The invention discloses a kind of methods for administering cadmium pollution soil using corn and black nightshade, the following steps are included: S1, soil cadmium content be 1-5mg/kg In Cadmium Polluted Area carry out Soil tillage, then according to 800-1200kg/ mus of applicationss of farmyard manure and 15-30kg/ mus of application physiological alkaline fertilizers, soil pH is made to reach 7-8.5；S2, in the soil according to 3000-5000 plants/acre density maize planting and interplant black nightshade；S3, its aerial part, toothing 3-5cm, the black nightshade aerial part centralized processing of harvesting are gathered in after black nightshade plant strain growth to 30-40cm height；S4, S3 step is repeated until harvest corn, black nightshade plant of then rooting out focuses on.Method of the invention may be implemented to repair in production, and completely remove the cadmium pollution in soil, and there is no pollute again.
Description
Technical field
The present invention relates to heavy metal soil remediation fields, administer cadmium pollution soil using corn and black nightshade more particularly, to a kind of
The method of earth.
Background technique
Heavy metal cadmium is one of the heavy metal element of soil environment heavy metal pollution, and excessive cadmium can be in plant in the soil
In vivo residual, when Cd accumulation to a certain extent when, plant will show poisoning symptom.Cadmium in soil can also pass through food chain
Enrichment enter human body, have stronger carcinogenic, teratogenesis and mutagenesis to human body.Therefore, for the improvement of cadmium pollution soil
There is very important meaning in environment protection field.
Although there are many technology that can be used for restoration of soil polluted by heavy metal, such as peripheral doses, chemical remediation, phytoremediation
Deng, but various recovery techniques have the limitation of its own, and China human mortality is numerous, the demand to grain is huge, big
In area, in slight pollution farmland carry out phytoremediation and stop plant crops it is clearly impossible.It is low in
On contaminated soil, screen and identify low heavy metal accumulation crop with more can in sufficient crop or crop varieties from currently depositing extensively
Row and operability.The screening and evaluation program of low accumulation crop are simple and easy, do not have ecological risk, and the low product screened
Tired crop can directly promote and apply in locality.
Summary of the invention
The purpose of the present invention is to drawbacks described above and provides and a kind of administer cadmium pollution soil using corn and black nightshade
Method.
The method for administering cadmium pollution soil using corn and black nightshade of the invention, comprising the following steps: the following steps are included:
S1, Soil tillage is carried out in the In Cadmium Polluted Area that soil cadmium content is 1-5mg/kg, is then applied according to 800-1200kg/ mus
Farmyard manure and 15-30kg/ mus of application physiological alkaline fertilizers, make soil pH reach 7-8.5；
S2, in the soil according to 3000-5000 plants/acre density maize planting and interplant black nightshade；
S3, its aerial part, toothing 3-5cm, the black nightshade overground part of harvesting are gathered in after black nightshade plant strain growth to 30-40cm height
Divide centralized processing；
S4, S3 step is repeated until harvest corn, black nightshade plant of then rooting out focuses on.
Corn variety is one or more of lucky Hunan 2133, Ji list 7, long jade 13, honest jade 518 in S2.
Corn and black nightshade are sowed simultaneously in the interplanting step of S3, and corn uses drilling, and black nightshade uses and broadcasts sowing.
The centralized processing of S3 and S4 is after black nightshade is dried and is ashed as solid waste landfill disposal.
Physiological alkaline fertilizer is one of calcium nitrate, potassium carbonate, sodium nitrate or a variety of is made in S1.
The present invention mainly selects low heavy metal accumulation corn variety, can plant in In Cadmium Polluted Area and meet food safety quality mark
Quasi- cereal crops；The super enriching plant black nightshade that the present invention selects have growth cycle it is short, it is strong to cadmium accumulation ability, biomass compared with
Greatly, become the good material of phytoremediation application；It may be implemented to repair in production, and completely remove the cadmium pollution in soil,
There is no pollute again.
Specific embodiment
Below in conjunction with the embodiment of the present invention, present invention is further described in detail.
Embodiment
One piece of 600m is chosen near the mining area of Jingmen City, Hubei Province2Farmland is as experimental plot, through detecting soil cadmium content
For 3.524mg/kg, referring to standard of soil environment quality GB 15618-1995 secondary standard, exceeded 2 times of cadmium content, pollution depth
25cm；
S1, Soil tillage is carried out in experimental plot, then according to 800-1200kg/ mus of applicationss of farmyard manure and 15-30kg/ mus of application lifes
Alkaline fertilizer is managed, soil pH is made to reach 7-8.5；
S2, in the soil according to 3000-5000 plants/acre density maize planting and interplant black nightshade；
S3, its aerial part, toothing 3-5cm, the black nightshade overground part of harvesting are gathered in after black nightshade plant strain growth to 30-40cm height
Divide centralized processing；
S4, S3 step is repeated until harvest corn, black nightshade plant of then rooting out focuses on.
Corn variety is one or more of lucky Hunan 2133, Ji list 7, long jade 13, honest jade 518 in S2.
Corn and black nightshade are sowed simultaneously in the interplanting step of S3, and corn uses drilling, and black nightshade uses and broadcasts sowing.
The centralized processing of S3 and S4 is after black nightshade is dried and is ashed as solid waste landfill disposal.
Physiological alkaline fertilizer is one of calcium nitrate, potassium carbonate, sodium nitrate or a variety of is made in S1.
Analyzed by table 1 it is found that in corn kernel cadmium content meet " national forage health standard " (GB 13078-2001) and
" national food safety standard pollutants in food limitation " (GB 2762-2017) is the agricultural product with economic value.It passes through simultaneously
Detecting soil soil cadmium content after maize planting and black nightshade reduces about 3/4ths, this shows that method of the invention makes cadmium dirty
Dye soil is repaired well, while the corn produced meets national food safety standard.
Table 1 screens heavy metal cadmium content in the yield and niblet of each corn variety
Comparative test
One piece of 600m is chosen near the mining area of Jingmen City, Hubei Province2As experimental plot, being detected soil cadmium content is in farmland
3.416mg/kg(and embodiment are similar), referring to standard of soil environment quality GB 15618-1995 secondary standard, cadmium content is super
Nearly 2 times of tag splice, pollution depth 25cm；
S1, Soil tillage is carried out in experimental plot, then according to 800-1200kg/ mus of applicationss of farmyard manure and 15-30kg/ mus of application lifes
Alkaline fertilizer is managed, soil pH is made to reach 7-8.5；
S2, in the soil according to 3000-5000 plants/acre of density maize planting, corn is using drilling until harvest corn.
Corn variety is one or more of lucky Hunan 2133, Ji list 7, long jade 13, honest jade 518 in S2.
Table 2 screens each corn variety and does not interplant heavy metal cadmium content in the yield and niblet of black nightshade
It is analyzed by table 2 it is found that in tested 4 corn varieties, cadmium in Ji Xiang 2133, Ji single No. 7 and honest beautiful 518 corn kernels
Content meets " national forage health standard " (GB 13078-2001) and " national food safety standard pollutants in food limitation "
(GB 2762-2017) grows cadmium content in the niblet of jade 13 and does not meet " national food safety standard pollutants in food limitation "
(GB 2762-2017), but reached " national forage health standard " (GB 13078-2001).
The above-mentioned only present invention preferably feasible embodiment, the non-therefore limitation scope of the present invention, according to above-mentioned reality
It applies the made various modifications of example or applies within this technical solution protection scope.
