Abstract

The invention provides a fertilizer combining organic carbon and inorganic nutrients. The fertilizer is characterized by being prepared from the following raw materials in parts by weight: 20-30 parts of pampas grass straws, 15-20 parts of sorghum straw, 15-20 parts of bamboos, 5-10 parts of quartz sand, 2-3 parts of a 1mol/L hydrochloric acid solution, 25-35 parts of kaolin, 15-20 parts of potassium sulfate, 6-9 parts of magnesium sulfate, 12-17 parts of ammonium carbonate, 14-20 parts of ammonium dihydrogen phosphate, 14-18 parts of potassium humate, 4-5 parts of a bonding agent and an appropriate amount of water. The fertilizer is prepared by taking the bamboos, the pampas grass straws and the like which have relatively high cellulose contents as raw materials, grinding the raw materials by the quartz sand having a certain particle size to obtain organic plant particles having an appropriate particle size, then performing high-temperature closed carbonization to ensure that the obtained particles are uniform in size, washing away impurities by using diluted acid to ensure that the particle carbonized components are more porous and are stronger in adsorptivity, then mixing the particle carbonized components with powder chemical components, performing adsorption after full contact, and finally mixing the kaolin as a base material to perform granulation. Compared with a common straw carbonized fertilizer, the fertilizer provided by the invention is stronger in adsorptivity, obvious in slow-release effect and more complex in process.

Description

A kind of Organic carbon is in conjunction with inorganic nutrients fertilizer and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of Organic carbon in conjunction with inorganic nutrients fertilizer and preparation method thereof.

Background technology

Coated fertilizer is also known as coated fertilizer, film fertilizer.The fertilizer of quick-acting chemical fertilizer granule is wrapped up with semipermeability or opacity film substrate.Filmogen has plastics, resin, paraffin, polyethylene and elementary sulfur etc., and the object of coating is that the available nutrient of coated fertilizer the inside after being manured into soil is discharged, lentamente to extend fertilizer efficiency.Rate of release is decided by coating kind, thickness, particle diameter, fertilizer solvability, the soil moisture, soil moisture content and soil microbial activities etc.Be applicable to that economic worth is high, breeding time is long, fertilizer requirement is large but the crop of inconvenient split application, and nutrient is easy to that the temperature of leaching loss is high, area of heavy rainfull or irrigation region, especially on the sand loam soil that quality is light.

The coating agent of the fertilizer that our company produces is made up of two portions mostly, a part is stone flour class base-material, another part is binding agent, some pore-forming materials may be added, as organic pore-forming agents starch, agar, jelly powder, sodium alginate etc., also have inorganic pore-forming material as urea, ammonium chloride, sodium bicarbonate etc., after decomposes, leave multi-hole type surface, ventilative, circulation, is convenient to discharge inner nutrient.

Stone flour class base-material is mostly by vermiculite power, limestone powder, cement, terra alba, lime powder, starch, quartz powder etc., effect is to provide stable support, ensure internal loose structure, disperse after being conducive to fertilizer cracking evenly, be unlikely to clustering phenomena, can prevent fertilizer to make moist caking in addition, be unfavorable for fertilising, in addition to the above, stone flour is the comprehensive inorganic mixture of the elements such as a kind of calcium-magnesium-containing mostly, also have and improve soil property, the effect of keeping soil from packing together.

Another kind of is binding agent, mainly the emulsion part of resin monomer polymeric part and oils, tensio-active agent and stone flour composition is composite forms, here be resene monomer styrene solution, utilized the dissolve with ethanol after dilution before this, then linking agent ethylene glycol dimethacrylate crosslinking polymerization is added together, it is to be noted that styrene monomer should not expose in atmosphere for a long time; Second is mixing sodium lauryl sulphate, tea tree oil, Zinc Gluconate and water, while oil and water are wrapped to form profit multipolymer by surfactant sodium lauryl sulphate by Zinc Gluconate admixture wherein, make emulsion, carry out composite with aforesaid thin polymeric solution, finally make the binding agent with bond effect, be characterized in intimate pollution-free, bond effect is good, suitable controlled release concentration and the release speed of the adjustable fertilizer of membrane wrapping thickness in soil.
