Description
Technical field
The invention belongs to technical field of fertilizers, be specifically related to a kind of organic functions containing PAL biological restoration preparation fertilizer
Preparation method.
Background technology
1, China's chemical fertilizer use situation
China is a populous country, mainly uses the labor type of nature agro-farming.Wherein, grain
Produce in the development of agricultural production, occupy important position.Fertilising can not only be increase soil fertility, and is to improve crop
The important measures of yield per unit area.Chemical fertilizer be agricultural production the most basic and also be most important material put into.According to the United Nations's grain
Agriculture tissue (FAO) is added up, and chemical fertilizer accounts for 40%～60% in the total share to increasing crop yield.China can be to account for the world 7%
Arable land support the population in the Liao Zhan world 22%, it may be said that chemical fertilizer plays very important effect.Meanwhile, according to decomposition result also
" Agricultural Sustainable Development in China DSS " (CHINAGRO) is utilized to predict the year two thousand twenty whole nation and each province's fertilizer application
Amount situation.Modal analysis results shows if taken no action to, the use total amount of China's chemical fertilizer in future and unit sown area
Fertile amount of application will still present growth trend, and unit are fertilizer amount will be higher than the international upper limit mark of 225kg/hm2 for a long time
Accurate.
2, agricultural material uses aggravation heavy metal pollution of soil
The unreasonable of agricultural material such as pesticide, chemical fertilizer, mulch film, feces of livestock and poultry and sludge composting product are used, and may result in agriculture
Field heavy metal pollution.Containing Hg, As, Cu, Zn etc. in some pesticide.At present, the pesticide containing As, Hg and Pb is at most countries
Disabling (such as China, the U.S., Japan and European Countries etc.), but the various antibacterial containing Cu and Zn are (such as Bordeaux mixture, many peaceful, alkali
Formula copper chloride, ziram, zinc thiazole, zineb etc.) also it is widely used in the agricultural production of countries in the world, enter with pesticide every year
Cu and Zn in farmland can not be ignored, China about 5000t and 1200t.Heavy metal is to report most polluters in fertilizer, its matter
Amount mark is usually phosphate fertilizer > compound fertilizer > potash fertilizer > nitrogenous fertilizer.In France farmland, Se, Cr and Cd are essentially from mineral fertilizer, wherein phosphorus
In fertilizer, Cr and Cd mass fraction is the highest.In ammonium nitrate, ammonium phosphate, compound fertilizer, As is up to 50-60mg kg-1, agricultural mulching produces
During add containing Cd and Pb heat stabilizer, also can increase the risk that farmland soil heavy metals is polluted during use.Animal dung
Just and composting production chronic administration is the most increasingly severe to the pollution of heavy metals in farmland.During livestock and poultry cultivation, except making
With the feed additive containing Cu and Zn, the most also with the additive containing As, Cd, Cr, Pb and Hg, and heavy metal matter in feces of livestock and poultry
Amount mark is directly related with feedstuff.The farmland soil heavy metals pollution level of chronic administration feces of livestock and poultry increases the weight of.It addition, city is dirty
In mud, Cr, Pb, Cu, Zn and As easily exceed control standard, use and farmland soil heavy metals mass fraction can be made to have in various degree
Increase.
3, PAL material and Patents
The raw material of PAL material is Paligorskite (also known as attapulgite), for a kind of crystalloid hydrous magnesium aluminium silicate mineral, has
, there is crystal lattice in unique layer chain structure feature in its structure, containing variable amount of Na in crystal+、Ca2+、Fe3+、Al3 +, crystal is needle-like, threadiness or fiber collection shape.The biotechnologies such as purified, ultramicronising, activation, modification and ecological agriculture
The nonmetal ecomaterial of natural inorganic that industry processing technique manufactures.Can non-traditional ore deposit as denitrogenating, outside phosphorus, potassium conventional fertilizers
Thing fertilizer.PAL material can provide outside grand nutrition element potassium, phosphorus, can provide 12 kinds with iodine, selenium, zinc, ferrum as representative galore
Soil micronutrient element.The mineralogical characteristic of PAL material and structural texture, be again admittedly to deposit nutrient and field that microorganism is bred
Territory.
Additionally, PAL material is used for improveing soil, in addition to having stronger fertilizer conservation, water retention property, it can also increase soil
The buffer capacity of earth, the harmful element (lead, arsenic, hydrargyrum, chromium etc.) in absorption soil, effectively remove heavy metal in soil and pollute.By
Construction features in clay mineral itself, it is possible to use fixation principle fixes a part of heavy metal element in soil, thus drops
The absorbtivity of low plant heavy metal element.The external condition of attapulgite (Paligorskite) mineral formation be PH be about 8 high-alkali
Proportional suitable SiO in degree, suitable salinity, uniform temperature and medium2、Al2O3With MgO component, have abundant in its structure
Passage adsorbent soil in heavy metal ion, reach the fixing purpose of part.Utilize adsorption function and the slow release merit of PAL material
Can, " farm chemical residual eliminator " can be made, it then follows " Subtraction method " principle, reduce pesticide residues, produce pollution-less agriculture product.
Have with the patent that Paligorskite prepares fertilizer for raw material, a kind of Attapulgite mineral powder slow-release fertilizer (10170702.X), one
Plant rare earth attapulgite complex mineral fertilizer (10049829.0), a kind of novel reinforced nutrient green " LB " fertilizers
(10669361.0), it is prepared from mainly by attapulgite clay mixing many clocks trace element.The trace that extra mixing increases
Element can bring the increase of cost, and can bring for some specific contaminated lands and pollute the minus effect increased the weight of.
