Description
Technical field
The present invention relates to slow release fertilizer technical field, particularly relate to a kind of anti-caking water-holding compound fertilizer material fertilizer and preparation side thereof
Method.
Background technology
At present, China market agricultural fertilizer material, substantially there are three kinds: a kind of fertile for industrial chemicals, one is fertilizer, also
Have a kind of fertile for industrial chemicals and organic fertilizer mixing；The shortcoming of industrial chemicals: life-time service can cause soil soil property to harden,
Affect plant growth, cause the progressively underproduction；The shortcoming of organic fertilizer is: needed for plant, nutrient is not enough, can not meet crops
The demand produced；Affect crop yield；The shortcoming that mixing is fertile: organic matter and full nutrient in fertilizer formula are conflicting,
This is high, and that are low, such as organic too high levels, produce granule difficulty.It addition, China's Arid&semi-arid area gross area accounts for territory
The 50% of the gross area, China's agricultural is again to use water rich and influential family, and Water Consumption in Agriculture exceedes the 70% of total water consumption, and production efficiency
The lowest, China's annual agricultural water breach is about at 30,000,000,000 m 3, and agricultural water crisis presents and constantly aggravates situation.Soil
Earth water-retaining agent is used alone not only increases work number of times and cost, and because water-loss reducer of soil consumption is the most less, it is difficult to
Fertilizer is fully contacted so that received moisture is difficult to and nutritional labeling generation reciprocal action, largely reduces water-retaining agent
Effect.It addition, the common fertilizer water solublity used at present is the highest, rate of release is very fast, and the release phase is shorter and many
Using totally basal dressing techniques so that fertilizer nutrient rate of release is poor with crop regulation of fertilizer requirement synchronicity, fertilizer nutrient loses
Very big, fertilizer nutrient utilization is relatively low, though and split application method can improve crop different growing nutrient demand, but take a lot of work
Time-consuming, it is not suitable with the requirement of modern agriculture high-efficient development.And, the fertilizer efficiency height in being manured into soil and soil moisture shape
Condition is in close relations, and " with fertile water transfer, promoting fertilizer with water " is highly important rich water control technique in agricultural production.
Mulch film has the effects such as insulation, water conservation, frost protection to crop, and the application of ground membrane technology improves greatly and adds
The yield of crops and benefit, but tradition mulch film is the macromolecular compound of a kind of synthetic, the most hardly
Degradable, after using, place to go is not comprehended soil environment is caused the biggest pollution, affects crop root growth, and the mulch film processed because of
Moist, damaged, the most not reusable edible, only as garbage reclamation, work consuming is time-consuming.
Therefore, being modified fertilizer, improving fertilizer efficiency is to reduce fertilizer use, the effective way increased operation rate.Such as mesh
Front slow-release or control-release fertilizer is exactly one of effective measures improving chemical fertilizer utilization ratio, and slow-release or control-release fertilizer can efficiently control the release of nutrient, prolong
Long fertilizer efficiency period, meet the whole period of duration of crop to the needs of fertilizer nutrient, the utilization rate of fertilizer, minimizing can be improved to greatest extent
The wasting of resources and environmental pollution, to promoting agriculture and forestry volume increase, increasing peasant income, agriculture and forestry sustainable development important role, be
The important development direction of 21 century fertilizer industry.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of anti-caking water-holding compound fertilizer material fertile and
Preparation method.

9, polyvinyl alcohol 8-12, N,N methylene bis acrylamide 0.5-1, water are appropriate.
The preparation method of described anti-caking water-holding compound fertilizer material, comprises the following steps:
(1), by weathered coal drying and be ground to 150-200 mesh, the 1.5-2 times of water taking powder weight adds in reactor, adds powder
End and appropriate potassium permanganate are formulated as 4-8% potassium permanganate solution, stirring oxidation 40-50 minute, are heated to 90-100 DEG C, add
The potassium hydroxide of solution weight part 0.2-0.5%, stirs 30-40 minute at 2200-2500rpm high speed machine, centrifugation, filter
It is 50-60% that liquid is concentrated into moisture content, and filtering residue is stand-by；
(2), by step (1) concentrated solution and polyvinyl alcohol, N, N-methylene-bisacrylamide mix and blend, it is heated with stirring to 40-
React 20-30 minute at 50 DEG C, carbamide is added and is ground to 40-60 mesh, add suitable quantity of water stirring and melt, and reactant liquor mix and blend,
Joining in drying oven, dry 1-2 hour at 80-90 DEG C, cooling crush crosses 200 mesh sieves, standby；
(3), filtering residue, fine perlite, activated carbon mixed grinding being crossed 200 mesh sieves, the citric acid putting into 0.1-0.2mol/L is molten
In liquid, 1-2 hour processed of stirring leaching, stands and removes liquid, and oven drying at low temperature is baked 40-60 minute at 350-400 DEG C, and discharging spray profit water steams
Gas extinguishes cooling to powder body, adds 3-5 times of water stirring extremely suspended shape, adds polylactic acid, and high pressure homogenize stirs, and obtains peplos
Liquid；
(4), by sodium humate, polyacrylamide, ferric ammonium citrate, magnesium sulfate, potassium dihydrogen phosphate mixing, and gross weight 3-is added
The water mixing and stirring of 4 times, obtains nutritional solution；
(5), by Chinese herb residues, plant ash, pine soil co-grinding, nutritional solution, EM microbial inoculum and gross weight 0.3-are added afterwards
After the water of 0.5 times stirs, fermentation 25-35 days of banking up at 32-38 DEG C, stand-by；
(6), by fermentation material being crushed to 80-100 mesh, add chitosan mix and blend, adjustment moisture is gross weight 46-50%,
The ball-type fertiliser granulates of granulator granulation diameter 1-1.2mm, places band high-pressure nozzle and rolling at high temperature of air cooking fluidizes
On bed, coating liquid step (3) obtained repeats to be sprayed at ball-type fertiliser granulates for 3-5 time uniformly by high-pressure nozzle, sends into
Tumbling disk granulator, is simultaneously introduced step (2) and bakes powder, after granulating and forming, within dry 8-10 hour, cools down at 45-50 DEG C, packed
Obtain.
The invention have the advantage that
(1) anti-caking water-holding compound fertilizer material of the present invention adds plant ash, pine soil, weathered coal, active carbon functional composition, increases fertilizer
Material pellet pores, improves granule stability so that fertilizer preventing blocking effect is good, and can stop between fertiliser granulates during use is mutual
Phase adhesion conglomeration, thus ensure that the fertilizer efficiency of fertilizer.
(2) anti-caking water-holding compound fertilizer material of the present invention is also added with conventional bacterial manure and works in coordination with microbial activity with inorganic fertilizer and become
Point, use multilayer coating structure release structures, external sheath liquid-state mulch film functional component, not only there is the sustained release performance of nutrition release,
Serve again water retention, can be that soil provides the multiple resources such as carbon, nitrogen after degraded, stimulate growth and development of plants, increase simultaneously
The resistance of crop, the effect of the nutriture of plant improved, collaborative internal layer bioactive ingredients, further improvement soil knot
Structure, gives full play to fertilizer efficiency, promotes plant growing, improves crop yield.
