Abstract

A method for fast forming the community of submerged plant in lake features that 6 vegetation combinations of 4 local submerged plants in lake are planted in the lake.

Description

Method for quickly growing groups of water plants in lake
One, technical field
The invention belongs to the resource-environment projects technical field, relate to a kind of method of utilizing local species to carry out lake submerged vegetation recovery.
Two, background technology
The nature lake ecosystem comprises opens wide waters, submerged vegetation zone, floatingleaved vegetation band, 5 parts in the water zone of vegetation and the loke shore Lu Sheng zone of vegetation very.
In China, because body eutrophication is more serious in recent years, its submerged vegetation zone is also in rapid decline.As forfeiture and the degeneration of the vegetation of primary productivity, cause the collapse of many lake aquatic attitudes system, the lake self-purification capacity disappears substantially.
In view of this, when cutting down the pollutant input, the aquatic community that recovery and reconstruction had been collapsed already, improving the lake self-purification capacity is the key of dealing with problems.With regard to submerged vegetation because the dynamic action of water surface wave, exist during it is rebuild plant easily be compromised, easily with difficulties such as current arbitrarily wave.At present, fundamental method is to adopt from healthy submerged vegetation zone artificial results plant, plants these plant at lakebed earlier, and then progressively discharges water and flood the method for plant; This method can not solve the low problem of plant survival rate, can not solve that plant causes the recovery efficient of submerged vegetation lower with the problem that current arbitrarily wave between blowoff period, need constantly repair.Therefore, field planting and build group submerged plant and remain an open question how fast and effeciently.
Three, summary of the invention
The objective of the invention is:
Invent a kind of field planting fast and effeciently and build the simple and easy method of group submerged plant, 6 vegetation combinations adopting this method plantation to be made up of 4 kinds of original inhabitants' lake submerged plant through water form stable lake submerged plant through water group, rebuild healthy aquatic ecosystem.
Technical scheme of the present invention is:
Originally building group seedling of method employing is the seedling that obtains from tissue culture method, can guarantee that all individualities have identical specification, 3-5 centimetre of its height.
Practice between seedling stage at seedling, the soil of planting the seedbed adopts loam; Its height of seedling when 90% can carry out field transplanting during greater than 10 centimetres.
2 strain seedlings and soil are together taken out from kind of seedbed,, form the root system-soil spheroid of 2-3 centimetre of diameter, form a strain clump immediately at the outer manual kneading clay of soil; Its stickiness is not cracked into standard with placement in water body after 24 hours.
Between planting season, the degree of depth of construction area water body in lake is adjusted at 30-50 centimetre.
By the rule of the how circular expansion of aquatic vegetation, make up circular submerged plant group; 20 meters of round diameters, plantation plant spacing 20 strain clumps/square metre, randomized arrangement; Guarantee that 1/3 of root system-soil spheroid is buried in the bottom mud in lake.
In 1: 1 ratio of plant, 4 kinds of submerged plants are constituted eel grass-water caltrop group, eel grass-watermifoil group, eel grass-hydrilla verticillata group, water caltrop-watermifoil group, water caltrop-hydrilla verticillata and 6 group's combinations of watermifoil-hydrilla verticillata respectively.Spatially not overlapping between each combination.
After construction was finished, visual plant growth condition progressively increased the degree of depth of water body, but is difficult for above 2 meters.
Effect of the present invention is:
In 1: 1 ratio of plant, constitute eel grass-water caltrop group, eel grass-watermifoil group, eel grass-hydrilla verticillata group, water caltrop-watermifoil group, water caltrop-hydrilla verticillata and watermifoil-hydrilla verticillata group; 20 meters of each group's diameters are transplanted plant 6280 strains; Survival rate of plant is more than 95%, and the disposable reconstruction that has completed successfully heavy water aquatic vegetation is demonstrated; The clean dirty ability of its decontamination is also considerable.The present invention had both solved the low problem of survival rate in the present lake submerged plant through water reconstruction, had solved the problem that plant is arbitrarily waved between blowoff period again.
Four, embodiment
This method is demonstrated at the Taihu Lake basin water body in lake, has obtained about 3500 square metres lake submerged vegetation.Its concrete working method of implementing is as follows:
The first step, is determined the height of current, the depth of water and the printing opacity degree of depth at on-the-spot investigation; Implement seedling specification and other construction materials of ecological instrument kind, tissue engineering technique personnel put in place.
Second step, seedling and the soil of practicing the seedling stage is taken out jointly from the seedbed, add clay at the soil skin, make root system of plant and soil form a spheroid.
The 3rd step is at construction area, by circular diameter plantation seedling.Each vegetation combination has a slice of one's own.
At last, after engineering is finished, monitor, prevent that too low light transmittance from threatening the survival of plant instrument kind the water body light transmittance.

Claims (3)

1, a kind of method for quickly growing groups of water plants in lake, it is characterized in that the local species that are used to from tissue cultivating seedling make up stable submerged vegetation, its step comprises: together take out 2 strain seedlings and soil (1) from kind of seedbed, immediately at the outer manual kneading clay of soil, form the root system one soil spheroid of 2-3 centimetre of diameter, form a strain clump, its stickiness is not cracked into standard with placement in water body after 24 hours; (2) between planting season, the degree of depth of construction area water body in lake is adjusted at 30-50 centimetre; (3) make up circular submerged plant group, 20 meters of round diameters, plantation plant spacing 20 strain clumps/square metre, randomized arrangement guarantees during plantation that 1/3 of root system-soil spheroid is buried in the bottom mud in lake.
2, according to the described method kind of claim 1 planting submerged plant group, it is characterized in that in 1: 1 ratio of plant, 4 kinds of submerged plants are constituted eel grass-water caltrop group, eel grass-watermifoil group, eel grass-hydrilla verticillata group, water caltrop-watermifoil group, water caltrop-hydrilla verticillata and 6 group's combinations of watermifoil-hydrilla verticillata respectively, form 6 basic submerged vegetation units; Spatially not overlapping between each combination.
3, recover and lake healthy water ecosystem rehancement application in engineering the lake submerged vegetation according to the described method of claim 1.
