Description

A kind of economic and environment-friendly type submerged plant eel grass cultivation rattan felt and method for planting

Technical field

The invention belongs to water and soil conservation, Water Ecological Recovery, Ecology building, ecological aquaculture cultivation, ornamental water scenery small stream pond and The technical fields such as ornamental aquarium are related to the three-dimensional environmental protection cultivation rattan felt of submerged plant eel grass and method for planting, more particularly to one Kind will be implanted with heavy hardship based on important link -- the quick cultivating technology of submerged plant in waste water ecological control and Ecology building The rattan felt of grass can quickly be jettisoninged plantation with large area.

Background technique

Clean water source is indispensable natural resources in people's production and life on its periphery, is related to a people from family Family, a village, an even city, a national survival and development.It reforms and opens up to the outside world the prometaphase in China, due to people couple Environmental protection consciousness it is indifferent, cause it is various life and industrial or agricultural sewage it is unordered arbitrarily rough formula excess emissions, cause China city Town and periphery overwhelming majority aquatic ecosystem are degenerated and are destroyed；Currently, China is just reinforcing the improvement and guarantor to water throughout the country Shield, regulation prevent the various sewage direct emissions of industry, agricultural and resident.And after section dirt or waters of eutrophication is controlled There are many kinds, such as the various types of technical methods of physics, chemistry, ecological management for reason method, but these methods require for a long time Put into a large amount of material resources and manpower.

Clear water type ecosystem constructing technology is the main and most efficient method of current sustainable ecological management, such as Guangzhou The water body treating of city, lake park, Li Gulf, extra large pearl wetland park etc.；Clear water type ecosystem constructing technology refers to water ecology system System is changed into the series of process of clear water state from muddy water state, and theoretical basis is stable state transforming principle.Aquatic ecosystem building Technology can effectively remove the nuisances such as eutrophy salt, heavy metal ion in waters and increase oxygen-containing in water, holding water body Clean state, while also having and continuing not inhibit the sustainability of algal grown, the newly generated sewage of purification after ground day by day It harnesses the river function；The emphasis of aquatic ecosystem constructing technology and main capital investment are the recovery or reconstruction of submerged vegetation；In water very Water plant, fluitante and floatingleaved plant class, since its photosynthesis is to carry out in the sky, without can increase oxygen content of water； Although microalgae plant can increase the oxygen content in water, but be difficult to control its population density, and seriously affect water transparency, It is unfavorable for the growth of waters lower layer submerged vegetation, and is easy to produce harmful algal tufa phenomenon.Submerged plant (submerged plants) Refer to that plant is entirely located in the aquatic macrophyte that fixed existence is sought below water layer, all absorbable water of each section of plant Divide and the institutional frameworks such as root, stem, the leaf of this kind of plant of nutriment are all sufficiently flexible, without obvious xylem, leaf is mostly band-like Or it is Filamentous, root is fibrous root, such as eel grass, hornwort, watermifoil, black algae.But most of submerged plants have branching rate function, such as With spinney in water, it is easy the entire Water space that has a full house, the quick-fried pool is caused to spread unchecked and lack landscape effect；And eel grass growth is such as water Lower coniferous forest can construct the stereoscopic landscape space of a width clear state under water, have powerful landscape value, be that current clear water type is raw Unique dominant population in state system constructing technology.It is perennial heavy that eel grass (Vallisneria natans) is subordinate to Hydrocharctaceae Vallisneria Water plant is distributed widely in China, each provinces and regions, north and south, is suitable for fresh water rivers and lakes, reservoir pond, gully gush canal, streams clear spring Equal waters.Meaning eel grass of the invention is the common name of eel grass platymiscium.Eel grass is clear in current waste water ecological control, water ecological restoration and water In state Scene construction etc., is just wideling popularize and planting in China as unique dominant population.In natural water area eel grass population seed Amount can achieve .01E6/square metre of 1 .68E4 ~ 1, but 1 .28 ~ 3 millimeter long for strip, diameter are less than 0.5 milli The eel grass seed of rice influences greatly vulnerable to variations such as the depth of water, water quality, temperature, illumination, water flows, and seed builds population in natural water area Vertical and restitution is seldom, and the major way that eel grass population foundation and annual population restore at present is vegetative propagation.

