Description
Technical field
The present invention relates to technical field of fertilizers, and in particular to a kind of fertilizer of reduction Fructus Fragariae Ananssae heavy metal pollution.
Background technology
With economic fast development and the progress of industrial technology, the harmful effect of work, agricultural production to environment constantly adds
Play, because solid waste is constantly stacked and toppled over to soil surface, harmful waste water constantly permeates in soil, harmful in air
Gas and floating dust are also constantly dropped in soil with rainwater, result in soil pollution.Wherein, heavy metal pollution of soil has become not
Hold the prominent environmental problem ignored, heavy metal is enriched with soil camber, deteriorates soil environment quality, affects the yield of agriculture Fructus Fragariae Ananssae
And quality, the ecological circulation of serious harm soil, it passes through food chain and enters human body, endangers the healthy of people, threatens people
The living environment of class, heavy metal pollution can not only cause the change of composition of the soil, 26S Proteasome Structure and Function, additionally it is possible to suppress Fructus Fragariae Ananssae
Root growth and photosynthesis, cause the Fructus Fragariae Ananssae underproduction even to be had no harvest, it is even more important that heavy metal is also possible to be moved by food chain

Experimental example
In order to further illustrate the using value of the present invention, inventor have chosen the Fructus Fragariae Ananssae experimental plot of 6 pieces of heavy metal pollution,
One of to use common fertilizer as a control group during plantation Fructus Fragariae Ananssae, another 5 pieces respectively using the embodiment of the present invention 1～5
Used as experimental group, after testing, total copper content meansigma methodss on 6 pieces of ground are 1.52mg/kg to fertilizer, and total Zn content meansigma methodss are
3.23mg/kg, total copper of total nickel content meansigma methodss during 279.5mg/kg, plantation to 6 blocks of soil, total zinc, total nickel content are entered
Row sampling analyses, are counted with reference to Yield of Strawberry, as a result as shown in table 1, and total copper, total zinc, total nickel of the Fructus Fragariae Ananssae to 6 pieces of products
Content is measured, as a result as shown in table 2：
Table 1
Explanation：The present invention can effectively reduce the activity of metal ion in soil, change form of the heavy metal in soil, will
Heavy metal in soil is changed into soil from available state and/or crop is difficult to the invalid state that absorbs, reduces the suction of crop heavy metal
Receive, so as to reach the purpose of repairing heavy metal in soil pollution, the number turnover of invalid state is changed into as soil remediation with available state
Judging quota, the present invention reaches 92.96～93.09% to the conversion ratio of soil copper metal, and the present invention turns to zinc in soil metal
Rate reaches 92.47～92.53%, and the present invention reaches 91.5～91.6% to the conversion ratio of soil nickel metal, the fertilizer of the present invention
Not only heavy metal repairing effect significantly, also with abundant nutrition, effectively facilitates the growth of crop, by taking Fructus Fragariae Ananssae as an example, per mu yield to material
Amount can increase production 9.3～10% relative to matched group, realize the double benefit of high yield and repairing heavy metal in soil.
Table 2
Explanation：Can be seen that from upper table, using the fertilizer of the present invention, compared with conventional fertilizers, after maturation in strawberry fruit
The content of heavy metal copper reduces 66.7～71.1%, and Zn content reduces 52.8～58.3%, and nickel content reduces 64.7～
67.6%, it is ensured that the edible safety of Fructus Fragariae Ananssae, strawberry fruit mouthfeel and outward appearance are improved to some extent, and are meeting nothing
Also very big economic benefit is brought while public hazards, green and organic food standards for peasant.
