Abstract
The present invention relates to mercury contaminated soil recovery technique field, more particularly to a kind of method of crops reparation farmland mercury contaminated soil, including step：At the beginning of 4 months by the end of March, some pieces of Soil Mercury Pollution farmlands are chosen, choose the early-rice seedlings transplanting of well developed root system, rich water quality management, seeding stage sprinkling microbial inoculum, the harvesting of late July to early August；Early September to early October then, rape seed uproop rape after ripe in farmland；Next year late March selects fine day by ramie transplantation of seedlings on the farmland, harvest head fiber crops, two fiber crops, three fiber crops to mid-April；Circulate operation above-mentioned steps, until mercury content reaches national standard in agricultural land soil.Three kinds of heavy metal mercury such as rice cultivation, rape, ramie have the crops of very strong enrichment to the present invention successively on the farmland of mercury contaminated soil, and promote reparation of the crops to mercury contaminated soil using chemical regulator so that the annual purifying rate of mercury in soils is up to 45%.
Description
Technical field
The invention belongs to mercury contaminated soil recovery technique field, more particularly to a kind of crops repair farmland mercury contaminated soil
Method.
Background technology
Mercury is a kind of element larger to environmental hazard, human body is nonessential, and extensive mankind's activity, leads since industrialization
A large amount of mercury have been caused to be drained into environment.In China, with the continuous improvement of rapid growth and the urbanization of economy, in the whole country
Mercury contaminated soil problem very severe, especially causes serious harm to agricultural land soil, and the survey showed that, mercury contaminated soil pair
Water environment and agricultural product quality constitute notable threat, because the inorganic mercury in agricultural land soil can be in sulfate reducing bacteria or change
The lower conversion toxicity of effect is bigger, the methyl mercury of biological amplification can be produced by food chain, and then can cause the life of mercury
Thing cumulative effect occurs.Therefore, how to solve the problems, such as the reparation of mercury pollution agricultural land soil and contaminated soil, it has also become one ten
Divide urgent task.
At present, mainly there are three kinds for the processing method in mercury contaminated soil farmland：(1) heat treatment technics, that is, mercury is utilized
Volatility heats to contaminated soil, Elemental Mercury in soil is volatilized, although effect is preferable, this method cost of investment
Height, processing equipment somewhat expensive, unsuitable large area use, and mercury evaporates into also a kind of pollution in air；(2) it is in situ solid
Change/stabilization technology, i.e., the mercury in soil is passivated using chemical substance, reduces its mobility in soil, this method
Though simple, the mercury in soil does not remove, if condition changes, is possible to be released again by fixed pollutant；(3) it is biological
Recovery technique, i.e., using the mercury in plant absorption and Enriching soil, the purpose of purification soil, this method green ring are reached with this
Protect, more adapt to the requirement of environmental protection, increasingly paid attention to by national governments.Therefore, develop one kind and repair agriculture using crops
The method of field mercury contaminated soil is particularly important.
The content of the invention
Three kinds of heavy metal mercury such as rice cultivation, rape, ramie have the present invention successively on the farmland of mercury contaminated soil
The crops of very strong enrichment, and apply chemical regulator and promote reparation of the crops to mercury contaminated soil so that in soil
The annual purifying rate of mercury is up to 45%, suitable for vast heavy metal Hg contaminated soil.
The invention provides a kind of method that crops repair farmland mercury contaminated soil, comprise the following steps：
S1：At the beginning of 4 months by the end of March, some pieces of Soil Mercury Pollution farmlands are chosen, every piece of farmland sets plantation block and gutter, plantation
Block and distance between drains distribution, choose the rice seedling transplanting of well developed root system, seeding stage sprinkling microbial inoculum, conventional field fertilizer
Water management, the harvesting of late July to early August；The microbial inoculum is Friedlander's bacillus zymotic fluid, more viscous class brood cell's bar
What fermented liquid was mixed to get.
S2：Early September to early October then, the farmland in S1 is subjected to draining, loosened the soil, and apply chemical regulation
Agent Na2S2O3；Rape seed presses solid-to-liquid ratio 1:8 are mixed with distilled water, obtain seed liquor, and hydrogen peroxide is added into seed liquor, leaching
Being filtered after bubble 10h and obtain seed to be sowed, seed to be sowed is seeded in farmland, sprays bacillus licheniformis liquid every 7~10 days,
Spray 1~2 month altogether, apply 7 kilograms of urea for every mu after rape final singling, uproop rape after rape maturation, by rape straw
Rapeseed dregs of rice after stalk and oil expression shines dry grinding, is sprinkled into farmland, allows its natural degradation.
S3：Next year late March carries out site preparation to the farmland in S2 and applies KI 10kg/ mus, decomposed oil cake to mid-April
150~200kg/ mus, calcium magnesium phosphate 100~150kg/ mus, select fine day and plant ramie transplantation of seedlings on block described, pour and determine root
Water, plant spacing are 1500~2000 plants/acre, farm manure top dressing 2~3 times, respectively in early June, early August, early November
Harvest head fiber crops, two fiber crops, three fiber crops.
S4：Circulate operation S1-S3, until mercury content is reduced to 1.5mg/kg in agricultural land soil, then complete crops pair
The reparation of farmland mercury pollution.
Preferably, calculation is：
The Mercury in Soil year purifying rate=[(agriculture after the preceding farmland mercury content-ramie of proportion of crop planting harvest completely in every piece of farmland
Field mercury content) ÷ 2] the preceding farmland mercury content of ÷ proportion of crop plantings
The total sum ÷ farmlands block number of Mercury in Soil year purifying rate in the farmland of the Mercury in Soil average year purifying rate in farmland=every piece
Preferably, the block number in the farmland is 4 pieces.
Preferably, block 100~200cm of width, gutter 30~60cm of width are planted described in S1；The spacing in the rows of rice seedling
For 15~20cm, 20~30cm of line-spacing.
Preferably, Na described in S22S2O3Dosage in soil is 5~10kg/ mus, and the hydrogen peroxide volumetric concentration is
20%, and dosage is equivalent to the seed liquor cumulative volume 10~15%.
Preferably, the microbial inoculum is that Friedlander's bacillus zymotic fluid, Paenibacillus polymyxa zymotic fluid press body
Product ratio 3:1 is well mixed what is obtained, and Friedlander's bacillus and Paenibacillus polymyxa cell concentration are respectively 108cfu/ml、
106cfu/ml；Using when per 1ml microbial inoculums addition 200ml sterilized waters mixed bacterium dilution, mixed bacterium dilution presses 2L/ mus
Amount sprayed.
Preferably, in S2, when the bacillus licheniformis liquid is applied, 150ml is added in every 0.5ml bacillus licheniformis liquid
Sterilized water, is made bacillus licheniformis dilution, and bacillus licheniformis dilution is sprayed by the amount of 1L/ mus.
Compared with prior art, beneficial effects of the present invention：
The present invention is had very strong on the farmland of mercury contaminated soil using three kinds of heavy metal mercury such as rice, rape, ramies
The mode of the crops of enrichment crop rotation successively, enrichment suction is carried out using different crops to the different shape of mercury in soils
Receive, while crop rotation can keep, recover soil fertility, nutrient in balanced soil, reduction disease pest and weed.In addition, in water
Seed rice sprays microbial inoculum in planting, and promotes the growth of rice root to grow, the suction of rice root heavy metal mercury is improved with this
Receive, all make use of chemical regulator to promote reparation of the crops to mercury contaminated soil in rape, ramie planting, through 2 years wheels
Making circulation causes the annual purifying rate of mercury in soils to be up to 45%, and cost is low, and it is lasting and green to administer.
