Abstract
The invention discloses a leek fertilizer prepared from modified peat and a preparation method thereof. The leek fertilizer is prepared from the following raw materials: peat, 1 mol/L of a sodium pyrophosphate solution, 6 mol/L of a KOH solution, ammonium sulfate, abamectin herb residue, plant ash, potassium sulphate, fermented forage grass, a resin additive and a proper amount of water. Under the precondition of considering the environmental factor, the modified peat used as an additive is added into the fertilizer and simultaneously abamectin herb residue is added so as to prepare the fertilizer. The leek fertilizer is beneficial to protect leek from pest and disease damage. In addition, the adsorption effect of the additive can make the fertilizer to be locked in a certain area so as to protect the environment.
Description
Technical field
The invention belongs to the Technology field of fertilizer, be specifically related to leek fertilizer prepared by a kind of modified turf and preparation method thereof.
Background technology
Humic acid is that plant and animal residues passes through complicated biology, chemical action is formed, account for 50% ~ 80% of total organic matter in soil and hydrosphere ecosystem, it is rich in various active group, can interact with many organic and inorganic things, while it provides nutrient to plant, the behavior of agricultural chemicals in edatope can be controlled.Humic acid of many uses, its application has penetrated into all respects such as industry, agricultural, medical science, environment protection.Natural humic acid is extensively present in soil, river silt, oceanic sediment, brown coal and weathered coal etc., and peat is exactly the important source of one, and the extraction yield how improving humic acid becomes the important direction of of humic acid research now.
The macromolecular basic structure of humic acid is aromatic nucleus and alicyclic ring, ring has the functional groups such as carboxyl, hydroxyl, carbonyl, quinonyl, methoxyl group.He with the metal ion clutch in water, can be conducive to nutritive element and transmits to crop, and can improve spy and allow structure, is conducive to the growth of farm crop.
Nowadays agricultural, plant husbandry have become the important indicator of a national productivity, in order to improve productivity effect, large-scale agricultural, plant husbandry are accelerated to produce, and often cause planting site nutrition to put down weary, and inevitably abuse chemical fertilizer improves production, a large amount of uses of fertilizer, really output can be improved, but fertilizer within the time of plantation, all can not utilize effectively, there is data declaration: the fertilizer component of more than 30% enters soil, river because of rain drop erosion, causes serious pollution.Cause algae " wildness ", fish are because of anoxic mortality, and cause ecological serious unbalance, spend in river regulation every year, the expense of land forming should not be underestimated.
Summary of the invention
The time that the present invention reserves at planting area to improve fertilizer, improve utilization rate of fertilizer, avoid causing severe contamination because rain drop erosion enters physical environment, propose peat to be carried out modification and be used for alleviating the problems referred to above in fertilizer, concrete grammar is as follows:
Leek fertilizer prepared by a kind of modified turf, it is characterized in that, be made up of the raw material of following weight part: peat 20 ~ 25,1mol/L sodium pyrophosphate solution 5 ~ 7,6mol/LKOH solution 8 ~ 12, ammonium sulfate 45 ~ 60, avermectin slag 5 ~ 10, plant ash 20 ~ 25, potassium sulfate 50 ~ 60, fermentation herbage 25 ~ 30, resin additive 3 ~ 4 and appropriate water;
Described resin additive is made up of the raw material of following weight part: polyvinyl alcohol 12 ~ 16,15% formaldehyde solution 3 ~ 5, turps 4 ~ 6, stearic acid 1.5 ~ 3,40% sodium peroxide solution 8 ~ 10, cyclodextrin 3 ~ 6 and appropriate water; Preparation method is: be that solvent joins in reactor with Virahol, be blended into the water dilution of 5 ~ 6 times of its weight parts, then add polyvinyl alcohol and 15% formaldehyde solution, be warming up to 70 ~ 80 DEG C, be stirred to and dissolve completely, then 35 ~ 40 DEG C are cooled to, maintain 1 ~ 1.5h to be polymerized, be blended into turps, stearic acid after completing, after stirring and dissolving, be blended into other remaining component, finally stir into oily liquid, be incubated for subsequent use.
