Abstract
The invention relates to a bio-char based slow releasing compound fertilizer, which comprises the following raw materials in parts by weight: 60-80 parts of straw, 4-5 parts of adhesives and 25-40 parts of compound fertilizers. The preparation method comprises the following steps: adding water into the 25-40 parts of compound fertilizers to obtain a paste fluid; adding the 60-80 parts of straw into the obtained compound fertilizer paste fluid and stirring for 30 min; granulating and drying the straw added paste fluid and the 4-5 parts of adhesives to obtain the required bio-char based slow releasing compound fertilizer. According to the invention, the bio-char based slow releasing compound fertilizer and the preparation method thereof are simple in technology, short in production cycle, wide in source of raw materials, easy to degrade, high in potassium content and low in equipment requirement.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly a kind of biological carbon back slow-release compound fertilizer and preparation method thereof.
Background technology
Charcoal is a word of newly making, and by English bio-charcoal translation, is come, and is also translated into biomass charcoal or biomass char.Charcoal is that biomass (are mainly abandoned biomass, biomass are general designations of biological organic materials) thermochemistry under anoxic or micro-Oxygen Condition (comprising thermo-cracking and gasification) transform after solid product, be mainly used in the powdered granule charcoal of agricultural soil improvement, it is similar to traditional charcoal, bamboo charcoal and gac on physical structure and chemical attribute.Charcoal is powdered granule in form, color is black, on composition, contain the carbon of 40%-75%, wherein most carbon is the carbon of microorganism utmost point difficult degradation, belong to the stacking carbon of aromatic nucleus, contain hydroxyl, carboxyl residue, and the mineral substance that contains different amounts, be mainly calcium, magnesium, iron and other trace elements.On microscopic pattern, be cellular structure, the hole that tool is abundant and huge surface area, can absorb own wt 5-6 moisture doubly.In chemical property, mostly present alkalescence, can Liquidity limit and negatively charged ion, there is macroion exchange capacity very.The unique physical chemical property of charcoal can exchange adsorption fertilizer and soil nutrient, improve water retention in soil, can improve soil pH, its pore texture can be soil beneficial microorganism, particularly MF bacterium (Mycorrhizal Fungi: mycorrhizal fungi) habitat, so, charcoal can improve soil physical chemistry and microorganism active, fertilizing soil, its refractory organics carbon can be preserved hundreds of to thousands of years in soil, so being manured into soil, charcoal can play solid carbon or carbon remittance effect, it both can make soil improvement agent, also can be used as solid carbon agent, all right as fertilizer sources slow-released carrier, therefore, whole world research and focus of attention material since the 90's of last century, have been become.
Now also there is relevant design, CN102424649A as open in Chinese patent, a kind of production method of charcoal base slow-release nitrogen fertilizer, comprises the following steps: maize straw or the useless limb wood chip of apple tree, the charcoal obtaining after the hot cracked or gasification of wood chip; By charcoal and ammonium nitrate solution or the mixing of urea-ammonium nitrate solution, fully stir post-drying, or add the binding agent of total amount 1 ~ 3%, be sent to granulating system granulation, then dry and can obtain charcoal base slow-release nitrogen fertilizer product.
But above-mentioned its tooling cost of employing gasifying stalk is high, and equipment requirements is high, is unfavorable for spread.
Summary of the invention
High in order to solve existing biological its tooling cost of carbon back slow-release compound fertilizer gasifying stalk, equipment requirements is high, is unfavorable for spread, the invention provides a kind of biological carbon back slow-release compound fertilizer and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of biological carbon back slow-release compound fertilizer, its component, in weight fraction, comprises 60-80 part stalk, 4-5 part cakingagent, 25-40 part composite fertilizer.
A preparation method for biological carbon back slow-release compound fertilizer, preparation process is as follows:
(1) 25-40 part composite fertilizer Jia Shui is made to paste fluid;
(2) to the composite fertilizer's paste fluid making, add 60-80 part stalk to stir 30 minutes;
(3) the lotion and the 4-5 part cakingagent granulation oven dry that add stalk are made to required biological carbon back slow-release compound fertilizer.
The invention has the beneficial effects as follows: technique is simple, with short production cycle, raw material sources are wide, are easy to degraded, and potassium content is high, and equipment requirements is low.
Embodiment
To describe the present invention in detail with specific embodiment below, illustrative examples wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.
Embodiment 1, makes paste fluid by 25 parts of composite fertilizer Jia Shui; To the composite fertilizer's paste fluid making, add 60 parts of stalks to stir 30 minutes; The lotion and the 4 parts of cakingagent granulations oven dry that add stalk are made to required biological carbon back slow-release compound fertilizer.
Embodiment 2, makes paste fluid by 40 parts of composite fertilizer Jia Shui; To the composite fertilizer's paste fluid making, add 80 parts of stalks to stir 30 minutes; The lotion and the 5 parts of cakingagent granulations oven dry that add stalk are made to required biological carbon back slow-release compound fertilizer.
Embodiment 3, makes paste fluid by 30 parts of composite fertilizer Jia Shui; To the composite fertilizer's paste fluid making, add 70 parts of stalks to stir 30 minutes; The lotion and the 5 parts of cakingagent granulations oven dry that add stalk are made to required biological carbon back slow-release compound fertilizer.
The present invention not only technique is simple, with short production cycle, and raw material sources are wide, is easy to degraded, and potassium content is high, and equipment requirements is low.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
