Description
Technical field
The invention belongs to Crop fertilizer technical field, is related to fertilizer, soil conditioner, and in particular to one kind prevents fertilizer
Soil conditioner of caking and preparation method thereof.
Background technology
Middle-and-low-yielding fields soil erosion in China's accounts for the 2/3 of total land area at present, foodstuff production-increasing potential of improving the low and medium-yield farmland
It is huge.It is the effective way improved the low and medium-yield farmland using soil conditioner, it can promote the formation of soil granular, improved soil
Structure, build up fertility, improve soil water-reataining fertilizer-keeping, improve grain yield.Soil block is caused by mainly due to moisture, and
Moisture in soil mostlys come from capillary, and this part is also referred to as Free water, and this portion is very easily adsorbed in the inside of soil
Divide moisture, also one kind is the crystallization water, is existing moisture, and moisture intrinsic in fertilizer molecule in itself inside fertilizer, is
Inside occurs caused by chemically reacting.Fertilizer can also be deformed so as to easily cause to lump, outside under external pressure effect
Portion's pressure makes internal structure even closer, and crystal is easily deformed, under too high temperature storage, the humidity step-down of fertilizer, this
Fertilizer agglomeration can be caused.
Polymeric soil texture modifier polyacrylamide is at present using one of more soil conditioner, pertinent literature
Also it is more such as China Patent Publication No.：CN102604646A but polymeric soil conditioner production technology and raw material sources requirement compared with
Height, it is expensive, its widespread adoption is limited, limits the popularization of such soil conditioner to a certain extent.It is high except more than
Beyond molecule soil conditioner, natural soil improved materials because it is cheap, the content of organic matter is high, agricultural production experiment in

Preferably, the modifying agent is mixed using high pressure spray pattern with fertilizer, and dosage is 5-8g/kg fertilizer.
A kind of preparation method for the soil conditioner for preventing fertilizer agglomeration, is comprised the following steps that：
1) vegetable oil is put into 50-55 DEG C of water-bath and heated, non-ammonium type surfactant is dissolved in water, is added into
In vegetable oil, continue stirring 30-40min and mixed completely with the solution of surfactant to oil, obtain prosparol；
2) vermiculite, the dregs of fat and polyacrylamide are put into high speed dispersor, are dispersed with stirring 8-10min, then in three batches
Biosurfactant is added, the amount of sequentially adding is 1/4,1/2 and 1/4, and it is 5-8min that the time is dispersed with stirring after adding every time,
10-15min, with 10-15min, obtain compound；
3) by above-mentioned compound, it is added in prosparol, is dispersed with stirring 15-20min, the soil of fertilizer agglomeration must be prevented
Earth modifying agent.
Compared with prior art, present invention has the advantages that:
1. the present invention is used using vegetable oil and non-ammonium salt class surfactant emulsifies as base-material, having reduces surface
Power, the effect of lubrication prevent the caking of fertilizer, and cost is low, green.
2. the vermiculite of a hair addition, polyacrylamide and the dregs of fat, having improves soil texture, improves the work of soil nutrient
With, inorganic and organic combination, not only there is performance complement, also with simple production process the characteristics of.
Embodiment
Below by the description to embodiment, it is described in further detail, to help those skilled in the art to this hair
Bright inventive concept, technical scheme have more complete, accurate and deep understanding.
Embodiment 1
A kind of soil conditioner for preventing fertilizer agglomeration in the present embodiment, is made up of following quality accounting component：
Preparation method comprises the following steps that：
1) vegetable oil is put into 50 DEG C of water-baths and heated, non-ammonium salt class surfactant Polysorbate B is dissolved in water, will
It is added in vegetable oil, is continued stirring 35min and is mixed completely with the solution of surfactant to oil, obtains prosparol；
2) by the relative molecular mass of the vermiculite of 200 mesh, the rape dregs of fat of 200 mesh of drying and 200 mesh be 9,000,000 it is poly-
Acrylamide is put into high speed dispersor, is dispersed with stirring 10min, is then added biosurfactant in three batches, sequentially adds
1/4,1/2 and the 1/4 of total amount, high-speed stirred jitter time is 8min, 15min and 15min after adding every time, obtains compound；
3) by above-mentioned compound, it is added in prosparol, in high speed dispersor, scattered 20min, must be prevented at a high speed
The soil conditioner of fertilizer agglomeration.
Embodiment 2
The present embodiment preparation method with embodiment 1, unlike：A kind of soil for preventing fertilizer agglomeration changes in the present embodiment
Good dose, it is made up of following quality accounting component：
Embodiment 3
The present embodiment preparation method with embodiment 1, unlike：A kind of soil for preventing fertilizer agglomeration changes in the present embodiment
Good dose, it is made up of following quality accounting component：
By branch, separately experiment carries out performance test to modifying agent prepared by embodiment.
1. prevent caking from testing：Quantitative Chemical Mixed Fertilizer is weighed, embodiment 1-3 modifying agent is sprayed by 8g/kg fertilizer high pressure
To the surface of Chemical Mixed Fertilizer, modifying agent is set uniformly to be wrapped in Chemical Mixed Fertilizer surface；The sample made is labelled, carry out heap compacting
Test, the Chemical Mixed Fertilizer of control group does not spray modifying agent.The actual stacking pressure situation of chemical fertilizer in factory is simulated using big bag heap platen press, will be blended
The Chemical Mixed Fertilizer sample of anticaking agent, which is put into woven bag, to seal, and is 50kg per Bag Material quality, every 10 bags pile 1 pile, are checked after 30d
Caking situation.Caking rate=caking Chemical Mixed Fertilizer quality/net quality × 100% of Chemical Mixed Fertilizer.Test result shows, the caking of contrast groups
Rate is 20.1%, and embodiment 1-3 caking rate is respectively 9.2%, 10.4%, 12.3%, and caking rate is much smaller than contrast groups.This is
Because the vegetable oil after emulsification greatly reduces the surface tension of Chemical Mixed Fertilizer, Chemical Mixed Fertilizer is prevented from caking.
2. the test of soil improvement：Modifying agent prepared by the formula of embodiment 1 for selecting caking rate minimum carries out soil function
Test, by national sector standard NY525-2012 requirement, organic matter is determined using potassium bichromate-sulfuric acid oxidation Outside Heating Method
Content, full dose distillation titration measuring nitrogen content, P-V-Mo Yellow photometry measure phosphorus content, flame spectrophotometric determination potassium content.
Water absorption and evaporation capacity are determined with weight method.During water suction, weigh, saturation when weight difference is less than 0.5g, stop during the morning and evening 10 daily
Water suction.Taken out from disk and place 8 hours, after bulk water oozes out from bottom, dried, it is 35 DEG C to control temperature, relative humidity
For 70%, daily sooner or later 10 when weigh, until weight difference is less than 0.5g evaporations and terminated.Test result shows, organic matter 70.3%,
Nitrogen 7.1%, phosphorus pentoxide 2.8%, potassium oxide 0.41%, water absorbent rate 3.4, the 5th day water retention 0.82.
The present invention is exemplarily described above in conjunction with specific embodiment, it is clear that present invention specific implementation is not by upper
The limitation of mode is stated, if the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or
It is not improved by the present invention design and technical scheme directly apply to other occasions, protection scope of the present invention it
It is interior.Protection scope of the present invention should be determined by the scope of protection defined in the claims.
