Description
The present invention relates to a kind of agricultural fertilizer, especially a kind of mineral-coated sustaned releasing composite fertilizer and preparation method thereof.
China is large agricultural country, also is that chemical fertilizers production is used big country.Wherein, the amount of application of nitrogenous fertilizer and phosphate fertilizer is first place, the world, but the proportion of composite fertilizer, special-purpose fertilizer is very low.Developed country has realized fertilization compositions based on earth measurement substantially in the world, and the consumption of compound manure and dedicated fertilizer accounts for more than 80%, and the part straight fertilizer is mainly used in and topdresses.And China added up according to 97 years, and multiple (mixing) Hefei turnout only accounts for 15% of fertilizer amount.Because a large amount of applied nitrogens and phosphate fertilizer, other fertile consumption is less, causes the imbalance of soil nutrient structure proportion, soil compaction.Therefore simple substance fertilizer is processed into composite fertilizer, special-purpose fertile, not only uses conveniently, and the synergistic effect between each nutrient can improve its utilization ratio greatly, both economize fertilizer, reduce public hazards again.Result of laboratory test according to the farm crop ash content shows, in its process of growth except that the picked-up a certain amount of moisture, carbonic acid gas and various states nitrogen, the phosphorus potassium silicon magnesium ferrimanganic also is indispensable mineral substance, the oxide aggregate of these 7 kinds of elements has accounted for about 80% of crop ash content unexpectedly, this shows, plant growth not only needs nitrogen phosphorus potassium main nutrient elements, and moderate-element silicon, calcium, magnesium, sulphur can not lack, and trace elements iron, manganese, zinc etc. preferably do not lack yet.At this situation, the personage that agricultural fertile boundary is devoted to study fertilizer has developed various composite fertilizers, and nitrogen phosphorus potassium high-concentration compound fertilizer is arranged, middle lower concentration composite fertilizer is arranged, also there is slow-release compound fertilizer in the composite fertilizer that has immediate effect, and batching is different, performance is also different, but purpose all is one: increase soil nutrient content, coordinate nutrient and form, improve the soil nutrient condition, improve constantly soil fertility, promote agriculture production.People such as contriver Mao Huaiding, the Guo Zhimin of this case just developed a kind of Si, Ca, Mg, K fertilizer (having another name called potash-lime fertilizer, potassic-magnesian fertilizer or Si-K fertilizer) as far back as 78 years, in view of Potash Resources in China limited, the serious situation in short supply of potash fertilizer supply, utilize China's abundant various insoluble potassium bearing rock, Wingdale or dolomite to be main raw material, fire a kind of potassium multi-element-mineral fertilizer that contains that forms through thermal chemical reaction, wherein contain solubility in citric acid K
2O 5～8%, solubility SiO
230～35%, alkali branch (CaO+MgO) 25～30%, also contain trace elements such as a spot of sulphur and ferrimanganic, its principal feature is: not perishable loss, and fertilizer efficiency is significantly lasting, has both alleviated the potash fertilizer supply shortage, amount is fertile plain in replenishing again, and therefore non-secondary pollution, once obtained Henan Province's major scientific and technological achievement prize (seeing Appendix 1).But find that through practical this fertilizer self nutrient is very not comprehensive.Only under the enough prerequisite of nitrogen phosphorus fertilizer, mend and execute this fertilizer and can give full play to just that it is mended potassium, mends silicon, the effect of the magnesium of replenishing the calcium.This makes troubles to peasant household's fertilising, in order to maximize favourable factors and minimize unfavourable ones, abides by the agricultural fertile rule of development, and this case contriver has carried out further exploitation again.
Purpose of the present invention also proposes on this basis at above-mentioned existing in prior technology problem just, is that the potassic mineral manure of principal constituent has the characteristic that is insoluble in water in view of what make with sintering process or scorification with silicon, calcium, magnesium, wrap up easy leaching loss and evaporable nitrogenous fertilizer source and phosphate fertilizer source with it, can prolong fertilizer efficiency, and the change pulvis is granula, becomes single variety into compound kind, modifies fertilizer with fertilizer, make each seed manure have the cooperation of machine, improve utilization ratio separately to greatest extent.
The objective of the invention is to realize by following scheme: this mineral-coated sustaned releasing composite fertilizer is made up of core fertilizer and the integument fertilizer that is wrapped in its outside, wherein: core fertilizer is a high density nitrogenous fertilizer, Wrapped fertilizer is the Si, Ca, Mg, K fertilizer of mineralogical property, the binding agent that also contains fertilizer synergist, little fertilizer additive in the integument and play adhesive effect.
The per-cent (weight ratio) that each composition in the composite fertilizer of the present invention accounts for the fertilizer total amount is:
Nitrogenous fertilizer 20～40%
Si, Ca, Mg, K fertilizer 30～65%
Fertilizer synergist 10～40%
Binding agent 2～6%
Little fertilizer additive 0.2～0.8%
In the present invention, fertilizer synergist can be any one or its combination in Powdered double superhosphate, Powdered Repone K, the vitriolate of tartar.Little fertilizer additive is the water soluble salt of trace element, as: zinc sulfate, copper sulfate etc.
Binding agent can be dilute sulphuric acid or dilute phosphoric acid, and the clay breeze.
The production method of this mineral-coated sustaned releasing composite fertilizer is: at first urea is poured in the pan-pelletizer; the start rotation; spray dilute sulphuric acid and when urea begins to dissolve, add fertilizer synergist and Si, Ca, Mg, K fertilizer; and dilute sulphuric acid fills spray while feeding in raw material; when treating that above-mentioned dose of material all quantitatively adds; add an amount of face powder (toning simultaneously) again; and be rotated further pan-pelletizer; treat after balling-up evenly enwrapped granule fertilizer is transported in the dryer from tablets press and toast that (temperature is controlled at 60 ℃～100 ℃; time was controlled at 0.5～1.0 hour); fertile grain after will drying then cools off, last sorted and packaged.Cooling operation can be taked gas blower blast-cold in cooler, also can take the mode of naturally cooling.
The characteristics of this mineral-coated sustaned releasing composite fertilizer are: (1), contain the required various nutritive elements of plant growth, the constant that had both contained q.s is fertile plain, it is fertile plain to contain the fertile trace plain and a great deal of of relatively large middle amount again, ratio between them can arbitrarily be adjusted as required, for fertilization compositions based on earth measurement is laid a good foundation.Because the synergistic effect between each fertile element is given full play to it and strengthened photosynthetic efficiency, promotes root system development, strong branch bar, enrich seed, opposing disease, comprehensive function such as improve the soil.(2), the existing quick-acting sources of manure, the slow source of manure is arranged again, after handling through parcel, not perishable loss, free from environmental pollution, the storage fertility is made for thing and absorbs for a long time among soil, disposable employed back fertilizer efficiency can be kept several months to 1 year.(3), be partially soluble in water, its aqueous solution is neutral reaction (about pH value 7.0).Suitable all kinds of soil, various crop are made base fertilizer and are used.Amount of application can be decided according to soil fertility, crop varieties.Generally say, every mu of disposable 50～100 kilograms of this fertilizer of executing of ploughing, can manage 1～2 season the crops.(4), do not contain heavy metal and other objectionable impurities, belong to one of best environmental friend fertilizer of public hazards minimum, fertilizer efficiency.At present owing to improper fertilization causes the negative impact of environment has been caused the great attention of relevant department.
