Description
Technical field
The present invention relates to fertilizer processing technique field, particularly relate to a kind of water-retaining type oils and fats coated slow-release Oryza sativa L. fertilizer and
Preparation method.
Background technology
Slow release fertilizer is that after fertilizer imposes on soil, fertilizer nutrient discharges a class fertilizer slowly than conventional water soluble fertilizer, its
Coated fertilizer is varied, has the most applied and generally can be divided into inorganic matter, Organic substance two with the coated fertilizer studied
Class.At present, the membrane material of the film-coated and slow release fertilizer of industrialized production is mainly based on synthetic high polymer resin, and uses fluid bed to spray
Coating, complex process.Although slow-release fertilizer is worldwide achieved with bigger development, but owing to commercially available price is common fertilizer
3-8 times significantly limit popularization and application, therefore develop new and effective cheap release-controlled coated material be solve ask
The key of topic.In China, waste grease is also referred to as waste oil, hogwash fat etc., due to the cost of waste grease recycling
Higher, a large amount of waste greases only have small part to be sent to chemical plant to make fatty acid and soap.In recent years, government strengthens useless food
By the sound of oil management legal system and specification, the research utilizing waste in-ore rate to produce the new forms of energy such as biodiesel becomes focus,
But owing to waste in-ore rate free fatty acid content is high, and the degree of becoming sour differs greatly, and is used for producing biodiesel and yet suffers from one
A little technical barriers.Waste oil is readily available, degradable in soil, pollution-free, and the applied research at agriculture field rarely has report.Cause
This, the coated fertilizer that and slow release cheap with waste grease for development of raw materials can be excellent, the offer one that efficiently utilizes for waste oil can
The agricultural reutilization channel of row has wide market prospect.
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 water-retaining type oils and fats coated slow-release Oryza sativa L. is fertile
Material and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of water-retaining type oils and fats coated slow-release Oryza sativa L. fertilizer, is prepared by the raw materials in:
Waste grease 20-22, iodine 0.05-0.06, Talcum 10-11, fish scale 100-110, carbamide 80-85, Caulis et Folium Oryzae 20-22,
Rice chaff 19-20, potassium fulvate 0.4-0.5, zinc methionine 0.3-0.4, auxin 0.1-0.2, yeast waste liquor 5-6, sodium alginate
2-3,0.4mol/L sodium hydroxide solution 800-820, glutaraldehyde 5-6, strong aqua ammonia are appropriate, microbial germ powder 0.4-0.5, bentonite
18-20。
The preparation method of described oils and fats coated slow release fertilizer, comprises the following steps:
(1) adding iodine in waste grease, after being heated to 180 DEG C under nitrogen protection, isothermal reaction 2.5 hours, continues to be passed through
Nitrogen is made protection standing and is cooled to 22-24 DEG C, obtains conjugation modified grease；
(2) by Talcum grinds, make particle diameter reach 0.01mm, obtain Pulvis Talci；
(3) fish scale is washed surface impurity, dry, add after 0.4mol/L sodium hydroxide solution soaks 30 minutes and take out, use
Distilled water wash 2-3 time, dries, pulverizes, and crosses 100 mesh sieves；
(4) step (3) gained material is added the distilled water of 20-22 times, add strong aqua ammonia regulation pH to 7.6, ultrasonic disperse 10 minutes,
Add carbamide, stir 2 hours at 30 DEG C after dissolving, add glutaraldehyde, continue stirring 2 hours, then carry out sucking filtration, gained
It is deposited at 45 DEG C and is dried 48 hours；
(5) Caulis et Folium Oryzae, rice chaff being pulverized, regulation to the water content that adds water reaches 40-45%, adds microbial germ powder, heap vexed fermentation 25-
30 days, once, the gained material raw material unused with step (4) gained material and above-mentioned technique mixes to be made the turning of 5-6 days period
Grain, is dried to constant weight at 40 DEG C, obtains fertilizer kernel；
(6) conjugation modified grease is mixed with Pulvis Talci, be sprayed on fertilizer core surface, be dried, to obtain final product.
The invention have the advantage that waste grease is added catalysis of iodine reaction by the present invention, add conjugated double bond quantity so that it is
Only needing room temperature the most curable during peplos, Talcum is worn into fine powder, the hole existed between inorganic particle and organic membrane can be as supporting
The passage that subrelease is put, and the present invention by after fish scale soaking with sodium hydroxide degumming generate hydroxyapatite there is loose structure,
Can as carrier by Absorption for Urea in duct, then the slow release effect of carbamide, hydroxyl simultaneously can be improved with glutaraldehyde cross-linking embedding
Base apatite also has biodegradation character, and gained catabolite is phosphate anion and calcium ion, and these elements can be made
Thing re-absorption, will not produce destruction, additionally, the present invention can improve the water-retaining property of soil to crop and environment.
Detailed description of the invention
A kind of water-retaining type oils and fats coated slow-release Oryza sativa L. fertilizer, is made up of the raw material of following weight portion (kilogram):
Waste grease 20, iodine 0.05, Talcum 10, fish scale 100, carbamide 80, Caulis et Folium Oryzae 20, rice chaff 19, potassium fulvate 0.4, egg
Propylhomoserin zinc 0.3, auxin 0.1, yeast waste liquor 5, sodium alginate 2,0.4mol/L sodium hydroxide solution 800, glutaraldehyde 5, dense ammonia
Water is appropriate, microbial germ powder 0.4, bentonite 18.
The preparation method of described oils and fats coated slow release fertilizer, comprises the following steps:
(1) adding iodine in waste grease, after being heated to 180 DEG C under nitrogen protection, isothermal reaction 2.5 hours, continues to be passed through
Nitrogen is made protection standing and is cooled to 22 DEG C, obtains conjugation modified grease；
(2) by Talcum grinds, make particle diameter reach 0.01mm, obtain Pulvis Talci；
(3) fish scale is washed surface impurity, dry, add after 0.4mol/L sodium hydroxide solution soaks 30 minutes and take out, use
Distilled water wash 2 times, dries, pulverizes, and crosses 100 mesh sieves；
(4) step (3) gained material is added the distilled water of 20 times, adds strong aqua ammonia regulation pH to 7.6, ultrasonic disperse 10 minutes, add
Entering carbamide, stir 2 hours after dissolving at 30 DEG C, add glutaraldehyde, continue stirring 2 hours, then carry out sucking filtration, gained sinks
Form sediment and be dried 48 hours at 45 DEG C；
(5) Caulis et Folium Oryzae, rice chaff being pulverized, regulation to the water content that adds water reaches 40%, adds microbial germ powder, the vexed fermentation of heap 25 days, phase
Between turning in 5 days once, the raw material mixing granulation that gained material is unused with step (4) gained material and above-mentioned technique, at 40 DEG C
Under be dried to constant weight, obtain fertilizer kernel；
(6) conjugation modified grease is mixed with Pulvis Talci, be sprayed on fertilizer core surface, be dried, to obtain final product.
The fertilizer of the present invention is used for rice cultivation experiment, selects 5 mu of planting bases, use the fertilizer of the present invention, as
Experimental group, 5 mu of base planting requirements routinely of matched group execute common fertilizer, and other condition is identical, it is demonstrated experimentally that experimental group kind
The Oryza sativa L. planted, in the case of reaching equal production volume, greatly reduces Fertilizer application amount, and raw material is easy to get simultaneously, and cost of material compares
Low, save labour, protect environment, on year-on-year basis economic raising 16.2%.
