Description
Technical field
The present invention relates to the preparation method of a kind of fertilizer, especially relate to the preparation method of a kind of spacetabs type Chemical Mixed Fertilizer.
Background technology
Fertilizer is to provide nutrient necessary to crop, it is possible to changes soil constitution, increases soil fertility, and increases soil organic substance.Thus the growth promoter that the rational application of fertilizer is to crop, promote crop metabolism, improve crop yield per unit area and play conclusive effect.For avoiding fertilizer nutrient excess supply in soil, coordinate the contradiction between soil nutrient supply and plant nutrient absorption, improve plant recovery of nutrient and reduce harm to environment, exploitation slow release fertilizer be the most efficient and convenient, can fundamentally solve the effective measures of fertilizer loss problem.Slow release fertilizer is changed into plant effective state nutrient rate of release after referring to incorporation of fertilizerin the soil is slower than Quick-dissolving fertilizer.It is slow that slow release fertilizer has nutrients release, and Crop is many, the feature that plant recovery of nutrient is high, uses slow-release fertilizer and can simplify work program, saving of work and time.Current slow release fertilizer both domestic and external is the fertilizer being extended fertilizer efficiency by the physico-chemical process of peplos, parcel, encapsulation, coating, and Quick-dissolving fertilizer and the high molecular polymers such as polyvinyl alcohol, urea aldehyde, sulfur, alkyd based resin, polyurethane based resin are reacted formed parcel or coated fertilizer, these fertilizer not only peplos cost is high, it is difficult to degrade, and environment is had negative effect, thus limit their application.Therefore develop a kind of cost-effective and that preparation method is simple, economic and environment-friendly slow-release bio fertilizer to be very important.
The method the most not overcoming drawbacks described above.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, it is provided that a kind of low cost, production technology are simple, can effectively prevent nitrogen loss, nutrients release slowly, the preparation method of a kind of spacetabs type Chemical Mixed Fertilizer that cycle length, fertilizer efficiency are good.
The present invention is accomplished in that
A kind of preparation method of spacetabs type Chemical Mixed Fertilizer, it is characterized in that: the method comprises the steps: with a kind of liquid preparation as binding agent, decomposed manure, the blended pelletizes such as carbamide, MAP, potassium sulfate form, the mass fraction of its raw material is: decomposed manure 38～48 parts, liquid-containing binder 21～27 parts, carbamide 13～17 parts, MAP 9～13 parts, potassium sulfate 6～8 parts；
The preparation method of described decomposed manure is: according to the mass fraction, by pulverize furfural dregs 40～60 parts, bean cake 20～35 parts, feces of livestock and poultry 15～25 parts, EM microbial inoculum 1～2 parts of mix homogeneously, regulation moisture, to 55%～60%, carries out aerobic fermentation in heap to fermentation tank, turning is started when heap temperature rises to more than 55 DEG C, later every turning in 7 days the most once, turning for the third time 3～after 5 days, material is removed fermentation tank, dry in the sun make moisture to 25%～30%, standby；
The preparation method of described liquid-containing binder adds potassium hydroxide after the furfural dregs fermented and tap water being weighed by the mass ratio of 1:7～1:10, making the mass fraction of potassium hydroxide in solution is 2.5%～3.5%, keep bath temperature at 60～80 DEG C, natural cooling stand 24h after mechanical agitation 2～3h, pour out supernatant, then incorporation accounts for supernatant gross mass 1～the bentonite of 3% or kieselguhr can prepare liquid-containing binder in supernatant；
Described granulation process is by mass fraction, take carbamide 13～17 parts, MAP 9～13 parts, potassium sulfate 6～8 parts of mix homogeneously are stand-by after adding the liquid-containing binder stirring and dissolving of above-mentioned 21～27 parts after pulverizing, take above-mentioned fermentation maturity fertilizer 38 again～48 parts be placed in pelletize in granulating disc, disk rotational add above-mentioned containing carbamide, MAP, the liquid-containing binder of potassium sulfate, after granulating and forming, granule materials is sent into roller drying machine and carries out drying and processing, dry temperature and be 200-250 DEG C, granule materials moisture≤2.5% dried, screening prepares the granular fertilizer of 2～4.75mm；
Described feces of livestock and poultry be chicken, pig, cattle and sheep stool just in any one, any two kinds, any three kinds or the mixture of four kinds.
The present invention has a following effect:
1) low cost, production technology are simple: the spacetabs type Chemical Mixed Fertilizer of the present invention is with a kind of liquid preparation as binding agent, and decomposed manure, the blended pelletize such as carbamide, MAP, potassium sulfate forms.Mass percent is: decomposed manure 38～48 parts, liquid-containing binder 21～27 parts, carbamide 13～17 parts, MAP 9～13 parts, potassium sulfate 6～8 parts.Described decomposed manure is with furfural dregs 40～60 parts, bean cake 20～35 parts, and feces of livestock and poultry 15～25 parts are raw material, adds EM microbial inoculum 1～2 parts, makes through aerobic fermentation.
2) nutrients release is slow, the release phase is long: the fertilizer rate of release of this product is slow, the release phase is long, so that fertilizer nutrient effective rate of utilization is greatly improved.With compared with other fertilizer of concentration, fertilizer efficiency utilization rate can improve 30～50%, makes the consumption of traditional fertilizer greatly reduce, and improvement of environment also can be played positive role.
3) scientific formulation, improve planting benefit and product quality: the present invention is prepared as slow-release fertilizer according to the ratio of science, Nitrogen element nutrien utilization can be made to improve 30～50%, single fertilization just can meet the demand to nutritional labeling in crop time of infertility, compared with common fertilizer, amount of increase in production reaches 6～10%, has and uses low cost, to features such as Soil Environmental Pollution are little.The rate of fertilizer of 35～55% can be reduced in the case of the identical yield of crop.The crop single-dose application of one season, saving of work and time, economic benefit is obvious.
4) achieve refuse reclamation, add the economic value added of furfural dregs: furfural dregs is as the garbage produced during biomass by hydrolyzation, and its salt content is high, in acidity, and air, soil, river can be produced and pollute by bulk deposition.Containing substantial amounts of cellulose, hemicellulose, lignin in furfural dregs, there is good recycle value.Reasonably recycling furfural dregs is developed in the success of this product, eliminate its pollution to environment, add the economic value added of furfural dregs, it is achieved that the zero release of pollutant target in furfural enterprise production process simultaneously, reach cleaning production, the purpose of the cyclic utilization of waste.
