Description

A kind of late rice dedicated fertilizer and preparation method thereof

Technical field

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

Background technology

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

Current Rice Cropping fertilizer type used is a lot, NPK composite fertilizers that can buy on loose many employings market for paddy rice early wherein, and mainly by N, P, K tri-, large inorganic elements forms for it, can meet at short notice the growth needs of paddy rice.But life-time service can make soil aggregate be destroyed, easily cause soil compaction, soil property hardening, thereby affect paddy growth, not obvious to paddy growth promoter action.Though simple fertilizer is rich in organic matter simultaneously, nutrient discharges slowly, and rice absorbing is slow, fertilizer efficiency is low, between various available nutrient, does not reach active balance.

Paddy rice prevention and elimination of disease and pests is at present mainly formulated with chemical synthetic pesticide and poisonous chemical principle medicine, be manured into soil or agriculture 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 agriculture paddy rice are polluted, and agricultural product quality declines, and pesticide residue exceed standard and seriously have a strong impact on people's physical and mental health and China paddy rice in the competitive power of world market.

Therefore, developing a kind of brand-new late 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 there is no resistance, various pests is all had to repelling and killing efficacy, and to people and animals and surrounding environment without any pollution.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of late rice dedicated fertilizer and preparation method thereof.Fertilizer of the present invention combines fertilizer, inorganic fertilizer, middle trace element and plant insecticide composition, formula rationally, nutrition more comprehensively, equilibrium, result of use is good, thereby has improved the yield and quality of paddy rice.

The technical solution used in the present invention is as follows:

A late rice dedicated fertilizer, is characterized in that, by the raw material of following weight part, is made:

Dregs of beans 10-20, coated carbamide 8-10, coating primary ammonium phosphate 24-26, potassium sulfate 8-10, plant ash 20-30, ferrous sulfate 1-2, zinc sulfate 1-2, borax 0.1-0.3, gelatin 10-12, xanthohumic acid 5-7, willow sawdust powder 3-4, Folium seu Cortex Nerii powder 3-4, bagasse 10-15, calcium carbonate 10-15, Chinese medicine slag 18-22, carboxymethyl cellulose 3-4,30% sulfuric acid 15-20, lime 5-10, chicken feather 10-15, Oleum Gossypii semen 2-3.

The preparation method of late rice dedicated fertilizer of the present invention, comprises the following steps:

(1) first chicken feather is added in 30% sulfuric acid, at 100-110 ℃, be hydrolyzed 1-2 hour, generate amino acid, then add lime and be neutralized to Ph value 6.0-6.8, add again carboxymethyl cellulose, finally add ferrous sulfate, zinc sulfate, borax to dissolve, at 90-105 ℃ of reaction 5-6 hour, generate micro-, the middle fertilizer liquid of chelating amino acids;

(2) by calcium carbonate after 400-500 ℃ of sintering 6-8 hour, add the Oleum Gossypii semen of about 1-2% to grind to form nanometer powder, then mix with plant ash;

(3) adopt During High-Temperature Composting fermentation fertilizer, get dregs of beans, bagasse, Chinese medicine slag and add appropriate subtilis, mix rear 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 obtain fermentation finished thoroughly1, stand-by;

(4) by coated carbamide, coating primary ammonium phosphate, potassium sulfate co-grinding, then the fertilizer fermenting with gelatin, xanthohumic acid, step (3) mixes, and pulverizes, crosses 100-200 mesh sieve;

(5) after biotic pesticide willow sawdust powder and Folium seu Cortex Nerii powder are mixed, more fully mix with the material of step (2), (4);

(6) micro-, the middle fertilizer liquid of chelating amino acids step (1) being made sprays in the mixture of step (5), fully mixes rear input granulator granulation thoroughly, finally sprays Oleum Gossypii semen and carries out coating, obtains late rice dedicated fertilizer.

Fertilizer of the present invention is exclusively used in late 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 then centering, trace element carry out chelating, and carboxymethyl cellulose has increased its chelate structure, in being conducive to, trace element effectively utilizes, in having reduced, the invalid release of trace element;

(2) calcium carbonate composition, after scaling loss, grinds with Oleum Gossypii semen, has increased adsorption structure, and anti-caking, increases its dispersiveness simultaneously;

(3) in formula, increase inorganic slowly-releasing composition if gelatin and soil improvement composition are as bagasse, xanthohumic acid, be conducive to effectively slowly discharging, fully being absorbed by paddy rice of fertilizer efficiency;

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

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