Description
Technical field
The present invention relates to technical field of soil remediation, and in particular to a kind of microorganism agricultural land soil renovation agent and its reparation side
Method.
Background technology
The mankind multiply and live on soil for generations, are provided by being cultivated on soil to obtain endlessly existence
Source.At present, chemical fertilizer and pesticide are used in large quantities in order to increase production and improve productivity in farmland, cause heavy metal in soil content exceeded,
Soil hardening is serious, and eventually leading to crop production reduction can not even grow.Soil receives the pollution of heavy metal, the agriculture of cultivation
Field soil environment is gradually deteriorated.Heavy metal can be finally enriched to by food chain in mankind's body, to the health band of eater
Carry out security risk.The pollution of cultivated soil and the underproduction of grain all hinder the development of agriculture health, it is therefore desirable to effective and feasible
Soil remediation method.
The administering method of farmland soil heavy metals pollution spatially has in-situ immobilization and showering to divide, by processing method
There are engineering measure, chemical measure, microorganism measure to divide.Soil remediation method cuts both ways：Showering compares more thoroughly but grasps
Make difficulty it is big, it is with high costs and be not suitable for large area farmland reparation.Engineering measure is digged including heavy metal pollution of soil, soil replacement method, deep ploughing
Method, curing, stabilization method, Electroremediation method etc., engineering measure have the advantages that stablize, are quick, but there are quantities
Greatly, the shortcomings of investment cost height, secondary pollution hidden danger, it is not suitable for the improvement of pollution in wide area soil.Chemical harnessing measure includes
Leaching method, using modifying agent the methods of, can reduce the toxicity and biological effectiveness of heavy metal in soil in a short time, but because
Artificial applies chemical agent into soil, and chemical agent excessively launches the secondary pollution for easily causing soil.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of microorganism agricultural land soil renovation agent and its restorative procedure, to solve agriculture

The present invention also provides a kind of method that soil remediation is carried out using mentioned microorganism agricultural land soil renovation agent, the sides
After the acquisition of method including pedotheque and detection, the ingredient allotment of soil-repairing agent, the using and use of soil-repairing agent
Native condition is kept, and is specifically carried out in the steps below：
Step 1 acquires pedotheque and detects heavy metal component and activated state content (referring to table 3)；Specifically, it utilizes
Cutting ring formula original-state soil sampler layouts method acquisition pedotheque (using snake if greenhouse is more long and narrow using checkerboard type
Shape is layouted method), 5/mu of pedotheque quantity (increases and decreases) in proportion according to real area, and acquisition utilizes GB15618- after completing
1995 methods detection content of beary metal (testing agency can be transferred to detect)；
Step 2, the detection data provided according to table 3 targetedly match soil-repairing agent (Examples 1 to 4, proportioning
Refer to table 1)；
Step 3 measures soil moisture content, and by water content control 30%~50%.If moisture deficit needs to water
Moisturizing.
Step 4 is normal by crops by the organic fertilizer of fowl and animal excrement (fowl and animal excrement can be chicken manure, sheep manure, cow dung etc.)
Growth aequum is uniformly applied in pending soil surface, pending soil table will be sprayed at after soil remediation dilution agent
Layer completes later plowed soils immediately, ploughed depth 20cm~40cm；Soil-repairing agent makes to be diluted with water, and ratio 1: 80~
100。
Step 5, after Soil tillage is completed, by temperature control at 20 DEG C~40 DEG C, canopy film lowering is kept for earthing heat preservation
Anaerobic environment in greenhouse, soil enter repair process.If the processing time is summer, timing is needed to open canopy mouth aeration-cooling.Institute
It states Step 3: step 4 and step 5 needs were completed in 24 hours.After soil-repairing agent, 5~8 days are microorganism soil
During which the reparation phase of earth renovation agent cannot carry out farming operations and must not use any fertilizer and pesticide.Soil is repaired according to current
The data that earth obtains, renovation agent are covered on the soil repaired, and dosage is 10~30L per acre.Renovation agent used in amounts
It to be set according to the amount of organic fertilizer.Each ton of organic fertilizer averagely matches 10L bacterium solutions.
It should be noted that microorganism agricultural land soil renovation agent provided by the invention is only capable of and using fowl and animal excrement class as raw material
Organic fertilizer be used cooperatively.
Examples 1 to 4 is the experiment that inventor carries out in Qingzhou City village of Shandong Province, and local farmers due to largely making for a long time
With fertilizer and pesticide so that heavy metal pollution of soil problem is very prominent, has seriously affected the income of local farmers, has limited locality
The development of agricultural.The method that we use check experiment in locality compared traditional mode with using at two kinds of soil-repairing agent
By the time (5~6 months or so) of sharp one Growing season of green pepper under reason mode, the variation before and after heavy metal content in soil.
It is as shown in table 1 below by after extracting pedotheque and measuring its content of beary metal, preparing renovation agent：
The component proportion of 1 Examples 1 to 4 of table
When carrying out soil remediation construction, the soil remediation response parameter of Examples 1 to 4 is as shown in table 2 below：
2 soil remediation response parameter of table
Table 3：The forward and backward each contents of heavy metal elements variation of control group processing
Brief summary：
As can be seen from Table 3, traditional planting patterns is due to the use of chemical fertilizer, and heavy metal pollution of soil is serious after harvesting.Make
Soil remediation is carried out with microorganism renovation agent provided by the invention, and the different degrees of reduction of the heavy metal in soil, explanation is matched
Close a kind of microorganism agricultural land soil renovation agent of present invention offer has apparent inhibiting effect to activated state content of beary metal in soil.
Based on above-described embodiment 1~4, a kind of microorganism agricultural land soil renovation agent provided by the invention, contaminated soil sampling
Science, proportioning is reasonable, and method is effective.Active ingredient in soil-repairing agent can targetedly in curing soil activated state
Heavy metal, reduces its toxic action to crops, and the growth for crops provides good environment, has a extensive future.
The foregoing is merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto,
The change or replacement that any one skilled in the art is expected in the technical scope disclosed by the present invention should all be contained
Lid is within protection scope of the present invention.
