Abstract

The invention provides a special fertilizer for single cropping rice. The special fertilizer is prepared by the following raw materials by weight: 10-20 parts of cottonseed meal, 8-10 parts of coated nitrogen-phosphorus-potassium mixed fertilizer, 25-40 parts of calcium superphosphate, 8-10 parts of coated potassium chloride, 20-30 parts of plant ash, 1-2 parts of ferrous sulfate, 1-2 parts of zinc sulfate, 0.1-0.3 parts of borax, 10-12 parts of medical stone, 5-7 parts of peat, 3-4 parts of celastrus orbiculatus powder, 3-4 parts of oleander powder, 10-15 parts of bagasse, 10-15 parts of dolomite, 18-22 parts of chicken manure, 3-4 parts of carboxymethylcellulose, 15-20 parts of 30% of sulfuric acid, 5-10 parts of lime, 10-15 parts of chicken feather and 4-6 parts of propanediol sebacate polyester. A preparation method of the single cropping rice comprises the steps as follows: carrying out acidolysis on hairs to obtain amino acid; generating an amino acid chelated micro or medium fertilizer solution; sintering the dolomite to prepare a fertilizer carrier; fermenting an organic fertilizer; mixing the nitrogen-phosphorus-potassium mixed fertilizer and the carrier with the organic fertilizer and a plant insecticide; spraying the amino acid chelated micro or medium fertilizer solution; granulating; and finally coating with the propanediol sebacate polyester. According to the special fertilizer, the utilization rate of fertilizer efficiency can be remarkably increased, the slow release effect is achieved, the fertilizing amount is reduced, and the pesticide residues are reduced, so that the yield and the quality of the rice are improved.

Description

A kind of single cropping rice dedicated fertilizer and preparation method thereof

Technical field

The present invention relates to the agricultural fertilizer field, be specifically related to single cropping rice dedicated fertilizer and preparation method thereof.

Background technology

China is a large agricultural country, and chemical fertilizer and agricultural chemicals are being brought into play crucial effect in agriculture prodn, the raising of Along with people's standard of living and health perception, and people pay much attention to the security of agricultural-food, and demand nuisanceless, green food is increased year by year.

The used fertilizer type of current paddy rice plantation is a lot, and wherein paddy rice-dedicated fertilizer adopts the NPK composite fertilizer that can buy on the market mostly, and it mainly is made up of N, P, K three big inorganic elementss, can satisfy the growth needs of paddy rice at short notice.But life-time service can make soil aggregate destroyed, and is prone to cause soil compaction, soil property hardening, thereby influences paddy growth, and is not obvious to the paddy growth promoter action.Though simple fertilizer is rich in organic matter simultaneously, nutrient discharges slowly, and paddy rice absorbs slowly, fertilizer efficiency is low, does not reach active balance between the various available nutrients.

Paddy rice prevention and elimination of disease and pests at present mainly is formulated with chemical synthetic pesticide and poisonous chemical principle medicine; Be manured into soil or agricultural paddy rice on, life-time service year in year out, a large amount of agricultural chemicals and chemical fertilizer; Cause insect to produce resistance; Water source soil and agricultural paddy rice are polluted, and agricultural product quality descends, the pesticide residue physical and mental health that seriously has a strong impact on people and China paddy rice competitive power in the world market that exceeds standard.

Therefore; Developing a kind of brand-new single cropping rice dedicated fertilizer material is the task of top priority, and fertilizer energy collecting of the present invention is that paddy rice supplies nutrients, desinsection, sterilization, promotion grow in one, and do not have resistance; Various pests is all had repelling and killing efficacy, and people and animals and surrounding environment are not had any pollution.

Summary of the invention

In order to overcome the deficiency of prior art, the invention provides a kind of single cropping rice dedicated fertilizer and preparation method thereof.Fertilizer of the present invention combines fertilizer, inorganic fertilizer, middle trace element and plant insecticide composition, and prescription is reasonable, and nutrition is more comprehensive, balanced, and result of use is good, thereby has improved the yield and quality of paddy rice.

