Description
Technical field
The invention belongs to soil improvement field, specifically a kind of method for reducing pakchoi and absorbing heavy metal nickel.
Background technology
Soil is the valuable source of human social development, carries in environment 50%~90% pollutional load.Heavy metal
It is typical pollutant present in soil, there is the features such as chronicity, disguise, cumulative bad.Heavy metal in agricultural land soil is rich
Crop yield and quality, and the serious threat ecosystem and human security can be not only reduced when collecting to a certain extent.In order to
Man and nature safety, harmonious, sustainable development, it is imperative that heavy metal pollution of soil is repaired.
Heavy metal pollution is always the environment and health problem that the mankind pay close attention to.Wherein heavy metal nickel is needed by human
Biological element, there are many important biological functions.But excessive nickel enters in human body and body will be produced to a certain degree
Toxic action.Once the liver and cardio-pulmonary function of the exceeded healthy instructions nickel infringement people that will endanger people, cause serious
Dermatitis and allergic.In recent years, the environmental pollution as caused by nickel and its compound is increasingly severe.Nickel ore smelting stone, nickel plating
The enrichment of the discharge, nickel of industrial wastewater in soil etc. eventually enters into body effect's human health by food chain.
Pakchoi is a kind of vegetables in original East Asia, is commonly called as green vegetables, and also known as glue dish, savoy, wooden dipper are white, rape is (Chinese
Northeast certain areas), pakchoi etc., be close relative with Chinese cabbage (Chinese cabbage), belong to rape one kind, and the cabbage in west together
Also it is relatively near, belong to Cruciferae Brassica genus together.China is originated in, north and south various regions are distributed, and are cultivated in China quite varied.Little Bai
Dish is Brassica genus (mustard category) cultivated plant, and cauline leaf is edible, one, biennial herb plant, often make annual cultivation.Plant is shorter
It is small, shallow root system, fibrous root prosperity.Leaf color pale green is to blackish green, blade obovate or ellipse, and blade is smooth or pleat contracting, minority have suede
Hair.Petiole is plump, white or green.Not balling.Flower amber seed subcircular.According to surveying and determination, pakchoi is to contain mineral matter in vegetables
The most abundant dish with vitamin.
At present, with addition bamboo charcoal, sepiolite, erionite, cow dung charcoal, litchi rind powder in heavy metal nickel contaminated soil
End reduces pakchoi absorption heavy metal nickel and not yet had been reported that.
The content of the invention：
It is an object of the present invention to provide a kind of method for reducing pakchoi and absorbing heavy metal nickel.
Technical scheme：A kind of method for reducing pakchoi and absorbing heavy metal nickel, it is characterised in that：In heavy metal nickel pollution
Bamboo charcoal, sepiolite, erionite, cow dung charcoal, litchi rind powder are added in soil.The soil pH value of the lead contamination is 4-5,
Total mg/kg of nickel content 135.
In one embodiment, heavy metal nickel contaminated soil 90-95 parts, bamboo charcoal 1-2 parts, sepiolite 2-4 parts, erionite
1-3 parts, cow dung charcoal 0.8-1 parts, litchi rind powder 5-10 parts.
In one embodiment, 90 parts of heavy metal nickel contaminated soil, 1 part of bamboo charcoal, 2 parts of sepiolite, 1 part of erionite, ox
0.8 part of excrement charcoal, 5 parts of litchi rind powder.
In one embodiment, 95 parts of heavy metal nickel contaminated soil, 2 parts of bamboo charcoal, 4 parts of sepiolite, 3 parts of erionite, ox
1 part of excrement charcoal, 10 parts of litchi rind powder.
In one embodiment, 93 parts of heavy metal nickel contaminated soil, 1.5 parts of bamboo charcoal, 3 parts of sepiolite, 2 parts of erionite,
1 part of cow dung charcoal, 8 parts of litchi rind powder.
The present invention has the advantages that：
The present invention can significantly reduce the nickel content of pakchoi root system, blade.There is improving effect to soil.
The present invention is described below using raw material：
Bamboo charcoal, it is a kind of charcoal for being formed through nearly thousand degree of high-temperature firings using 3 years raw above high mountain mao bamboons as raw material.Bamboo charcoal has
There is loose porous structure, its molecule is fine and closely woven porous, and quality is hard.Have very strong adsorption capacity, can purify air, eliminate it is different
Taste, moisture absorption be mould proof, antibacterial expelling parasite.It can be dried absorbing sweat with human contact, promote blood circulation of human body and metabolism, alleviated tired
Labor.After science refines processing, it is widely used in daily life, in environmental protection, bamboo charcoal is good purifying water treating agent,
Bamboo charcoal is placed in water, the foul smell in the harmful chemical and water remained in water can be adsorbed, river course, dirt are administered with bamboo charcoal particle
The improvement of water, particularly municipal sewage, it can not only purify water, moreover it is possible to remove stink, beautify the environment, effect is particularly significant.
Sepiolite is a kind of clay mineral of magnesium silicate containing Shuifu County for having layer chain structure.Orthorhombic system or monoclinic system,
Typically in block, earthy or fibrous agrregate.Color is white, light grey, dull gray, yellowish-brown, rose, bluish-green
Color, fresh face are pearly luster, are earthy gloss after weathering, hardness 2~3,2~2.5g/cm3 of density, have sliding sense and astringent sense,
Viscous tongue.Property is crisp under drying regime, and shrinkage factor is low, and plasticity is good, bigger than surface, and adsorptivity is strong.It is dissolved in hydrochloric acid, light.Sepiolite
Also there is the performances such as decolouring, heat-insulated, insulation, anticorrosive, radioresistance and thermostabilization.Mainly originate in marine deposit-weathering reworked
In mineral deposit；Also come across in hydrothermal solution mineral ore.
Erionite is one kind in numerous zeolite group minerals, is one of several zeolites that content is most in sedimentary rock.To be aqueous
Sodium potassium calcium aluminium silicate mineral.The crystal of erionite is hairy fiber
Cow dung charcoal be put into after plant's cow dung or grassland cow dung are dried be carbonized in smokeless carbonization machine after obtained ox
Excrement charcoal.
Litchi rind is lichee exocarp.Lichee (scientific name:Litchi chinensis Sonn.) SOUTHERN CHINA is originated in, be
Subtropical fruit tree, aiphyllium are high about 10 meters.
