Description
Technical field
The present invention relates to a kind of preparation method of fertilizer, especially relate to a kind of preparation method of slow release type Chemical Mixed Fertilizer.
Background technology
Fertilizer is to provide the necessary nutritive element of crop, can change soil constitution, increases soil fertility, and increases soil organic substance.Thereby the rational application of fertilizer is to the growing of crop, and promotes crop metabolism, improves crop yield per unit and play conclusive effect.For avoiding fertilizer nutrient excessive supply in soil, coordinate the contradiction between soil nutrient supply and plant nutrient absorption, improve plant recovery of nutrient and reduce the harm to environment, exploitation slow release fertilizer is effective measure the most efficient and convenient, that can fundamentally solve fertilizer loss problem.Slow release fertilizer refers to that to change the rate of release of plant effective state nutrient after incorporation of fertilizerin the soil into slower than Quick-dissolving fertilizer.Slow release fertilizer has nutrient and discharges slowly, and Crop is many, and the feature that plant recovery of nutrient is high is used slow-release fertilizer and can be simplified work program, saving of work and time.Current slow release fertilizer both domestic and external is the fertilizer that extends fertilizer efficiency by the physico-chemical process of coating, parcel, packing, coating, and Quick-dissolving fertilizer is reacted to formed parcel or coated fertilizer with high molecular polymers such as polyvinyl alcohol, urea aldehyde, sulphur, alkyd based resin, polyurethanes resins, not only coating cost is high for these fertilizer, hard degradation, and environment is had to negative effect, thereby limit their application.Therefore develop a kind of cost-saving and preparation method is simple, the slow-release bio fertilizer of economic environmental protection is very important.
Also do not overcome so far the method for above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, the preparation method that a kind of low cost, production technique are simple, can effectively prevent a kind of slow release type Chemical Mixed Fertilizer that nitrogen loss, nutrient discharge slowly, the cycle is long, fertilizer efficiency is good is provided.
The present invention realizes in the following way:
A kind of preparation method of slow release type Chemical Mixed Fertilizer, it is characterized in that: the method comprises the steps: take a kind of liquid preparation as binding agent, decomposed manure, the blend granulations such as urea, monoammonium phosphate, potassium sulfate form, the mass fraction of its raw material is: 38～48 parts of decomposed manures, 21～27 parts of liquid-containing binders, 13～17 parts, urea, 9～13 parts of monoammonium phosphates, 6～8 parts of potassium sulfate;
The preparation method of described decomposed manure is: according to the mass fraction, and by 40～60 parts of the furfural dregs of pulverizing, 20～35 parts of dregs of beans, 15～25 parts of feces of livestock and poultry, 1～2 part of EM microbial inoculum mixes, and regulates moisture to 55%～60%, piles to fermenter and carries out aerobic fermentation, in the time that rising to more than 55 ℃, heap temperature starts turning, every turning in 7 days once, turning for the third time, after 3～5 days, is shifted out fermenter by material later, airing makes moisture content to 25%～30%, for subsequent use;
The preparation method of described liquid-containing binder adds potassium hydroxide after the furfural dregs having fermented and tap water are weighed by the mass ratio of 1:7～1:10, the massfraction that makes potassium hydroxide in solution is 2.5%～3.5%, keep bath temperature at 60～80 ℃, naturally cooling standing 24h after mechanical stirring 2～3h, pour out supernatant liquor, then to mix in supernatant liquor account for the wilkinite of supernatant liquor total mass 1～3% or diatomite can obtaining liq binding agent;
Described granulation process is for pressing mass fraction, get 13～17 parts, urea, 9～13 parts of monoammonium phosphates, 6～8 parts of potassium sulfate mix after the liquid-containing binder stirring and dissolving that adds above-mentioned 21～27 parts after pulverizing stand-by, get again 38～48 parts of above-mentioned fermentation maturity fertilizers and be placed in granulating disc granulation, disk adds the above-mentioned urea that contains in rotating, monoammonium phosphate, the liquid-containing binder of potassium sulfate, after granulating and forming, granule materials is sent into roller drying machine and carry out drying and processing, bake out temperature is 200-250 ℃, granule materials moisture≤2.5% of drying, screening makes the granular fertilizer of 2～4.75mm,
Described feces of livestock and poultry be in chicken, pig, ox and sheep ight soil any one, any two kinds, the mixture of any three kinds or four kinds.
The present invention has following effect:
1) low cost, production technique are simple: slow release type Chemical Mixed Fertilizer of the present invention is take a kind of liquid preparation as binding agent, and decomposed manure, the blend granulations such as urea, monoammonium phosphate, potassium sulfate form.Mass percent is: 38～48 parts of decomposed manures, 21～27 parts of liquid-containing binders, 13～17 parts, urea, 9～13 parts of monoammonium phosphates, 6～8 parts of potassium sulfate.Described decomposed manure is with 40～60 parts of furfural dregs, 20～35 parts of dregs of beans, and 15～25 parts of feces of livestock and poultry are raw material, add 1～2 part of EM microbial inoculum, make through aerobic fermentation.
2) nutrient discharge slow, release period is long: the fertilizer rate of release of this product is slow, release period is long, thereby fertilizer nutrient effective rate of utilization is greatly improved.Compared with other fertilizer of same concentration, fertilizer efficiency utilization ratio can improve 30～50%, and the consumption of traditional fertilizer is greatly reduced, and also can play active effect to environmental improvement.
3) scientific formulation, improve planting benefit and quality product: the present invention is prepared into slow-release fertilizer according to the ratio of science, can make Nitrogen element nutrien utilization improve 30～50%, single fertilization just can meet the demand to nutritive ingredient in crop time of infertility, compared with common fertilizer, amount of increase in production reaches 6～10%, has the cost of using low, to features such as Soil Environmental Pollution are little.The in the situation that of the identical output of crop, can reduce by 35～55% rate of fertilizer.The crop single-dose application of one season, saving of work and time, economic benefit is obvious.
4) realized refuse reclamation, increased the economic value added of furfural dregs: furfural dregs is as the waste producing in biomass by hydrolyzation process, its salt content is high, be acid, and bulk deposition can produce and pollute atmosphere, soil, river.In furfural dregs, contain a large amount of Mierocrystalline celluloses, hemicellulose, xylogen, there is good recycle value.Recycling has been developed reasonably in the success of this product furfural dregs, eliminate its pollution to environment, increase the economic value added of furfural dregs simultaneously, realized the zero release of pollutant target in furfural enterprise production process, reached the object of cleaner production, the cyclic utilization of waste.
