Description
Technical field
The invention belongs to farming land heavy metal pollution regulation field, a huge sum of money is repaired in the fortification of plants extraction for being related to specific composition
Belong to the combined governance packet of pollution farming land.
Background technique
For heavy metal pollution farming land soil, more safely and effectively repair mode is phytoremediation, at low cost, secondary dirt
Contaminate it is easily controllable, and vegetation formed after have effects that protect surface soil, reduce corrode, slow down soil erosion and landscape reparation, can
Large-area applications are in heavy metal pollution farming land soil.In phytoremediation field, studies and what application was more is planted so that ultraproduct is tired
Plant extraction technology based on object.Currently, reported accumulation has more than 500, but most of ultraproducts with hyperaccumulative plant kind
Tired plant narrow application range, root system is shallow, and biomass is small, so that the time required for repairing polluted soil is very long.In addition, plant
Enrichment and tolerance are limited, and plant growth is vulnerable to such environmental effects, so needing the habitat characteristics according to each department
Suitable type hyperaccumulative plant of one's native land is selected, and enhancements appropriate is selected to improve hyperaccumulative plant repairing performance, is had with this
Effect makes up the limitation of phytoremediation.Strengthen in hyperaccumulative plant extraction restoration of soil polluted by heavy metal, skill is induced with chelating agent
Art, the research of microbial association technology and application are more, wherein the effect stability of chelating agent, can large area use.So taking
Strengthen super enriching plant extraction with chelating agent induced activation to repair, is the recovery technique that there is long term growth to be worth.
Plant growth needs advantageous ecological environmental condition, and soil texture is good, nutrient supply is sufficient and coordinates, soil is protected
Water is good with nutrient preserving capability, is wherein most important three Xiang Yinsu.The planting plants seed in heavy metal pollution farming land soil, hair
Bud and growth restriction cause germination percentage low with survival rate, and phytomass is few, thus must take soil structure improved addictive appropriate with
Reasonable broadcast application measure.And in large area repair heavy metal pollution farming land, implement soil structure improved addictive, plant step by step
Sowing, broadcast application, are lost a large amount of manpower and material resources.To improve working efficiency, vegetable seeds is improved in heavy metal
Biomass, the increase hyperaccumulative plant extraction absorption huge sum of money for polluting germination percentage and survival rate in farming land soil, increasing plant
The ability of category, is badly in need of the new product of one kind or technology solves problem above.
Summary of the invention
The present invention sowed etc. for broadcast application and seed implement step by step take time and effort, plant extraction recovery technique is applicable in model
The problems such as small is enclosed, a kind of combined governance packet of fortification of plants extraction repairing heavy metal pollution farming land is provided, overcomes previous
Weakness in experience improves planting effect, enhances the ability of plant absorption heavy metal.
The present invention is realized with following technical solution:
The combined governance packet of fortification of plants extraction repairing heavy metal pollution farming land of the present invention is by heavy metallic activation material, plant species
Son, fertilizer and fertile soil are combined.
The heavy metallic activation material is based on the stable chelating agent of activation effect, including artificial synthesized chelating agent and day
Right chelating agent, specifically by EDTA, EDDS, DTPA, EGTA, dimercaptosuccinic acid, ammonium dihydrogen phosphate, tartaric acid, malic acid, apple
Sour sodium, citric acid, sodium citrate, the one or more of thiosulfate compound.
The heavy metallic activation bill of materials alone becomes packet.
The vegetable seeds selects the seed of type hyperaccumulative plant of one's native land, i.e., within the scope of farming land region to be repaired
The native plants kind of heavy metal effect is tired out with ultraproduct.
The vegetable seeds, fertilizer and fertile soil are mixed into packet.
The mass percentage that interior each ingredient is wrapped in the mixing is as follows: vegetable seeds 20%~40%, fertilizer 20%~40% are remaining
Amount is fertile soil, and the sum of mass percentage of each component is 100%.
For example in Southwestern China area, the type heavy metal hyperaccumulative plant of one's native land that can choose and corresponding activated material are such as
Under:
