Abstract
The present invention relates to a method for preparing and using a plant restoring cultured body for polluted soil, which belongs to the technology for treating pollution in the field of environment. In the method, the characteristic of culturing medium and the characteristic of soil improvement of peat are utilized, and the method is combined with an air root-ordering method; water retention agent, water soluble adhesive, rooting agent and slow acting-release fertilizer are added; the obtained substance is pressed by a forming machine to be prepared into a formed nutrient body for the growth of plants; plant seeds and seedlings for restoring polluted soil are planted and cultured in a formed peat body which is not contained by a carrying container, and are transplanted to polluted soil, so the survival capability, the biomass and the growing speed of plants in polluted soil are enhanced. The method provides a culturing body which can be conveniently used and can promote growth for restoring plants, and provides a novel soil improving agent and plant restoring method which can enhance the fertility of soil for polluted soil. The present invention can be used in the ecological environment restoring field for restoring soil which is polluted by heavy metals and organic matters, for recovering vegetation in the waste places, etc.
Description
Technical field
The invention belongs to the pollution control technology in the environmental area, relate to a kind of preparation and restorative procedure thereof of polluted soil repairing plant culture.
Technical background
Industrial and agricultural production causes a large amount of soil pollutions, and not only soil fertility degeneration reduces crop yield and quality, and worsens environment, and jeopardizes human life and health by food chain.The improvement of contaminated soil has become the difficult point of environmental pollution and improvement.
At present, lack cheap and purification techniques effective contaminated soil.The conventional method that is adopted as some physics such as vitrifying, electrodynamics, heat treatment, surfactant or chemical aspect, cost costliness not only, complicated operation, and usually cause that soil texture destroys, biological activity of soil descends and soil fertility degeneration.The method that adopts microorganism to repair though relative cost is lower, has certain place to go effect, and the domestication of inoculating microbe, the survival rate in the soil is low and the application of security restriction microorganism recovery technique.Adopt plant extract, the plant method of repairing such as fixing, simple to operate because of its cost is low, non-secondary pollution and be subjected to various countries day by day and pay attention to.Because the toxicity of pollutant produces certain inhibition to growth and development of plants, cause plant population to be difficult in and form the necessary biomass of matter that clears the pollution off on the contaminated soil, thereby cause the soil detoxification processes very slow, effect is not good enough, limits it and further promotes the use of.For improving the shortcoming of phytoremediation, people utilize seed pelleting, and polypots method such as grow seedlings improves the energy for growth of rehabilitation plant at contaminated soil, though obtain certain effect, but still can't satisfy actual needs.
The present invention is organic matter, the content of humic acid height that utilizes natural humatite peat to have, the absorption sequestering power is strong, have stronger ion-exchange capacity, salt balance control ability and biological physiology spread effect, be the good existence carrier of plant and the characteristic of soil conditioner, in conjunction with whole technology of air, for rehabilitation plant provides a kind of easy to use, can promote the culture of growing; For contaminated soil provides a kind of safety, the soil conditioner that can increase soil fertility and the new method of plant combined reparation.Under the condition of no soil secondary pollution, improve survival rate, biomass and the speed of growth of polluted soil repairing plant, increase the soil organism, microbial activity and soil fertility, accelerate soil pollutant, removal, recover soil environment safety.
Summary of the invention
It is primary raw material that the present invention adopts China's low level eutrophy meadow peat, with addition of appropriate amount of auxiliary materials water-loss reducer, water-soluble binder, root-growing agent, long-acting slow-release fertilizer, make the cylinder that has kind of hole and cutting hole through make-up machine, to be used for the vegetable seeds of contaminated soil reparation or the solid shape peat body that seedling is planted in no carrying container, along with the plant growth, root can coil knot around peat body, because air can make the root that exposes outside peat body wilt, suppress the root elongation, promote fibrous root breeding and main root branch.When plant transplantation when soil is planted because the increase of root branch can enlarge root district area, promote existence and the growth of plant in contaminated soil, realize the plant extract of soil pollutant and root system are fixed and reached the purpose of soil remediation.Be used for rehabilitating soil plant can by sowing, divide seedling and cuttage mode in the plantation of peat culture, after be transplanted to and carry out plant-peat on the contaminated soil and unite and repair improvement.
The used primary raw material of the present invention is a low level eutrophy meadow peat, requires organic 〉=30%, humic acid 〉=25%, water content 25%-35%, ash content≤40%.
Prescription of the present invention: every kilogram of peat restrains potassium dihydrogen phosphate (KH with addition of 3-5

Preparation method of the present invention is: press formula rate with the ureaformaldehyde slow release fertilizer, potassium dihydrogen phosphate, polypropylene acid type water-loss reducer, with polyvinyl alcohol (PVA)-lignin type adhesive, the indolebutyric acid root-growing agent, perlite mixes more than 10 minutes by mixer, enter the pulverizer pulverizing and be prepared into nutrition accessory, the particle of crossing 1 mm sieve accounts for total material more than 70%; To mix at mixer with nutrition accessory through the peat of pulverization process and enter the make-up machine briquet more than 20 minutes.
The specification of peat culture can be: profile is a cylinder, high 10-15 centimetre, and diameter 8-10 centimetre; It is conical planting the hole, and the degree of depth is 5-8 centimetre, and diameter is 2 centimetres.
Using method of the present invention: the peat culture is placed on the level land, 2-3 centimetre at interval of every peat body, with watering can slowly water spray wetting after, vegetable seeds or seedling are broadcast kind hole into culture, daily management gets final product.After treating that the plant root dish is connected on around the peat body, transplant to contaminated soil and repair.
The present invention has following advantage:
1 the present invention cultivated by the seedling stage of peat culture, the root system of plant prosperity, and the district provides protective layer for plant roots, helps plant resistance to environment stress and strengthens, and improves survival rate and the speed of growth of plant at contaminated soil;
2 contaminated soil methods of the present invention can be according to the characteristics of different soils type, and weather conditions, and the vegetation of IA selects plant to plant flexibly;
It is organic mineral resources of natural cleaning that 3 the present invention adopt peat, can not cause secondary pollution;
