Description
Technical field
The present invention relates to soil improvement fields, and in particular to a kind of cobalt compound and its preparation method and application.
Background technology
With the structural adjustment of China's animal husbandry, the cultivation of phytophage domestic animal increases rapidly, to good herbage demand
Also it is continuously increased, and China's soil texture is polynary, situation is complicated, and herbage quality is difficult to ensure that.In order to ensure the quantity of herbage and
Quality needs to improve herbage, and existing soil conditioner passes through sprinkling mostly using the composite fertilizer rich in N, P, K
Mode is added in soil, but the mode of this application be easy to cause sprinkling concentration of fertilizer and excessively concentrates, in plant roots and stems or leaf
On piece remains, and be easy to cause the problems such as burning kind hinders root, causes herbage survival rate low.Therefore, for the additive of soil improvement or
Fertilizer becomes the research hotspot of this field.
It is by certain ratio with water by cobaltous sulfate to have the method mainly taken plant application cobaltous sulfate in currently available technology
It is sprayed, such as horse is rushed after example dissolving《Influence of the Leaf Surface Spurting Cobalt Sulfate to Fresh Forage Yield of Alfalfa and quality》In point out from fresh grass
High 20 centimeters of stem spray the solution of various concentration cobaltous sulfate, can increase Fresh Forage Yield of Alfalfa and improving quality, but should
The effect that long-acting slow-release is not achieved in method can only be interrupted that apply labor intensity big in short term, and as moisture evaporation part cobalt salt can be residual
It stays in plant surface the effect fully absorbed is not achieved and can be eaten by mistake by animal, animal cobalt is caused to be poisoned.Also there is spray in this method
The problem of concentration is not easy to control is spilt, excessive concentration plant is difficult survival, and concentration is too low and enough cobalt members can not be supplemented to soil
Element increases cost instead, and therefore, applying cobaltous sulfate this technological means into soil and being not particularly suited for the pasture of large area makes
With.
Invention content
To make up the deficiencies in the prior art, the present invention provides a kind of polynary cobalt chemical combination for the soil improvement of large area pasture
Object.The compound has special features of shape, in a sustained manner penetrates into trace element in soil, improves soil knot
Structure.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of polynary cobalt compound, including active component and support carrier, the active component is by CuSO4·5H2O and
Cobalt salt forms, and the support carrier is the one or more in clay or kaolin.The active component and support carrier
Mass ratio be 1:20~1:30.The cobalt compound is the ball-type of diameter 5-7mm.
The preferred CoSO of the cobalt salt4·7H2O、CoCl2·6H2O or Co (NO3)2·6H2The one or more of O.
Wherein, CuSO4·5H2The mass ratio of O and cobalt salt is (0.5-2)：1.
The preparation method of above-mentioned cobalt compound includes the following steps：
S1. active component and support carrier are crushed to 150-400 mesh with pulverizer respectively；
S2. the raw material after step S1 is crushed, which is added in mixing machine, mixes 1-3h；
S3. mixed raw material is added to by feeder in granulating disc, is molded in rotating circular disk, rotating circular disk
Rotating speed is 5-30rpm/min；
S4. the ball-type material for granulating disc of dishing out is dried, first stage drying condition is：40-70 DEG C of drying
4-8h, second stage drying condition are：70-100 DEG C of drying 5-8h；
S5. the material after drying with vibration separation screen is sieved, the powder collection of diameter 5-7mm is packed.
Preferably, in the step S3, the matter of the liquid component distributor of granulating disc, water and material is injected water into
Amount is than being 1:4~1:6, when the disk rotates, equably for sprinkle on material, the water capacity for keeping material in disk is 30% to water
~60%.
As the preferred embodiment of the invention, by fine powder of the diameter less than 5mm in the step S5 or diameter more than 7mm's
Particle recycling, which is packed into pulverizer, to be crushed.
Application of the above-mentioned polynary cobalt compound in the soil improvement of pasture is claimed in another object of the present invention.
The present invention explores the composition of ball-type cobalt compound active component and the active component is matched with the reasonable of support carrier
Than the cobalt salts such as copper sulphate, cobaltous sulfate are crystalline hydrate, its own contains the crystallization water, with the continuous variation of temperature, crystallization
Water is detached from metal ion, can also absorb water after the crystallization water all loses, be again transformed into crystalline hydrate, therefore, selection knot
Brilliant hydrate contributes to the slow release effect of moisture and metal ion into soil as raw material of the present invention.Copper ion and cobalt ions association
Same-action promotes soil texture more perfect, soil is made to be more suitable for the growth of herbage.Active component is determined with support carrier proportioning
The performance of cobalt compound, the high support vector contg of viscosity are excessive or very few not easily molded；The temperature and time of preparation is determined
The forming stability of ball-type cobalt compound is determined.Temperature is excessively high, and solution rate is too fast, and ball-type cobalt compound is unstable, dissolving speed
Degree is slow, causes cobalt content in compound inadequate.Therefore, rational raw material proportioning and process conditions can just make active component and support
Carrier is sufficiently mixed balling-up.
Ball-type cobalt compound prepared by the method for the present invention has the characteristics that, good fluidity more uniform than great, particle, Bu Hui
Plant surface remains, and does not corrode plant, and it is low to be easy to sow labor intensity, is used suitable for large area pasture.Using clay or height
Ridge soil makes it have good water lock function as support carrier, one side good leak tightness；On the other hand, raw material can be increased
Between degree of adhesion, contribute to cobalt mixture be molded spheroiding.The mixture of the present invention can make the leguminous forages such as alfalfa
The long-acting absorption of energy, makes it increase production and improve productivity, while improve amount containing cobalt in herbage, increases domestic animal appetite, effectively domestic animal is avoided to occur
Cobalamin deficiency improves growth, development, breeding and the immunity function of poultry, and the pasture available for large area uses.
Compared with prior art, the invention has the advantages that：
The present invention is prepared for a kind of cobalt compound of ball-type, which is slowly discharged cobalt ions by way of sustained release
Into soil, COBALT IN SOIL BY constituent content can be kept for a long time, it is good that product using the present invention obtains the soil texture in pasture
Improve well, be improved the quality of herbage especially leguminous forage, preparation process of the invention is simple, need not additionally add
Chemical reagent, the chemical substance for having pollution without heavy metal and to environment, environmentally protective, maintaining ecological balance.
