Description
Technical field
The present invention relates to technical field of fertilizers, and in particular to a kind of multi-functional soil remediation fertilizer.
Background technology
At present, with the development of social economy, the destruction to environment is also increasingly serious, and soil also generates some problems,
Including heavy metal pollution, a series of problems, such as nutrition leak, wherein, heavy metal pollution of soil has turned into the prominent ring that can not be ignored
Border problem, heavy metal is highly enriched in soil, deteriorates soil environment quality, influences the yield and quality of crops, serious danger
The ecological circulation of evil soil, it passes through food chain and enters human body, and harm people's is healthy, threatens the living environment of the mankind,
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 crop root growth and light
Cooperation is used, and causes crop failure even to have no harvest, it is even more important that heavy metal is also possible to move to animal, people by food chain
In vivo, serious harm animal, health, the report of the harm of the heavy metal pollution such as cadmium rice, arsenic poison, blood lead in recent years are shown in not repeatly
It is fresh.So, need to make Pollution In Soil research for this so that soil pollution obtains the comprehensive regulation, for agricultural planting,
It is also during agricultural planting, to administer soil as one of important means for administering soil pollution by improved soil of applying fertilizer
One of major measure that pollution is taken.
Liquid fertilizer is developed so far various types, is broadly divided into liquid nitrogen fertilizer and the major class of liquid compound fertilizer two, liquid nitrogen
Fertilizer has the nitrogen of ammonium state, nitre state and acid amides state, such as ammonate of the ammonate of liquefied ammonia, ammoniacal liquor, ammonium nitrate and ammonia, urea and ammonia,
Liquid compound fertilizer contains two kinds or three kinds of nutrients in N, P, K, to crop yield effect is significant, but due to composition list
One, unitary function in efficient, quick development instantly, is researched and developed a kind of composition and is enriched, multiple functional Liquid Fertilizer, both comprising work
Thing is grown outside necessary nutriment, moreover it is possible to the fertilizer of effective reparation is carried out to heavy metal-polluted soil, can plant out health, peace
Full property crop high, while, moreover it is possible to soil is carried out excellent modified, reduce pollution, realize the dual of high yield and removing heavy metals
Benefit, has become the emphasis of the research of current planting industry and fertilizer trade.

Chlorophyll content, the photosynthesis of enhancing crop, improve the anti-adversity of crop.
Micro- extract solution, the trace element extracted from simple food materials, rich in zinc, iron and selenium, on the one hand can be work
Thing growth growth is provided needed for trace element, promote the growth of crop, on the other hand, make use of trace element can with it is harmful
There is antagonism in heavy metal, reduce exchangeable species of the heavy metal in soil, suppress the absorption of plant heavy metal, reduce weight
The enrichment of metal, the harm of soil available heavy metal is preferably minimized.
Modified sodium lignosulfonate, is aoxidized after being modified with diatomite by sodium nitrate, is more beneficial for promoting lignin
There is hydrogen bond reaction in sodium sulfonate and heavy metal ion, strengthen its adsorption capacity to available heavy metal.
Modified cyclodextrin, is modified with bentonite to cyclodextrin, make full use of bentonite surface micropore network,
The big porous active material of specific surface area, the cavity of effective increase cyclic dextrin clathrate, reinforced structure unit so that modified
The adsorption capacity of cyclodextrin heavy metal is remarkably reinforced.
Modified alta-mud, the mode that alkalization, salinization and the calcining of specified conditions are combined is carried out to bentonite, by ion
Exchange interaction so that cation exchange out, causes positive charge to lose so that the cation between bentonite bed is changed into solubility
Salt and dissolution, increase interlamellar spacing, formed with the big porous active material of micropore network, specific surface area, increase
Its pore volume, is conducive to the diffusion of adsorption molecule, modified bentonite is had stronger chemism and physical absorption
Property, after calcining, bentonite is heated the impurity that can first lose in surface water, adsorbed water and hole, reduces moisture film and impurity is produced
Raw absorption resistance, is improved its adsorptivity.

Experimental example
In order to further illustrate application value of the invention, inventor have chosen 6 pieces of soy bean test fields of heavy metal pollution,
One of to use common fertilizer as a control group during soybean is planted, another 5 pieces use the embodiment of the present invention 1~5 respectively
Used as experimental group, after testing, 6 pieces of total cadmium content average values on ground are 21.2mg/kg, total chrome content average bits to fertilizer
1152.5mg/kg, lead content average value is carried out during 579.5mg/kg, plantation to 6 pieces of total cadmiums of soil, total chromium, lead contents
Sampling analysis, is counted with reference to soybean yields, as a result as shown in table 1, and 6 blocks of total cadmiums to soybean of product, total chromium, lead is contained
Amount 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 more than 98.5%, conversion ratio of the present invention to soil Cr metal to the conversion ratio of soil cadmium metal
Reach more than 96.8%, the present invention reaches more than 93.3% to the conversion ratio of soil lead metal, a fertilizer of the invention not only huge sum of money
Category repairing effect significantly, also with abundant nutrition, effectively facilitates the growth of crop, and by taking soybean as an example, per mu yield is relative to right
According to group, 8~11.2% can be increased production, realize the double benefit of high yield and repairing heavy metal in soil.
Table 2
Explanation：The soybean of present invention plantation, content of beary metal therein has reached country to soybean content of beary metal
Required standard, total cadmium content≤0.2mg/kg, total chrome content≤1.0mg/kg, the standard of lead content≤0.2mg/kg, it is ensured that
The edible safety of soybean.
