Abstract

The invention discloses an organic fermentation absorption controlled release fertilizer and a preparation method of the organic fermentation absorption controlled release fertilizer. The organic fermentation absorption controlled release fertilizer comprises, by weight, 20-30 parts of cinnamon wood chips, 35-50 parts of crop straw, 20-30 parts of dry cow dung, 15-20 parts of biogas residue, 25-35 parts of fruit tree trash, 15-25 parts of lotus pool sludge, 15-20 parts of potassium sulfate, 2-3 parts of EM fungicide, 16-22 parts of phosphorous pentoxide, 20-25 parts of ground phosphate rock, 15-25 parts of ammonium sulfate, 8-12 parts of calcium bicarbonate, 4-5 parts of binder and moderate water. Different from the characteristics of original controlled release fertilizer, the organic fermentation absorption controlled fertilizer is not of an integral spherical membrane structure, but utilizes the membrane which is hard to decompose for the controlled release. Therefore, the organic fermentation absorption controlled release fertilizer is easily loosen after fertilizer applying, uniform in distribution, capable of playing the controlled release function according to the absorption capacity of activated carbon, more uniform in function and effect and more comprehensive in vegetation absorption.

Description

A kind of organic fermentation absorption class slow release fertilizer and preparation method thereof

Technical field

The invention belongs to the Technology field of fertilizer, be specifically related to a kind of organic fermentation absorption class slow release 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.
