Description
Technical field
The invention belongs to the ecological restoration technical field in lake, be more particularly to a kind of top layer soft high organic bed mud shallow
The substrate improved materials in water lake, further relates to the system of the substrate improved materials of a kind of top layer soft high organic bed mud shallow lake
Preparation Method, also relates to the restorative procedure of a kind of top layer soft high organic bed mud shallow lake, can be applicable to top layer soft
The Ecological Restoration Project of high organic bed mud shallow lake.
Background technology
Submerged plant planting and recovery technique are the key technologies of Ecological Restoration Project, utilize aquatic macrophyte to repair water
Body and sediment pollution are to administer, regulate and one of the effective way suppressing body eutrophication.The whole growth course of submerged plant
All living in water, root, stem, leaf can absorb the nutrient substance in water, and its growth and development process absorbs water Middle nutrition exactly
The process of material, defines the hugest environmental carrying capacity and strong self-purification capacity.And rhizosphere microorganism degradable is organic
Pollutant, constantly purify water and repair bed mud.But for black smelly bed mud river course, black smelly bed mud is not covered and transforms
Processing, submerged plant is difficult to survive, and Ecological Restoration Project is difficult to popularization and application.But many natural shallow lake sediments pines
Soft, the content of organic matter is high, this special substrate is unfavorable for submerged plant growth field planting, typically can not directly plant planting submerged plant,
Or submerged plant survival rate is low, and Ecological Restoration Project is difficult to popularization and application.
Clay be a kind of containing the grains of sand seldom, have the soil of stickiness, can be as environment-friendly type substrate transformation materials application in lake
Substrate improvement project, but the clay of consolidation easily hardens and causes anaerobic environment, causes submerged plant root system to be difficult to grow and rot.
The space of substrate can be increased by adding loose porous modified ceramic filter bulb, add mineral improver Kaolin and can accelerate at the bottom of pond
Organic matter or the conversion of Humus, in Kaolin, trace element can promote root system of plant field planting and growth, and modified ceramic filter bulb
With Kaolin, there is strong absorption property, adsorbable bed mud and the nutritive salt such as Water, phosphorus, while repairing bed mud be in position
Submerged plant primary growth provides nutrient source, the biomembrane of ceramic filtration ball surface formation and submerged plant rhizosphere microorganism degradable
Mineralising Organic substance.Calper calcium peroxide is as the oxygenation agent of a kind of high-efficiency environment friendly simultaneously, can increase bed mud and the dissolved oxygen of bottom water body
Concentration, is conducive to improving water quality, accelerates organic removal in bed mud, promotes plant growing further.It is contemplated that pass through
Clay, Kaolin, enviroment protective ceramic filter bulb and calper calcium peroxide are mixed by a certain percentage and is applied to top layer as substrate improved materials
In the recovery project of soft high organic bed mud shallow lake, improve demonstration area living environment so that it is be suitable for submerged plant growth,
Effectively solve the problems such as submerged plant survival in soft high organic bed mud pool lake, top layer is difficult, the most floating, bed mud is had simultaneously
The pollutant such as machine thing carry out adsorbing in situ so that it is accelerate recovery and the structure of ecosystem.
Summary of the invention
It is an object of the invention to be difficult to apply restoration of the ecosystem work for above-mentioned top layer soft high organic bed mud shallow lake
The problem of journey, is the substrate improved materials that there are provided a kind of top layer soft high organic bed mud shallow lake, and this material has
There is formula reasonable, easy to use, with low cost, environmental friendliness, the advantages such as substrate improved effect is good, repaiied by substrate improvement substrate
Good living environment is built for submerged plant growth while rehydration body and bed mud.
Another object of the present invention is to there are provided a kind of top layer soft high organic bed mud shallow lake substrate to change
The preparation method of good timber material, this preparation method technological operation is simple, environmental friendliness.
Another object of the present invention is to there are provided the reparation of a kind of top layer soft high organic bed mud shallow lake
Method, this restorative procedure is easy and simple to handle, ecological, environmental protective, can improve substrate living environment so that it is be suitable for submerged plant growth, effectively
Solve submerged plant in soft high organic bed mud lake, top layer and be difficult to the problems such as Survival and growth, simultaneously to dirts such as bed mud Organic substances
Dye thing carries out removing in situ, the beneficially recovery of water area ecological environment so that it is recovery and the health of accelerating lake ecosystem are sent out
