Description

Netting twine water culture floating bed

Technical field the utility model relates to a kind of utensil of plant floating cultivation, in particular for eutrophication water is carried out " biological cleaning ".

Background technology " netting twine water culture floating bed " is the utensil of a kind of artificial floating cultivation plant, be placed in the water behind some hygrophytes in cultivation on this artificial plant cultivation floating bed waterborne, constitute a kind of can be in the biological and ecological subenvironment of " chinampa " of water float shape." chinampa " is meant originally because peat course come-up works, the plant part of loke shore is cut off, and swims in a kind of natural phenomena of the water surface.So be also referred to as " artificial article floating island " after " netting twine water culture floating bed " is combined into the certain scale size.

The title of " artificial article floating island ", the BESTMAN company by Germany before 20 years proposes, and is mainly used in the plantation economic plants.There are shape and structure, the manufacturing materials of " artificial article floating island " that several country invents all different now.In the prior art, the artificial floating island of Japan be with the inflation rubber raft as floating bed, place the plant cultivation layer that the chassis that formed by the cocoanut fiber braiding and peat are formed on the floating bed; The artificial floating island of the U.S. then adds expanded polystyrene (EPS) or expanded polystyrene (EPS) and adds materials such as special synthetic resin, salinization ethene synthetic resin, concrete and be made into floating bed with filling in the different stainless steel tube of thickness, for the plant corpus on the fixing floating bed, matrix such as peat, vermiculite have been placed in the above as the plant fixed bed.Above-mentioned two kinds of artificial article floating islands, each floating bed area are generally all more than 100 square metres, and are bulky, material is heavy, and inconvenience is installed and discharged, and its cost is also very high, is difficult to large tracts of land and promotes the use of.

In recent years, because environmental pollution, the river of China, water body in lake pollute serious day by day, and a lot of rivers, water body in lake can't bear to drink.Even more serious is, a lot of rivers, water body in lake blackening are smelly, have a strong impact on people health, and people have adopted and a lot of physics can not deal with problems with water tackling method chemistry.In order to seek solution better, our seminar is under the Department of Science and Technology subsidizes, take the lead in adopting " biological floating island on the vegetation water " technology that the water quality of eutrophication such as lake, river, irrigation canals and ditches is carried out " biological cleaning " at home, utilize ecological engineering principle, the content of the COD in the degradation water, nitrogen, phosphorus is as the water environment treatment technology.By years of researches and experiment, obtained significant effect.

This technology is as carrier with artificial bio-membrane's floating bed, moisture loving plant is planted on the floating bed, it is placed to the water surface of eutrophication water, absorption by plant root on artificial bio-membrane's floating bed, suction-operated and species competition restriction or checking relation in five elements mechanism, cut down the nitrogen in the enrichment water body, phosphorus and organic substance, thereby reach the effect that purifies water, create the environmental condition that suitable multiple biology lives and multiplies, rebuild and the recovery aquatic ecosystem in finite region, and by results plant method it is moved away from water body, water quality is improved, it is clear that water body becomes, create the target of graceful water environment.Plant floating cultivation floating bed itself also has suitable covers, wave absorption, provides effect such as feed, has constituted the good condition that fish are lived, and can be used as the fish place of living, and also can be used as the place that lay eggs bed and the aquatile of fish perch.Plant on the plant floating cultivation floating bed forms after the natural community, also can be used as the space of living of birds, insects.Therefore, " artificial bio-membrane's floating bed " has multiple ecological functions.

In order to develop " the artificial bio-membrane's floating bed " that is fit to China's national situation, originally, we adopted foamed plastics as buoyancy aid, got the small sircle hole that is evenly distributed on foamed plastics, the various suitable plants of plantation have good clean-up effect through experiment to water body on circular hole.But because foamed plastics is broken easily, can't forbid the setback of stormy waves waterborne, and because serike in the small sircle hole on foamed plastics, plant corpus is difficult for fixing.Afterwards seminar to adopt bamboo again be that buoyancy aid is made artificial floating bed, effect is also fine, not only cost is low, raw material is also extensive, has also applied for utility model patent thus.But owing to bamboo easily breaks, and soak time has been grown and can have been fallen apart in water, so also there is certain problem.

Along with the attention of people to environmental problem, to the particularly also very concern of natural landscape situation of waterside of natural environment, therefore, " artificial bio-membrane's floating bed " not only created the biological space of living because of having, improved view, wave absorption, create waiting beyond the integrated function of the diversity ecosystem, also have special and application prospects in the water quality that purifies closed waters water bodys such as lakes and marhshes or pond, reparation eutrophication pollution.

The summary of the invention the purpose of this utility model provides a kind of suitable China's national situation " netting twine water culture floating bed ".Existing in order to overcome " artificial bio-membrane's floating bed " volume is big, quality is heavy, plant is difficult for deficiency fixing on floating bed, the technical scheme that its technical problem that solves the utility model adopts is: be cut into needed length with the thicker bamboo trunk of diameter, be combined into ring bodies as biologic float bed buoyancy aid and frame, walk around frame with two nylon ropes, and make it to be in " well " font and intersect and to be fixed on the frame on ring-type buoyancy aid four limits, with the fixing plant corpus of cotton rope, substituted peat, matrix such as vermiculite are as the fixture of plant, because peat, matrix such as vermiculite are in the water culture technology, be that a kind of fixedly plant corpus prevents the effect that lodges, as fixing plant otherwise, then can replace.Therefore " netting twine water culture floating bed " to have a volume light and handy, durable in use, characteristics such as cheap.Long period of soaking is pollution-free to water body in water body.Do not place any cultivation matrix above this plant floating cultivation floating bed, plant directly is planted on the groined type crunode of being made up of nylon rope above the floating bed, and by the fixing plant on the floating bed of nylon rope, root system of plant directly stretches into water body and absorbs nutrient in the water.It is particularly suitable for using in the vast rural area of China, also is convenient to install and carrying.The present invention can be interconnected and to be built into the disjunctor that area varies in size according to different waters biologic float bed by a plurality of monomers " floating bed ", installs and discharge all very convenient.The beneficial effects of the utility model are: not only can gather materials on the spot, reduce the cost of floating bed significantly, be convenient to install and discharge and apply, and to the beautifying of waters view, and the improvement that water body dyes, and the protection of ecotope and reparation have important function.