The growth of eel grass must be the submerged plant that implantation ability normal growth in subaqueous soil in root builds group, otherwise Underwater can be swum in, although can survive, population cannot be established at the bottom；The exposed mistake very easy in air of eel grass leaf Water is dead.At present in water harnessing field, the traditional cultivation method of eel grass is: the water for needing to cultivate the waters of eel grass being first discharged to water It is deep be lower than 5-10 centimetres hereinafter, and grassiness fish in water and sludge aquatic animal are cleaned out, then by manually using Latter one root and stem of certain plants of the root and stem of certain plants of eel grass plant rhizome portion envelops can be inserted into subaqueous soil by finger again；In eel grass fibrous root not to soil four Before week diffusion implantation, do not have pull-out capacity, it is ensured that just the water transparency and water body in waters do not flow after plantation, it is desirable that in water The minimum intensity of illumination requirement of photosynthesis needed for illumination can satisfy eel grass leaf；It is subsequent conserved at level ground during, be Plant, which takes root, to be grabbed after mud consolidates bed, and clean water source is gradually injected.The method is suitable only for that the independent waters of water can be drained, plantation Vulnerable to season, rainfall, Hydrological Effects and limitation in operation process, it is also necessary to spend a large amount of manpower and financial resources, and be unsuitable for opening The vast natural water area of property or mobility；The early spring north risen is in southern winter and melting of ice and snow water temperature, water quality is saturating Lightness best season, but low water temperature is unsuitable for planting operation in artificial water；The method is also not suitable in rigid water-bed plantation.

In order to quickly establish or restore submerged plant eel grass population, the multifarious hydrology, weather, temperature, ring are being faced Under the natural restrictive condition in the different waters of guarantor etc., that is, wants that difficulty of construction and cost can be reduced, also want before capable of simplifying construction procedure It puts, in existing disclosed Specific construction technology, all haves the defects that more or less.Plantation skill such as based on point Art: throw throwing method (application number: 201720124687,201810154867 etc.) and by tool plantation method (application number: 201110077994, cultivation technique 201210076232,201721801734 etc.), vulnerable to water flow, subaqueous soil condition, etc. All many condition limitations, can not realize large area, quickly plantation；As mud and fiber be matrix be laid with plantation method (application number: 200310111602,201521009232,201611222257,201710732486,201711472589), there is breedings The turf grass growing time period is long, and the conditions such as nursery place and hydrology for needing equal proportion limit, and long construction period；Such as application number For flowing waters protection against erosion technology in 201711442853, need barrier dam, backfill in grid and bitter kind of plantation after need plant Take root and grab mud and consolidate that the activity durations such as bed curing period are long, and the construction time is vulnerable to Hydrological Effects；Also 2 in its claims described in: Submerged plant turf is set in three-dimension vegetative net, and only uses seed, fiber and matrix in the prior art, in suitable season With at a temperature of, after a long period, it can just grow into and constitute blockiness heavy of certain structure by root system of plant and fiber Water plant turf, but the turf of land traditional sense can not be grown into, because the turf of land traditional sense is by root It a kind of could resist the turf of certain tearing configuration together with grape stem, and the Portugal of the not no wood substance component containing toughness of fresh water submerged plant The plant of grape stem uniquely expands numerous eel grass by grape stem, and grape stem diameter is very fragile, easily broken less than 2 millimeters.

Artificial waterscape is indispensable in living environment periphery and occupies an important position in garden landscape that these largely divide Before the village Bu behind the house, residential communities, the enclosed landscape water body such as in garden and park, although most of do not have external contamination source Be directly discharged into, but there is the cumulative effect of nutritive salt and oxygen content are low, water body is transparent low, is arranging the sunlit summer by force Season, water quality will usually become nigrescence or alga eruption.This kind of waters, for antiseep, usually uses hardening pond when building again Bottom, it is difficult to plant submerged plant, most of waters have to let matters drift, and good in economic efficiency property can also endure great number water Take, water body cleannes are reached by refreshing the water periodically, but causes the waste of great lot of water resources；Such as the petrifying water bottom in Guangzhou City Landscape pond, 1-2 or more tap water will be changed in a week by being averaged in summer.
