Description
Technical field
The present invention relates to a kind of water-saving medicine slag film coating base fertilizer and production method thereof, belong to agrochemical field.
Background technology
China is one of 13 poor-water countries in the world, and agricultural water accounts for about 75% of total water consumption.Innovation agricultural fertilizer mode, the development new-type fertilizer is saved irrigation water, is the effective way that realizes agricultural water conservation.But traditional agriculture production at present also will impose chemical fertilizer 2 ~ 3 times in crop growth period except that applying fertilizer to the subsoil, generally will cooperate after topdressing and water, and has increased water total amount, every 1m
3Aquatic product grain is only about 1kg, far below the benefit of pouring water more than the 2.6kg of developed country.
The research and the corresponding techniques that change fertilizer, water saving are many, and total summary gets up to have: kind of method surplus engineering water saving, agronomy water saving, chemistry water saving, the fertilizer water saving etc. five.Its engineering water saving has anti seepage channel, pipe filling, drip irrigation, slight irrigation, membrane covering etc., and these amounts of investment are big, the engineering complexity; The agronomy water saving mainly is intensive cultivation, and current large quantities of labor forces go down town and work, the value of labour power multiplication, and the measure of agronomy water saving is incompatible with the labor capacity that needs to drop into, and stay-at-home labor force also is difficult to accept; Biological water saving is subjected to the restriction of industry such as breeding, is difficult to accomplish that every kind of crop can both lean on species to realize water saving; The chemistry water saving is the water absorption character realization water saving by the chemosynthesis material, and the macromolecular material of these chemosynthesis pollutes environment easily, is difficult to realize water saving, environmental protection doulbe-sides' victory; The fertilizer water saving mainly is to be in the development slow-release or control-release fertilizer in demonstration popularization stage, and present this fertilizer costs an arm and a leg, and is used for general large farm crop and is difficult to realize the low high production that drops into, and the peasant temporarily is difficult to accept.
China bio-pharmaceuticals factory is more, and mostly the present stage residue application of fermented liquid is that as feed wherein remaining microbiotic accumulates or cause the resistance of biology easily by biologic chain.Be sticky shape during these dregs of a decoction water content 50% left and right sides, contain the amino acid about 20%, about 15% protein, about 40% organic matter, as long as scientific compatibility is selected proper production process for use, it is feasible fully to use medicine slag film coating production compound fertilizer.
Summary of the invention
Based on above-mentioned background, the present invention has overcome the deficiency of above-mentioned water saving measures, and a kind of water-saving medicine slag film coating base fertilizer and production method thereof that can the slowly-releasing fertilizer efficiency be provided.
The present invention is achieved by the following technical solutions:
A kind of water-saving medicine slag film coating base fertilizer, its special character is: makes by composite fertilizer and liniment,
Described composite fertilizer is made by following raw material: nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, middle trace element fertilizer, ammonification humic acid powder;
Described composite fertilizer is made by following raw material: the fermented liquid, xylogen powder, tackiness agent, talcum powder, the stablizer that are used to produce the cephalosporin medicament.
Water-saving medicine slag film coating base fertilizer of the present invention, liniment account for the 3-4% of gross weight.The described fermented liquid that is used to produce the cephalosporin medicament is moisture 50% cephalo fermentation residue, and cephalo fermentation residue, xylogen powder, tackiness agent, talcum powder, stablizer were by 88: 5: 2: 3: 2 part by weight cooperates.
This kind water-saving medicine slag film coating base fertilizer production craft step is as follows:
(1) production of granular complex fertilizer:
Earlier nitrogenous fertilizer (containing N 15-25%), phosphate fertilizer (are contained P
2O
56-15%), potash fertilizer (contains K
2O 9-10%), middle trace element fertilizer pulverizes, and by producing required suitable proportion, adds ammonification humic acid powder then, in granulating disc, with 20 rev/mins rotating speed granulation, drying is made granular complex fertilizer, and is stand-by;
(2) production of liniment:
Employing is used to produce the fermented liquid of cephalosporin medicament, steam heating is condensed into moisture 50% cephalo fermentation residue, then with moisture 50% cephalo fermentation residue, xylogen powder, tackiness agent, talcum powder, stablizer in 88: 5: 2: after 3: 2 ratio cooperates, stirred 10 ~ 20 minutes with 15 rev/mins speed, water vapor is heated to 60 ℃ and becomes stable sticky shape fluid liniment.
(3) production of medicine slag film coating base fertilizer:
Liniment with step (2) gained passes through jet apparatus, the granular complex fertilizer hydrojet of making in the step (1) is filmed, the back particle of filming is sent into dryer through travelling belt, is dried into product under the 60-70 ℃ of condition, and weighing pack warehouse-in can be produced water-saving medicine slag film coating base fertilizer; When wherein filming, liniment consumption: 3%-4%, composite fertilizer's consumption: 96%-97%, in the bottom application fertilizer product of producing, liniment accounts for the 3-4% of gross weight.
Adopt technology of the present invention to produce the throughput 〉=10t/h of water-saving medicine slag film coating base fertilizer.
Medicine slag film coating fertilizer has the function of slowly-releasing fertilizer efficiency, and the bottom application disposable fertilizer can satisfy the needs of crop whole growth phase, and the fertilizer bottom application of filming can reduce the number of times or do not water of watering that topdresses, and can realize preferably saving and pour water.
Mainly be the used liniment prescription and the production technique of liniment with innovation part of the present invention.The present invention makes full use of nutritive ingredients such as amino acid in the residue of fermented liquid, protein, organic matter, and through repetition test, raw materials used compatibility science, production technique are appropriately reasonable.The base fertilizer that adopts the technology of the present invention to produce can be controlled the fat effect release rate of conventional compound.This fertilizer of filming is used as bottom application, can satisfy the needs of crop whole growth phase, reduces the number of times that waters that topdresses in the crop growth period, realizes water saving; The cephalo fermentation residue that is coated with in the rete can effectively suppress the infringement of crop soil-borne disease bacterium, strengthens crop disease-resistant.The present invention had both solved the pollution of the dregs of a decoction after discarded, had innovated utilizing mode and alleviating the agricultural water shortage problem of the dregs of a decoction; meet the requirement of environment protection, medical fermentation industry recycling economy and agricultural sustainable development again; and it is simple to operate; easily realize industrialization, economic, society, ecological benefits are obvious.
