Description
Technical field
The present invention relates to technical field of fertilizers is and in particular to a kind of fertilizer for phthalic acid ester contaminated soil.
Background technology
Phthalic acid ester, PAEs, also known as phthalate ester, it is commonly called as plasticiser, be the important organic compound of a class, their quilts
It is widely used as the raw materials for production of plastic plasticizer, farm chemical carrier, anthelmintic, clothing, cosmetics, lubricant etc..Wherein consumption is
Big is plastic plasticizer, accounts for the 80% of its total output.PAEs is also a class environment incretion interferent, and have has reproduction
Development toxicity, hepatotoxicity and potential carcinogenecity and bioaccumulation effect, wherein 6 kinds PAEs compounds are supervised by Chinese environmental
Survey master station, American National Environmental Protection Agency and European Union etc. and be classified as " excellent control pollutant ".In recent years, the making in a large number in the industry with PAEs
With the extensive application with covering with ground sheeting (inclusion hot house) cultivation technique, in agricultural soil, the pollution of PAEs is universal.China's work
Farming region soil all suffers from PAEs to be affected in various degree, content typically in micro- g kg to the mg/kg order of magnitude, with dirt
Irrigated area and industrial occupancy soil pollution are more serious.Content in soil for the PAEs is far above polycyclic aromatic hydrocarbon, Polychlorinated biphenyls etc. persistently
Property organic pollution, oneself becomes the global important environmental organic pollutant of a class at present.Hydrophobicity and anti-fall due to PAEs
Solution ability is strong, easily causes its enrichment in the environment, this certainly will have influence on the safety planting the crops on this Polluted Soil,
The harm mankind's is healthy.Both at home and abroad the recovery technique of the organic polluted soils such as Organic substance and polycyclic aromatic hydrocarbon is carried out in a large number
Research, but the improvement to PAEs contaminated soil is relative with recovery technique research little.General contaminated soil can adopt physico
Learn and repair and biological restoration two big class method.Physical chemistry reparation includes heavy metal pollution of soil, chemical fixation, electro reclamation, Soil leaching
Deng these technology are not only very expensive, be difficult to administer on a large scale, and can lead to Soil structure destruction and fertility declines etc..At present,
Both at home and abroad biological renovation method, especially microorganism remediation are mainly adopted to PAEs contaminated soil.Mainly pass through screening micro-
Biological inoculum, removes PAEs in soil using efficient degradation PAEs strain.Microorganism remediation is related to the screening of efficient degrading bacteria,
And by such inoculation in PAEs contaminated soil, after this technology cycle is relatively long, and degradation bacteria is inoculated in soil
The removal effect in difficult to reach laboratory by impacts such as a lot of environmental factorss.Therefore to the improvement of PAEs contaminated soil and
Repair, be very urgent task.Through research, the pollution condition improving P in soil AEs by the administration of fertilizer is current cost
Cheap, reparation situation is controlled, meets the new processing method of environmental friendliness development, and therefore, a kind of low cost of exploitation, environment are friendly
Novel farmland fertilizer that is good, can efficiently alleviating soil contamination problem, had both enabled crop yield, and also can effectively repair PAEs to soil
The pollution that earth brings, reduces its content in soil, China's agricultural development and fertilizer field is had great significance and compels
Cutting property.

Experimental example
In order to further illustrate the using value of the present invention, inventor have chosen the water of 6 pieces of phthalate pollutions
Rice experimental plot, one of during rice cultivation using common fertilizer as a control group, implemented using the present invention respectively for another 5 pieces
The fertilizer of example 1～5 as experimental group, after testing, in the phthalate content on 6 pieces of ground, double (the 2- ethyl of phthalic acid
Hexyl) ester average content in 45.2mg/kg, the average content of the positive dibutyl ester of phthalic acid is 77.6mg/kg, during plantation
Sampling analyses are carried out to the phthalate of 6 blocks of soil, is counted in conjunction with rice yield, result is as shown in table 1：
Table 1
Explanation：To phthalic acid in soil, double (2- ethylhexyl) ester removal efficiencies reach more than 97.4% to the present invention, right
In soil, phthalic acid positive dibutyl ester removal efficiency reaches more than 97.6%, and effect is significant also has abundant nutrition, with Oryza sativa L.
As a example, be effectively promoted the growth of Oryza sativa L., per mu yield, with respect to matched group, can increase production 13.1～13.9%, realize high yield and
The double benefit of removing Organic substance.
