Description
Technical field
The invention belongs to agricultural fertilizer technical fields, and in particular to a kind of multi-functional organic-inorganic medicine fertilizer and its preparation side
Method.
Background technology
Oil tea is the distinctive woody oleiferous plants crop in China, and it is about 4,000,000 hectares that, which there is camellia oleifera lam in the current whole nation, is mainly distributed on
South China province.Extracted From Oil-tea-cake is oil tea remaining residue after oil expression, contains protein, grease, Tea Saponin, crude fibre, sugar
The substances such as class, tannin, caffeine.China's Extracted From Oil-tea-cake yield is very high, due to Extracted From Oil-tea-cake bitter, and also it is toxic, it is impossible to directly as
So major part grouts are burned off or abandon as fuel at present, Fertilizer application is used as after part fermentation for feed.Tea Saponin
Biocidal efficacies are one of the major advantage of Extracted From Oil-tea-cake as fertilizer.However, Extracted From Oil-tea-cake in acid soil in the south environment in use, by
Low in Tea Saponin dissolution rate, Tea Saponin concentration is not high in the micro- domain environment of soil, and bactericidal effect is limited.
Excessively application is serious for China's chemical fertilizer and pesticide, thus causes such as environmental pollution, soil acidification, agricultural product peace
Congruent series of problems.The main reason for chemical fertilizer and pesticide are excessively applied falls relatively including the research and development of the substitute products of chemical fertilizer and pesticide
Afterwards, fertilising, dispenser equipment independent research and development capacity are weak, and fertilizer loss is big, and pesticide evaporating, emitting, dripping or leaking of liquid or gas is serious etc..Solving the problems, such as these is
Key technology includes chemical fertilizer/pesticide reduction synergy, organic fertilizer replacing fertilizer, soil quality lift technique etc..Wherein, new fertilizer
Material, the research and development of pesticide are the key that China realizes that chemical fertilizer and pesticide subtract and applies synergy.
The content of the invention
The present invention provides a kind of multi-functional organic-inorganic medicine fertilizer and preparation method thereof, by urea first made from urea and formaldehyde
Aldehyde and Extracted From Oil-tea-cake, calcium and magnesium phosphorus, potassium chloride, concave convex rod and the multi-functional organic-inorganic medicine fertilizer finished product of kaolin mixing system.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of multi-functional organic-inorganic medicine fertilizer, raw material include by weight percentage：
Extracted From Oil-tea-cake 30~40%；
Urea 5~10%；
Formaldehyde 5~10%；
Calcium and magnesium phosphorus 15~25%；
Potassium chloride 10~20%；
Concave convex rod 5~15%；
Kaolin 5~15%.
The preparation method of multi-functional organic-inorganic medicine fertilizer is：40 DEG C are warming up to after the mass mixings such as urea and water, dissolving, is used
Sodium hydroxide solution is adjusted to pH 7.0~7.5；When 40% formalin of addition volume fraction reaction 1.5 is small, phosphoric acid solution is used
Adjust to pH 3.0~3.5, and 40 DEG C reaction 1.5 it is small when after filter；Mixture is taken out, adds in and is filled by the Extracted From Oil-tea-cake crushed
Divide stirring, add other raw materials by crushing, be mixed evenly, be granulated, drying, cooling down, sub-sieve, be made granular
Multi-functional organic-inorganic medicine fertilizer finished product.
The fineness of the Extracted From Oil-tea-cake is the mesh of 20 mesh ~ 40, calcium and magnesium phosphorus, potassium chloride, the fineness of concave convex rod and kaolin concave convex rod
In the mesh of 20 mesh ~ 60, the calcium and magnesium phosphorus P2O5Content more than 16%, the particle diameter of the multi-functional organic-inorganic medicine fertilizer of gained is 3 ~ 5
mm。
The ureaformaldehyde as made from urea and formaldehyde of the multi-functional organic-inorganic medicine fertilizer addition of the present invention is except can conduct
Outside source of slow release nitrogen, also there is higher pH value, acid soil acidity can be adjusted.On the one hand Extracted From Oil-tea-cake can improve soil carbon and contain
Amount, another aspect Extracted From Oil-tea-cake have higher Tea Saponin, have biocidal efficacies, and can adsorb heavy metal in soil effect.This
It is since the alkaline environment of ureaformaldehyde and the offer of calcium and magnesium phosphorus promotes Extracted From Oil-tea-cake to release a large amount of Tea Saponins in a short time, further
Extracted From Oil-tea-cake bactericidal effect is improved, overcomes existing chemical fertilizer and the pesticide soil degradation that largely application is brought（Acidifying）, environmental pollution,
The problems such as agricultural product security.Further, since oil tea saponin carries hydrophilic lipophilic group ligand, there is amphipathic, hydrophilic radical
It is the oxygen-containing group by strong electronegativity（-O-、-OH、-COO-、-COOH）Composition, these groups are mainly by the saponin(e of oil tea saponin
The connecting portion of aglucon, saccharide ligand and organic acid ligand is formed；Lipophilic group is made of sapogenin, is by nonpolar
Hydrocarbon loop chain is formed, and hydrophobic tendency is presented in aqueous solution, becomes oleophylic main body.In the alkalescence that ureaformaldehyde and calcium and magnesium phosphorus provide
The amphipathic oil Tea Saponin dissolved out in environment is in anionic, and effect is similar to anionic surfactant, the work(formed
The heavy metal ion that can largely adsorb in soil can be rolled into a ball.Therefore, multi-functional organic-inorganic medicine fertilizer provided by the invention, which has, adjusts
Section soil aciditiy adsorbs heavy metal ion, improves soil texture, slows down fertilizer nutrient rate of release and other effects.
The remarkable advantage of the present invention is：
(1) multi-functional organic-inorganic medicine of the invention fertilizer simultaneously there is offer nutrient (organic matter, nitrogen, phosphorus, potassium etc.), nutrient to have
The effect phase is long, adjusts the functions such as acid soil acidity, sterilization.
(2) multi-functional organic-inorganic medicine fertilizer bactericidal effect of the invention is significantly higher than Extracted From Oil-tea-cake and is administered alone.Extracted From Oil-tea-cake exists
The alkaline environment that ureaformaldehyde and calcium and magnesium phosphorus provide can promote Extracted From Oil-tea-cake to discharge a large amount of Tea Saponins, the micro- domain ring of soil in a short time
Tea Saponin concentration in border is significantly higher than Extracted From Oil-tea-cake and processing is administered alone, and adsorbs heavy metal ion, improves soil pollution.
(3) simple production process of multi-functional organic-inorganic medicine fertilizer of the invention, processing cost is relatively low, using facilitating, easily
In large scale application.
