Description
Technical field
The present invention relates to Rice Cropping, specifically a kind of method in cadmium pollution soil safety in production rice.
Background technique
Cadmium (Cd) is human body non-essential element, bio-toxicity extremely strong (Chen Lang, Song Yufang etc.: " Cadmium Pollution in Soils poisonous effect
Multiple attribute synthetical evaluation ", " environmental science ", 2008,29 [9]), half-life period in human body for 20~40 years, can draw
" Itai-itai diseases ", renal damage etc. (Chen Yingxu, " environmentology ", China Environmental Science Press, 2005) are sent out, are planned in united nations environment
First place is occupied in 12 kinds of dangerous chemicals with global meaning that administration proposes.By increasingly developed mining, smelting, plating
It is increasingly severe with industry and influence from agricultural input product itself, the agricultural land soil cadmium pollution form such as printing and dyeing.Public affairs in 2014
The national Soil Pollution Investigation bulletin of cloth shows that cadmium ranks inorganic pollution first place, wherein arable soil point exceeding standard rate
It is 19.4%, is concentrated mainly on mild or moderate pollution (" national Soil Pollution Investigation bulletin ", 2014).And rice has been found
To absorb one of strongest large cereal crops of cadmium ability, therefore, arable land cadmium pollution has seriously threatened the grain quality to China
Safety.The food chain pipeline for how effectively blocking heavy metal contaminants is always the hot spot of scientific circles' research.Food chain passes
Passing is that the heavy metals such as cadmium enter one of important channel of human body, and the World Health Organization suggests that the cadmium amount taken in for each person every day should not surpass
Cross 68 μ g.
For rice as a kind of staple food, quality safety is particularly important.And the clean manufacturing of rice depends on good soil
Environmental quality.The production new in face of Rice Production needs the severe situation of situation and current soil toxic heavy metal contamination, produces toxic
Accumulation of heavy metals amount is lower than the safe rice of AMV, is to realize that rice farmer increases income, growth of agricultural efficiency and ensures one of people's health
Important channel.The height that toxic heavy metal accumulates in rice is the knot of the combined factors such as soil climate and agronomic measures effect
Fruit.Therefore, how to select and develop optimization, most economical, most effective soil remediation method is always to perplex art technology
The technical problem of personnel.
Summary of the invention
The purpose of the present invention is to provide a kind of firm cadmium pollution and permanently reduce cadmium element, cadmium pollution soil in soil
The method of safety in production rice, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A method of in cadmium pollution soil safety in production rice, the specific method is as follows:
(1) the cadmium pollution soil surface for treating sowing sprinkles white lime and carries out ph balancing adjustment 15-20 days；PH value
Ploughing soil is carried out after the completion of balanced adjustment, and sprinkles heavy metal soil-repairing agent on the soil for turn over completion；
(2) 5-7 days before rice seedling transplanting, base manure manually is administered to cadmium pollution rice field and rice field is divided
Area；Subregion is to be divided into the paddy fields being staggered and absorption cadmium element crop growing spots；
(3) plantation of rice seedling is carried out in paddy fields, and is buried under the soil for absorbing cadmium element crop growing spots
Enter the seed of leaf bud south mustard；
(4) drowned rice field measure is carried out in rice milking stage key developmental stages, while also carries out a top dressing, soil surface water
Layer depth is 4-5cm, floods leaf bud south mustard plant as far as possible, so that growth of the leaf bud south mustard in the rice milking stage stage is pressed down
System, water oxygen level is few, and leaf bud south mustard seedling can obtain sufficient illumination when rice plant is shorter with quick
Production, and until rice plant grows tall and cooperates water logging, enables to sunlight and oxygen supply to receive influences, to inhibit to produce and dead
It dies；
(5) the leaf bud south mustard plant absorbed in cadmium element crop growing spots manually is cleaned up with rake, and by leaf bud south mustard
Plant centralized collection transports rice field region and carries out burning recycling cadmium element processing；
(6) until after the completion of rice harvesting, the stalk of rice cannot be stayed in field, while be also required to carry out burning recycling
Processing.
As a further solution of the present invention: the dosage of white lime is 8-10kg per acre, huge sum of money dependent territory in the step (1)

The width of cadmium element crop growing spots is 10-15cm.
As a further solution of the present invention: paddy fields and absorption cadmium element crop growing spots in the step (2)
Partitioning scheme be that artificial bracing wire is split, the both ends of line are scheduled on the stalk of rice field by wood chock.
As a further solution of the present invention: being imposed in the step (4) with the drowned rice field time is 4 weeks before rice milking stage
And after grouting between 4 weeks.
As a further solution of the present invention: organic fertilizer, organic fertilizer being applied to field after the completion of harvesting in the step (6)
Usage amount is 40-50kg per acre, and for keeping land fertility to avoid hardened, while organic fertilizer is more advantageous to and is polluted by cadmium element
Rice field in microbial flora recovery.
Compared with prior art, the beneficial effects of the present invention are:
The present invention consolidates cadmium pollution by the way of cadmium element sedimentation in cadmium pollution, avoids further with Rice Cropping
Irrigation water in production process expands pollution；Interval plantation is carried out in rice field using the plant that can absorb cadmium element simultaneously,
And to stalk and absorb the recovery processing of cadmium element crop and thoroughly to reduce the content of cadmium element in soil, i.e., by stablize with
Shunting mode administers the cadmium element in rice field, and the rapid determination of content of cadmium element in rice product is effectively reduced；
In addition by the way of changing soil pH value and the mode of sedimentation reduces absorption of the rice to cadmium element, so that
Cadmium element in rice is reduced within safety value range.
