Background art:
malignant events caused by the problem of heavy metal contaminated soil are frequent all over the world, which has caused high vigilance of human society, and the research and development of various technologies for preventing and repairing the heavy metal contaminated soil become hot spots of concern in all circles. The heavy metal cadmium pollution is one of the most common heavy metal pollution, the chemical activity of the cadmium element in each heavy metal element is stronger, the cadmium element is more easily absorbed by plants and stays in edible parts of the plants, and finally the cadmium element is enriched in a human body through diet, and the excessive heavy metal cadmium can cause diseases such as bone pain and the like which are harmful to human health.
In recent years, a method for restoring soil polluted by heavy metal by using heavy metal hyperaccumulator plants is gradually paid attention, and the plant restoring method has the advantages of in-situ restoration, low cost, wide adaptability and no secondary pollutants, and has the effects of protecting surface soil, restoring landscape, improving soil property and reducing water and soil loss after vegetation is formed. Super accumulator plants can super-absorb heavy metal and move it to the plant that the ground position carries out the accumulation, and super accumulator plants overground part's heavy metal volume of accumulating can reach about 100 times of non-super accumulator plants overground part, and heavy metal super accumulator plants still flourish in heavy metal pollution ground growth in addition, and the biomass is big, can normally accomplish the life history.
The heavy metal hyper accumulation plant is repairing contaminated soil's weak point is, the amount that the plant absorbs soil heavy metal is relevant with the heavy metal content in the soil, heavy metal concentration is higher in the soil around the root system and then the plant absorbs heavy metal more, most of the hyper accumulation plant roots are shallow, the root system coverage area is little, therefore the total amount of the heavy metal element that traditional hyper accumulation plant enriched is little, it is inefficient to clear away heavy metal, need plant many times, need consume a large amount of time like this and can make soil heavy metal content reach harmless requirement, this has also improved the cost that the plant method cleared away soil heavy metal. Therefore, the adsorption range of the heavy metal super-accumulation plant root system is more effectively expanded, and the enrichment efficiency of the plant on the soil heavy metal is improved.
The utility model has the following contents:
the problem that provides for solving above-mentioned background, the utility model provides a get rid of capsule seed of heavy metal cadmium in soil, this capsule seed can effectively adsorb heavy metal cadmium ion in the soil to plant roots around, extend plant roots to the adsorption band of soil, make the seed accomplish soil heavy metal concentration around the life history in-process root relatively high, make the plant can adsorb heavy metal in more soil. The utility model discloses simple structure, convenient to use, it is efficient to clear away of soil heavy metal, practiced thrift the cost that the plant law was managed heavy metal contaminated soil relatively.
The utility model discloses a technical scheme who solves technical problem and adopt is: the coated seed for removing heavy metal cadmium in soil is characterized by comprising a sedum alfredii seed (1) positioned at the core, a water-absorbing medicine film (2) of an insecticide compound bactericide is coated on the outer surface of the sedum alfredii seed, a slow-release fertilizer layer (3) containing nitrogen, phosphorus and potassium nutrient elements is coated on the surface of the water-absorbing medicine film of the insecticide compound bactericide, a heavy metal adsorption layer (4) containing a lignin-montmorillonite compound is coated on the surface of the slow-release fertilizer layer containing the nitrogen, phosphorus and potassium nutrient elements, and a cylindrical budding hollow pore channel (5) is communicated to the coated seed core from the outer surface of the coated seed.

The coated seed for removing the heavy metal cadmium in the soil is characterized in that the thickness of the heavy metal adsorption layer (4) containing the lignin-montmorillonite compound is 0.5-2.0 cm.
The coated seed for removing the heavy metal cadmium in the soil is characterized in that the diameter of a cylindrical budding hollow pore canal (5) penetrating from the outer surface of the coated seed to the core of the coated seed is 0.1-0.5 cm.
The beneficial effects produced by adopting the technical scheme are as follows:
a get rid of capsule seed of heavy metal cadmium in soil, included southeast common stonecrop herb seed (1) that is located capsule seed core, southeast common stonecrop herb has perennial, vegetative propagation, the biomass is great and is suitable for the plant of cutting, simultaneously, its strong adaptability, resistant adverse habitat such as barren, arid and highlight, the sight is strong, is the good plant of implementing phytoremediation and ecological greening. The sedum alfredii has strong tolerance capability and super accumulation characteristics on excessive cadmium, zinc and lead in soil, and particularly can absorb heavy metal cadmium to the overground part of a plant, so that the heavy metal pollution of the soil is effectively reduced. In order to improve the germination and survival rate of the coated seeds, the utility model discloses a contain not only one in the coated seeds, but a plurality of southeast sedum seeds.
A get rid of capsule seed of heavy metal cadmium in soil, at south of the east sedum seed surface cladding one deck insecticide composite fungicide absorb water medicine membrane (2), this layer absorbs water medicine membrane can absorb the moisture in the soil, provides the water source for the seed sprouts. In addition, the water-absorbing pesticide film also contains pesticide and bactericide, and can effectively prevent the seeds from being damaged by harmful bacteria and diseases and insects in the early stages of germination and growth.
A get rid of capsule seed of heavy metal cadmium in soil, the absorbent membrane surface cladding one deck nitrogenous phosphorus potassium nutritive element's of insecticide compound fungicide slow release fertilizer layer (3), this is in order in the growth phase after the seed sprouts, can provide the required nutrient composition of vegetation of capacity for the seed, slow release fertilizer is according to vegetation's different stages, with the slow release of the fertilizer molecule that the plant needs, can utilize the fertilizer molecule more effectively, promote vegetation.
A get rid of capsule seed of heavy metal cadmium in soil, contain heavy metal adsorption layer (4) that lignin-montmorillonite complex is contained to the one deck at slow-release fertilizer layer (3) surface cladding that contains nitrogen phosphorus potassium nutrient element, contain a large amount of hydroxyl groups in the lignin molecular structure, can adsorb the heavy metal ion in the soil, the montmorillonite has layered structure, the inorganic plywood of montmorillonite area negative charge can adsorb the heavy metal ion cadmium of taking positive charge in the soil. The lignin-montmorillonite composite has a layer-embedded structure and a large specific surface area, improves the adsorption capacity of montmorillonite to heavy metals, is easier to form compared with a montmorillonite raw material, and has higher mechanical strength and difficult pulverization under the dry condition, so that a coating layer can not be damaged when coated seeds are transported and sowed.
