Description
Technical field
The invention belongs to fertilizer field, more particularly to a kind of compound trace element fertilizer and preparation method thereof.
Background technology
Current domestic soil is contaminated serious, causes the grain heavy metals exceeding standard of plantation, and soil is contaminated grain heavy metals exceeding standard
Reason is as follows：
1. the heavy metal-containing waste water of contaminating enterprises flows directly into cultivated soil, then it is absorbed by plants；
2. waste gas and vehicle exhaust of contaminating enterprises etc. contain SO2Gas be directly discharged in air, pollute air after, shape
Into acid rain, make soil acidification, allow the inactive heavy metal ion of script to become lively, be absorbed into fruit；
3. long-term unreasonable fertilising is the primary killers for causing environmental pollution and Food Security.Because soil is only applied big for a long time
Secondary element N P and K, secondary and micro-element fertilizers are supplemented without applying, make the serious of the active metal ions such as Trace Elements in Soil
Missing, is a critically important reason for causing grain heavy metals exceeding standard.
With the progress that the eighties are reformed and opened up to the outside world, Chinese agriculture also abandoned traditional use pig, dog, people in 83 years almost all
Tillage method of the fermentations such as excrement, green grass as fertilizer, change using nitrogen, phosphorus, potassium three kinds of chemical fertilizer kinds, these three chemical fertilizer are altogether
Contain N, P, K, C, H, O, S etc. and be no more than 8 kinds of elements, and kind is big about more than 30 for the vital movement of plant needs
Middle micro- participation, the active Cu of the comparisons of particularly two valencys2+、Fe2+、Mn2+、Zn2+, B2+Compare active Cu2+、
Fe2+、Mn2+、Zn2+、Mg2+、Ca2+Deng the ion exchange of the participation root system of element ion.Existing shape only applies N, P, K tri-
The tillage method of kind fertilizer has continued more than 30 years, so as to cause middle micro- serious loss in soil, while also causes
Plant original torpescence is difficult to be absorbed with eating what there is when being hungry heavy metal cation lead after acidified be activated, cadmium, chromium etc. from
Son is absorbed, so as to cause grain heavy metals exceeding standard.Excessive nitrogenous fertilizer in soil, causes the generation of nitrite and nitrate,
So that its content overproof, and nitrite and nitrate can form thing for cancer with amine or acid amides.And heavy metal and a large amount of poisonous and harmful
The generation of material can all cause seriously to pollute to soil.
In a word, Food Security is due to social development, and process of industrialization is accelerated, and causes water, vapour to soil pollution,
Soil acid-base disequilibrium and modern agriculture is caused to substitute the long-term unreasonable fertilising of traditional agriculture to cause big necessary to plant in soil
In micro- nutrient ratio balance so that heavy metal lead cadmium plasma activation is by the serious problems caused by a large amount of absorb.
And wheel of history always rolls forward, process of industrialization is accelerated and modern agriculture substitution traditional agriculture is inevitably develop
Trend.
The resolution of grain heavy metals exceeding standard is mainly at present：Contaminated soil is pulled away, immigration there is not contaminated soil；It is this
Method, can effect a permanent cure in the short term, but after 20,30 several years soil still can by water, contaminated vapor, therefore
Still need to dial after several years from soil, assembled moreover, the contaminated soil pulled away also needs to a large amount of places, actual is also to control
A kind of not this processing method, and it is costly, and engineering difficulty is very big.
The content of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of fertilizer efficiency is permanent, nutrient is comprehensive, nuisanceless, free of contamination
Compound trace element fertilizer and preparation method thereof, the compound trace element fertilizer can not only improve grain nutritive value and yield, also have can permanent repair and
Administer the function of the repairing and treating of contaminated soil.
To achieve these goals, the invention provides a kind of compound trace element fertilizer, it is characterised in that required raw material and its weight percent
It is respectively than content：The high soil conditioner sepiolite powder 14 of basic soil pH value conditioner lime 30%-60%, silicon content
- 28%, powdered carbon 2-4%, diatomite in powder 11%-22%, soil heavy metal passivant 3-6%, micro and moderate-element salt
10%.
Present invention also offers a kind of compound trace element fertilizer preparation method, it is characterised in that comprises the following steps：
(1) production is granulated using granulating disc, and is first sufficiently mixed lime and sepiolite powder, powdered carbon, diatomite in powder,
Then put into granulating disc and be granulated；
(2) saturation urea liquid is used as binding agent slurry-spraying pelletizing, when its granularity reaches 80-85% in 2-4 millimeters section
When add the pure sepiolite powder of people to be wrapped in the top layer of its hybrid particles in right amount；Placing when more than 90% 2-4 millimeters are reached in granulation disc,
Conditioning absorbent particles are made；
(3) micro and moderate-element salt is sufficiently mixed another individually granulation, its specification and reaches more than 90% 2-4 millimeters, be made multiple
Close micro- fertile particle；
(4) two kinds of particles to be sieved respectively, its product specification all takes 2-4 mm granules, then by two kinds of particles by weight 9: 1
It is sufficiently mixed into compound trace element fertilizer；
(5) finished product packing bag is loaded after drying.
The beneficial effects of the invention are as follows：
(1) acidified soil is neutralized, is carried added with the basic soil pH value conditioner lime for neutralizing acid soil in compound trace element fertilizer
High P in soil H values, reduce the activated state content of heavy metal lead cadmium ion；So as to which heavy metal be greatly reduced in cereal product
Content and enrichment.
(2) the high soil conditioner sepiolite powder of silicon content of the addition with strong absorption heavy metal ion function, charcoal in compound trace element fertilizer
Powder and diatomite in powder, strengthen the permeability of soil and effectively improve P in soil H values, make the heavy metal lead cadmium plasma that is activated extensive
Multiple inertia reduces mobility, is passivated absorption in soil, it is difficult to by cereal crops Absorption and running to root system and fruit；So as to
Content and enrichment of the heavy metal in cereal product is greatly reduced.
(3) a variety of active metal cation such as Cu are contained in compound trace element fertilizer2+Fe2+Mn2+Zn2+Si2+B2+Mg2+Ca2+Etc. micro and
Moderate-element so that soil largely reduced in cation percent occupancy volume contained by heavy metal cation lead, cadmium etc.
Shared ratio, reduce by absorbing probability, reaching makes heavy metal lead cadmium plasma quantitatively few effect absorbed by cereal crops；
So as to which content and enrichment of the heavy metal in cereal product be greatly reduced.
(4) it is the trace element that serious loss must be supplemented with modern agriculture soil to apply trace element in the present invention, and every mu is applied
With 100 kilograms, it can reach and increase yield 15%-50%, improve nutritive value, increase the good result of economic benefit.
