Description
Technical field
The present invention relates to the means of agricultural production field of agricultural production, especially a kind of Fertilizer rod and processing method thereof.
Background technology
The method that the many employings of Crops in Applying Fertilizer in China rural area are shed at present, and sprinkling fertilization is uneven, and scatter on ground, fertilizer loss is relatively big, less effective.Crop row spacing more greatly and do not seal capable crops topdress can ditch spread, once crops envelope row just cannot ditch spread.Although having many compound fertilizers to have certain slow release effect on market, but single-dose application being still not enough to ensure the fertilizer needs of the full trophophase of crop at seeding time.
Polyvinyl alcohol is a kind of white plates, cotton-shaped or pulverulent solids, tasteless.Refractive index 1. 49～1. 52, thermal conductivity 0.2w/ (m K), specific heat capacity 1～5J/ (kg K), resistivity (3.1～3. 8) × 10 Ω cm.It is dissolved in water, typically need to be heated to 65～75 DEG C to be completely dissolved.Material should first under agitation be added in room temperature water by polyethylene dissolving alcohol, heats up again and accelerates to dissolve, be so possible to prevent caking, affect dissolution velocity after being uniformly dispersed.Polyvinyl alcohol water solution (5%) is very sensitive to Borax, boric acid, easily causes gelation, when Borax reaches the 1% of solution quality, will produce irreversible gelation.Chromate, bichromate, permanganate also can make polyvinyl alcohol gel.Polyvinyl alcohol water solution viscosity the most in time is gradually increased. but concentration is viscosity when 8% is absolute stable, unrelated with the time, a phenomenon c polyvinyl alcohol good film-forming property, the many gases in addition to steam and ammonia are had the uncomfortable gas of height.Light resistance is good, not by illumination effect.Nontoxic, to human body skin nonirritant.Polyvinyl alcohol is uniquely can be by antibacterial as carbon source and the polyvinyl of utilization of energy, under the effect of antibacterial and enzyme, and 46 days degradables 75%, belong to a kind of Biodegradable polymer material, can be cheap by Non oil-based route large-scale production.Polyvinyl alcohol is nonpoisonous and tasteless, pollution-free, can dissolve in 80--90 DEG C of water.Its aqueous solution has good cementability and film property；There is the chemical property such as long-chain polyhydric alcohol esterification, etherificate, acetalation.Polyvinyl alcohol is agriculturally currently used primarily in soil conditioner, pesticide adheres to synergist and polyvinyl alcohol film.Water-soluble polyvinyl alcohol film is a kind of novel plastic product shown up prominently in the world, and it make use of the film property of polyvinyl alcohol, water and biological two kinds of degradation characteristics, can be degradable for CO2 with H2O, the high-new environment-friendly package material of green being worthy of the name.American-European, Japanese, water-solubility PVA film is widely used in the packaging of various product.
Zinc stearate can be used as heat stabilizer；Lubricant；Grease；Accelerator；Thickening agent etc..Such as may generally serve as polyvinyl alcohol resin heat stabilizer.Zinc stearate lubricity is good, can improve fouling precipitation phenomenon, is alternatively arranged as lubricant, releasing agent, and the flatting agent of paint, and zinc stearate runs into acid and resolves into stearic acid and corresponding salt；There is hygroscopicity.
Summary of the invention
The technical problem more difficult for solving the fertilising of crop growth phase, the present invention provides a kind of Fertilizer rod and preparation method thereof, required for farming growth fertilizer is fabricated to Fertilizer rod, in being once manured into soil when sowing or topdressing, by the film that can slow down dissolving in Fertilizer rod and the internal less soluble synthetic resin added, extend fertilizer efficiency period so that the whole trophophase of crops can be continuously available fertilizer supply, reduce human cost, improve planting benefit.
The present invention is achieved in that
A kind of Fertilizer rod, including NPK compound fertilizer, polyvinyl alcohol, zinc stearate and glycerol, it is characterised in that the formulation weight ratio of described Fertilizer rod is: NPK compound fertilizer 80-90, polyvinyl alcohol 8-15, zinc stearate 0.5-1 and glycerol 1-5；Described Fertilizer rod be cross-sectional area be 0.5-2.0 square centimeter, the cylindricality of long 1.0-3.0 centimetre.Preferably formulation weight ratio is: NPK compound fertilizer 88, polyvinyl alcohol 10, zinc stearate 0.5 and glycerol 1.5.In formula, with NPK compound fertilizer for Fertilizer rod main body, with zinc stearate as stabilizer, polyvinyl alcohol for partial gelation agent, glycerol as plasticizer, the Fertilizer rod made is difficult to loose, and slow release effect is preferable.
The Fertilizer rod of the present invention, described NPK compound fertilizer can be the compound fertilizer that N, P, K content respectively accounts for 15%；Can also is that weight proportion includes carbamide 15-20, fusing phosphate fertilizer 15-25 and the compound fertilizer of potassium dihydrogen phosphate 35-55；It can also be the formula needing to contain fertile measurement with soil according to crop growth and formulating.Use different compound fertilizer's formula according to Different Crop with different soils fertilizer feelings, be more beneficial for the growth promoter of crops, main product stable yields.
For distinguishing the different fertilizer rod kind that Different Crop uses, the shape of cross section of the Fertilizer rod of the present invention can be circular, triangle or polygon, it is also possible to adds different pigment and makes the Fertilizer rod of different colours.
The manufacture method of the Fertilizer rod of the present invention, it is characterised in that comprise the following steps:
(1) dispensing: weigh dispensing by Fertilizer rod formula, described Fertilizer rod formulation weight ratio is: NPK compound fertilizer 80-90, polyvinyl alcohol 8-15, zinc stearate 0.5-1 and glycerol 1-5；
(2) spice: the dispensing weighed is put into fertilizer mixer and fully mixes thoroughly；
(3) extruded: the dispensing mixed thoroughly to be inputted Fertilizer rod forming machine extruded；
(4) drying: extruded Fertilizer rod base is accessed drip pan, reject the returning charge of broken rod, send into drying room hot air drying, baking temperature 45 DEG C-60 DEG C, to water content less than 10%；
(5) packaging: the Fertilizer rod packaging seal that will dry.
The manufacture method of the Fertilizer rod of the present invention, the extruded of described step (3) can also is that compression molding, is added by a certain amount of fertilizer and puts into drip pan drying in mould after extrusion forming.Compression molding device can numerous can letter, made Fertilizer rod shape follows one's bent, and volume of production is changeable, the formula maneuverability of its compound fertilizer, strong adaptability, and practicality is good.
