woven cloth, fenestra is 10 orders, can prevent rising of bed mud, the effect of fixing dirt bed, and be conducive to penetrating of Asia eel grass root system, promote the development growth of Asia eel grass root system and tillering of bud, improve the surviving rate of Asia eel grass.
2, the utility model adopts eel grass plantation, after implantation target water body, forms fast group, grows a large amount of zooplanktons and other hydrobionts, there is the effect of good water quality purification function and formation submerged forest, and breeding potential is high, easily survives, be applicable to implant mass.
3, the utility model cost is low, cost performance is high, is applicable to use in waters on a large scale, can obviously improve the living environment of lake environment and other biological, has profound purification, species diversity, the effect of beautifying the environment etc.
Brief description of the drawings
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram on the utility model Simple underwater lawn;
Fig. 2 is the finished product schematic diagram on the utility model Simple underwater lawn.
In figure: 1-Asia eel grass, 2-nutrition soil layer, 3-net sheet, 4-adult eel grass, 5-pool soil.
Below in conjunction with specific embodiments and the drawings, further set forth the utility model.
As depicted in figs. 1 and 2, a kind of Simple underwater lawn, comprises Asia eel grass 1, described Asia eel grass 1 is planted on culture medium, this culture medium is made up of the nutrition soil layer 2 on upper strata and the net sheet 3 of lower floor, the degradable plant fibre film that the material of this net sheet 3 is, and the mesh of net sheet 3 is 10 orders.By the rectangle of net sheet 3 cutting growth 10m and wide 1.3m, be layered on pond bottom compacting, net sheet 3 plays and prevents that bed mud from rising and fixing the effect of dirt bed, and facilitates monoblock net sheet to transplant; Degradable plant fibre film belongs to flexible materials, strong with the avidity of Asia eel grass root, is conducive to penetrating of Asia eel grass root system, promotes the development growth of its root system, plant tillering.
Nutrition soil layer 2 evenly mixes for the ratio of 4:1 in mass ratio for pond sludge and fertilizer, and its thickness is 5cm, sizableness of its size and net sheet 3.
Select harvesting in a year the Asia eel grass seed after drying and washing by rubbing with the hands, Asia eel grass seed is evenly sowed on Nutrition Soil, eel grass can germinate, eel grass root can pass and see through net sheet 3 from nutrition soil layer, thereby grow up to gradually the underwater lawn of about 10-15cm, can play and purify water, repair the effect of water body.