A preparation method for leek fertilizer prepared by modified turf, is characterized in that, comprise following step:
(1) peat is carried out ball milling 30 ~ 40min, cross 60 mesh sieves, then put and dry 3 ~ 4h under 105 ~ 120 DEG C of conditions in an oven, become granular pulvis;
(2) pulvis described in (1) is placed in reaction vessel, adds the water of 2 ~ 3 times of its weight parts, then add 1mol/L sodium pyrophosphate solution and 6mol/LKOH solution simultaneously, be placed in ultrasonic cleaning machine, power 0.75kw, is incubated 80 DEG C of effect 60 ~ 80min, regulates pH to partial neutral;
(3) resin additive is joined in the total material described in (2), stir, finally control solid carbon dioxide and divide, again carry out the particulate state being ground into 60 mesh sieves;
(4) mix ammonium sulfate, potassium sulfate, add water-wet to water content 80 ~ 90%, add the granule modified peat described in (3), be heated to 70 ~ 80 DEG C and carry out chelating 20 ~ 25min, finally add other remaining component, granulation after mixing.
Starting point of the present invention is the adsorption effect utilizing humic acid, peat is adopted to be that a kind of humic acid fertilizer prepared by raw material, but not only containing a large amount of humic acid compositions in peat, also there is certain impurity, some free radicals and functional group hinder humic acid release ontological idea of freedom base, have a strong impact on the adsorption effect of humic acid in peat, the extraction carrying out humic acid to peat can improve the efficiency of modified turf.
By to the pre-treatment of peat before extracting, can improve the extraction yield of humic acid in peat, invention compared for different pretreatments method by experiment, atmospheric oxidation pre-treatment and ultrasonic pretreatment useful to extraction yield, but promote DeGrain.The extraction yield obtained after adopting nitric acid to carry out pre-treatment to test sample is best.
No matter adopt which kind of pretreatment process, with Na

7when+KOH makes alkali extracting solution, extraction effect is best.The molten analysis of alkali shows, adds 0.1mol/LNa
4p
2o
7with alkali liquid-phase mixing, the extraction yield of humic acid is promoted significantly, and the molten effect of alkali increases along with the increase of alkali concn.
Peat is the middle atmospheric swamp ground product formed through thousand, be rich in beyond humic acid, also containing organic and talc particles, the fiber impurity of humic acid and plant decay is wrapped in the surface of stone flour with a kind of form of colloid, the peat that to form, if adopt the extracting method believed, original peat structure can be destroyed, although humic acid obtains a certain amount of liberation, but be easy to depart from original body, favourable in water, although or mineral fertilizer element can be adsorbed, but be difficult to the effect playing sedimentation, still cannot improve the problem of fertilizer loss, so on this basis, after invention is extracted accordingly to humic acid, with polyvinyl alcohol, modified peat-resin particle is prepared in formaldehyde effect, make to possess certain adhesive characteristics between peat body, that the humic acid composition extracted sticks to each other to a certain extent and between peat talc particles, have the characterization of adsorption to chemical fertilizer concurrently simultaneously.
Beneficial effect of the present invention: leek can be cut for a long time as one, for the production of agricultural-food, long-term fixing plantation can badly influence self resistance, easily corrode by insect, prevention subterranean pest-insect, preventive effect can not only be improved, extend the lasting period, and it is very safe to leek root, the present invention utilizes the peat of modification to add in fertilizer for additive under the prerequisite considering environmental factors, add avermectin slag simultaneously and together make fertilizer, useful protection leek is not by the threat of disease and pest, the efficacy of adsorption that additive possesses simultaneously can make fertilizer be locked in certain locality protection environment.