The technical scheme that the present invention adopts is following:

A kind of single cropping rice dedicated fertilizer is characterized in that, is processed by the raw material of following weight part:

Cotton cake dregs 10-20, coating nitrogen phosphorus potassium NPK 8-10, superphosphate of lime 25-40, coating Repone K 8-10, plant ash 20-30, ferrous sulfate 1-2, zinc sulfate 1-2, borax 0.1-0.3, medical stone 10-12, peat 5-7, Stem of Oriental Bittersweet powder 3-4, Sweet-scented Oleander Leaf powder 3-4, bagasse 10-15; Rhombspar 10-15, chicken manure 18-22; CMC 99.5 3-4,30% sulfuric acid 15-20, an amount of, the chicken feather 10-15 of lime, sebacic acid Ucar 35 polyester 1-2.

The preparation method of single cropping rice dedicated fertilizer of the present invention may further comprise the steps:

(1) earlier chicken feather is added in 30% sulfuric acid; 100-110 ℃ following hydrolysis 1-2 hour, generate amino acid, add lime then and be neutralized to Ph value 6.0-6.8; Add CMC 99.5 again; Add ferrous sulfate, zinc sulfate, borax dissolving at last,, generate little, the middle fertilizer liquid of chelating amino acids 90-105 ℃ of reaction 5-6 hour;

(2) with rhombspar after 400-500 ℃ of sintering 6-8 hour, the sebacic acid Ucar 35 polyester that adds about 1-2% grinds to form nanometer powder, mixes with plant ash again;

(3) adopt During High-Temperature Composting fermentation fertilizer; Get cotton cake dregs, bagasse, chicken manure and add an amount of subtilis, mix the back heap fermentation, turning in 5-10 days once; Leavening temperature 60-65 ℃; Fermentation time is 30-40 days, in heap, is covered with the fertilizer that a large amount of white hyphas promptly obtain fermentation finished thoroughly1, and is for use;

(4) coating nitrogen phosphorus potassium NPK, superphosphate of lime, coating Repone K are mixed pulverizing, mix with the fertilizer that medical stone, peat, step (3) ferment again, and pulverize, cross the 100-200 mesh sieve;

(5) with biotic pesticide Stem of Oriental Bittersweet powder and Sweet-scented Oleander Leaf powder evenly after, again with the material thorough mixing of step (2), (4);

(6) little, the middle fertilizer liquid of chelating amino acids that step (1) is made sprays in the mixture of step (5), fully mixes the back thoroughly and drops into the tablets press granulation, sprays sebacic acid Ucar 35 polyester at last and carries out coating, promptly gets the single cropping rice dedicated fertilizer.

Fertilizer of the present invention is exclusively used in the base fertilizer of paddy rice, every mu of fertilising 80-100kg.

Beneficial effect of the present invention:

(1) the present invention adopts acid hydrolysis feather etc. to generate amino acid, and centering, trace element carry out chelating then, and CMC 99.5 has increased its chelate structure, in helping, trace element effectively utilizes, in having reduced, the invalid release of trace element;

(2) the rhombspar composition adds sebacic acid Ucar 35 polyester and grinds through after the scaling loss, has increased adsorption structure, and anti-simultaneously caking increases its dispersiveness;

(3) increased inorganic slowly-releasing composition such as medical stone and soil improvement composition such as bagasse, peat in the prescription, effectively slowly release, the paddy rice that help fertilizer efficiency fully absorb;

(4) adding of plant insecticide composition can effectively reduce the soil disease and pest, and does not produce agricultural residual phenomenon, does not develop immunity to drugs.

In a word, fertilizer of the present invention can obviously improve the fertilizer efficiency utilization ratio.Can single-dose application, slowly effectively discharge, can reduce Effects of Fertilization Frequency, reduce dose, reduce production costs, it is residual to reduce farming.Improve the yield and quality of paddy rice.
