The method is characterized by comprising the following steps: 1, getting the submerged plants to be replanted and needed soil ready in advance; 2, transporting the submerged plants needing to be replanted and the soil to the construction site; 3, wrapping the submerged plants into individual casting-for-plantation packages manually, wherein each individual casting-for-plantation package is composed of the corresponding submerged plant, the corresponding soil and a biological bag, the soil wraps up roots and the joints between the roots and the rhizomes of the submerged plants, and each biological bag wraps up the root of the corresponding submerged plant and the exterior of the soil at the joint of the root and the rhizome in a sleeving mode; 4, molding the part, where the soil is located, of each casting-for-plantation package into a tower body shape; 5, carrying all the individual casting-for-plantation packages to a maintenance boat, and then rowing the maintenance boat to the blank area of the bottom layer of a water body for casting for plantation.
Description
Technical field
The present invention relates to a kind of Water Ecological Recovery method, particularly relating to a kind of Water Ecological Recovery method with reseeding submerged plant under water condition.
Background technology
In recent years, along with developing rapidly and the rapid expanding of population of economy, a large amount of industry and domestic pollutant enter in river and lake, cause the severe contamination of water body and going from bad to worse of water quality.Water pollution has become a kind of key factor of China and even global water resources shortage.Wherein body eutrophication is the phenomenon the most general in water pollution.Along with people are to the raising of the understanding of importance of environment and the improvement of Environmental pollution problem and the lifting of supporting dynamics, the research of body eutrophication recovery technique has become domestic and international soil-plant nutrient, the forward position of environmental ecology disciplinary study and focus.In the various means that eutrophication water is repaired, water plants ecological reestablishment is a kind of low, effective, that operating cost is low new technology that consumes energy, and has been widely studied and applied in Water Ecological Recovery engineering field because it is with the obvious advantage.
The water plants adopted in current water plants ecological reestablishment mainly contains 4 classes: submerged plant, emergent aquactic plant, fluitante, floatingleaved plant.Wherein submerged plant plays a major role in the purification of water quality, accounts for about 80%.Can say that the upgrowth situation of submerged plant is the key of a Water Ecological Recovery engineering project success.In Water Ecological Recovery Construction of Engineering Projects, there will be submerged plant planting complete after have subregion to be still blank situation.Cause the reason of this phenomenon to be that the submerged plant death in this region or the submerged plant of plantation come up because bed mud is too rare and floating, so just need to reseed submerged plant to white space.The existing method of reseeding has two kinds: a kind of for reseeding submerged plant to white space again after precipitation; Another kind of for adopting bamboo punt-pole cuttage to carry out reseeding submerged plant under the existing depth condition of maintenance.All there are some defects in these two kinds of methods: reseeds submerged plant after precipitation and plenty of time and financial resources not only will be spent to carry out precipitation, and destroy original ecosystem after precipitation, delayed the time limit that the ecosystem reaches balance; And adopt bamboo punt-pole cuttage also to have following inferior position: 1) water has buoyancy, especially profundal zone, and bamboo punt-pole not easily probes into water bottom, and is also a problem to the physical power loss of workman.2) if bed mud is rarer, the submerged plant of cuttage is easily floating to come up.3) reseed efficiency too low, labour cost cost is high.4) the submerged plant survival rate of reseeding is lower.
The existence of these problems above, needs to propose new technical scheme and solves.
Summary of the invention
The object of the invention is to provide a kind of Water Ecological Recovery method with reseeding submerged plant under water condition, it not only effectively can be implemented to carry out submerged plant to water bottom white space and reseed, and have easy construction, simple to operate, reseed the features such as the high and relative cost of efficiency is low, the submerged plant survival rate of simultaneously reseeding is high, can realize vegetative coverage and the purification of water quality of water bottom fast.
The present invention is such realization to achieve the above object: a kind of Water Ecological Recovery method with reseeding submerged plant under water condition of the present invention comprises the following steps:
A) submerged plant reseeded and required soil is got out in advance;
B) submerged plant needing to reseed and soil are transported to job site;
C) manual submerged plant is rolled into throws kind of an individuality, described throwing kind of an individuality formed by submerged plant, soil and biobag, described soil wraps root and the rhizome junction of submerged plant, and described biobag is sleeved on outside the soil of root and the rhizome junction wrapping submerged plant;
D) fashion in tower body shape by throwing kind of an individual soil position;
E) be unifiedly transported on maintenance ship by individual for throwing kind, then draw to water bottom white space and carry out throwings kind.
Described throwing kind of an individual submerged plant used is 2 ~ 4 strains.
Described throwing kind of an individual submerged plant used is short raw eel grass.
Described throwing kind of individual soil used is 200g, and the fertility index of the individual every 100g of soil used of described throwing kind is containing organic matter 1.0% ~ 1.2%, total phosphorus 0.07% ~ 0.09%, total nitrogen 0.20% ~ 0.35%, total potassium 1% ~ 3%.
Described kind of individual soil used of throwing adopts pond sludge.
Described biobag be a kind of nonwoven cloth material make there is the ecology bag easily decomposed and to water body non-contaminating character, the perisporium of biobag bottom is distributed with the aperture that aperture is 3 ~ 4mm.
A kind of Water Ecological Recovery method with reseeding submerged plant under water condition of the present invention had once been the provincial capital, Poly Dong Jiang, Guangzhou artificial landscape lake, the ground such as Shenzhen Huawei base G district artificial landscape lake and Guangxi University Bi Yunhu utilize throwing kind of individual enforcement to reseed submerged plant, and concrete effect is in table 1, table 2 and table 3.
