Abstract
The invention relates to a novel polypeptide magnetized compound fertilizer, which comprises the following ingredients in percentage by mass: 0.1 percent to 0.5 percent of polypeptide, 3 percent to 5 percent of pyritic ash and 95 percent to 97 percent of compound fertilizers. After the ingredients are mixed, the pyritic ash is subjected to magnetic excitation, and the material center point magnetic field intensity is 100 to 500mT. Byproducts (pyritic ash) in the potassium sulfate compound fertilizer production process are integrally utilized, the product cost is low, the benefits are high, and the market prospects are wide.
Description
Technical field
The present invention relates to the chemical fertilizer field, be specifically related to a kind of novel polypeptide magnetic compound fertiliser.
Background technology
Peptide (peptide) is that a-amino acid links together with peptide chain and the compound that forms; It also is the intermediate product of proteolysis, and the common compound that is formed by 10～100 amino acid molecular dehydrating condensations is polypeptide, and their molecular weight is lower than 10; 000Da (Dalton; Dalton), can see through semi-permeable membranes, do not precipitated by trichoroacetic acid(TCA) and ammonium sulfate.Polypeptide has very strong biological activity making the object internal memory, relates to crop growth, growth, cell fission, information transmission, immune control, anti-ageing, physiological clock rule and molecular evolution etc.Numerous research documents prove, inject bioactive peptide to crop, can adjust each position speed of growth of crop; Crop yield is had certain effect, and the polypeptide that uses at present mainly is a poly-aspartic-acid, adds in fertilizer as synergistic agent; In the composite fertilizer of urea and high tower pellatizer, generally use at present; And in the cylinder of most of producer widespread use, spray granulating technology, after polypeptide adds composite fertilizer's slip, in composite fertilizer's drying course easily under high temperature action coking lose activity; If add in fertilizer oven dry back; Because polypeptide is a kind of viscous liquid, causes fertilizer agglomeration easily,, above reason has bigger limitation owing to causing the production of polypeptide composite fertilizer.
The sulfuric acid that uses in the compound potassium sulfate fertilizer production is generally made raw material with sulfurous iron ore, and sub product is the sulfurous iron ore ash, and the staple of sulfurous iron ore ash is a Z 250, is good magnetic carrier.Lot of domestic and foreign research proof, magnetic carrier are blended in the suitable excitatory formation magnetic fertilizer of process in the fertilizer, and magnetic fertilizer has certain effect to increasing crop yield.After the sulfurous iron ore ash is levigate, the mutual adhesion that reduces between the compound fertilizer granules had certain effect.And the sulfurous iron ore ash that produces in the present compound fertilizer production technology can not get comprehensive utilization, but handles as refuse, has obviously formed a kind of wasting of resources.
Summary of the invention
The present invention overcomes the technical deficiency that existing polypeptide composite fertilizer exists, and the invention provides a kind of novel polypeptide magnetic compound fertiliser and production technique thereof.
The technical scheme that the present invention adopts is: a kind of novel polypeptide magnetic compound fertiliser; Comprising quality is: the composite fertilizer of the polypeptide of 0.1%-0.5%, the sulfurous iron ore of 3%-5% ash, 95%-97%; Mix back sulfurous iron ore ash and swash through magnetic, material central point magneticstrength is 100-500mT.The fineness of described sulfurous iron ore ash is 100～200 orders.
Above-mentioned described novel polypeptide magnetic compound fertiliser complete processing is: composite fertilizer is carried out granulation by traditional technology, mix with liquid polypeptide after being cooled to normal temperature, make polypeptide evenly attached to the compound fertilizer granules surface; In the composite fertilizer of mixed polypeptide, add the sulfurous iron ore ashes and mix, make the sulfurous iron ore ashes, prevent that adjacent particle from cohering evenly attached to the polypeptide appearance; Filter out satisfactory compound fertilizer granules and carry out magnetic and swash through screening plant, finally obtain the novel polypeptide magnetic compound fertiliser.
The present invention and compared with techniques in the past have following beneficial effect:
(1), fertilizer cooling back adds polypeptide, causes between fertiliser granulates and coheres each other, utilizes powdery sulfurous iron ore ash to stick on the fertiliser granulates, solves intergranular adhesion problems.
(2), the sulfurous iron ore ash that sticks to fertiliser granulates surface is good magnetic carrier, after appropriateness is excitatory, forms polypeptide and magnetize compound potassium sulfate fertilizer.Prove with field experiment that through potted plant staple crops such as wheat, corn, cotton are used polypeptide magnetization compound potassium sulfate fertilizer than common compound potassium sulfate fertilizer obvious effect of increasing production, amount of increase in production is 6.2～8.5%.
(3) sub product in the compound potassium sulfate fertilizer production technique (sulfurous iron ore ash) is fully utilized, product cost is low, high efficiency, and market outlook are wide.
