Abstract

The invention discloses a special controllable slow-release organic fertilizer for rice. The organic fertilizer is prepared from raw materials in parts by weight as follows: 5-6 parts of ocher, 55-65 parts of cow dung, 3-4 parts of calamine, 2-3 parts of urea, 3-4 parts of zinc sulfate, 15-25 parts of kaolin, 6-8 parts of hydrilla varticillata powder, 3-4 parts of spodumene powder, 4-5 parts of ammonium dihydrogen phosphate, 2-3 parts of potassium persulfate, 10-12 parts of straw stalk, 5-6 parts of soybean oil residues, 3-4 parts of illite powder, 8-10 parts of sawdust, 20-30 parts of a soil conditioner, 4-5 parts of an EM agent and a proper amount of water. According to the fertilizer, the cow dung is taken as a main raw material, and slow release of the fertilizer is controlled accurately through strict control on particle sizes of fertilizer granules, so that the requirement of the rice for the fertilizer in different growth periods is met; meanwhile, multiple highly-absorbent raw materials in the raw materials are used, so that pesticide residues and heavy metal pollution in soil can be eliminated, and the foundation is laid for the green and ecological agriculture.

Description

Controllable sustained-release organic fertilizer that a kind of paddy rice is special and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, controllable sustained-release organic fertilizer that particularly a kind of paddy rice is special and preparation method thereof.

Background technology

China is large agricultural country, agricultural is the basis of national economy, and wherein plant husbandry accounts for again over half, and the quality of fertilizer directly affects the output of plant husbandry, is the important factor of increasing crop yield.But peasant, in order to pursue crop yield, uses chemical fertilizer blindly, make soil organic matter content have downtrending, buffering power of soil weaken, anti-disaster ability fails, utilization rate of fertilizer is low, soil fertility reduce.Along with chemical fertilizer excessively uses the appearance of the environmental problem caused, the popularization of pollution-less agriculture, and new-type fertilizer research field is constantly widened, development is efficient, green, continuable novel organic fertilizer material is imperative.For this reason, the invention provides a kind of environmental protection organic fertilizer of high-quality.

Summary of the invention

The present invention compensate for the deficiencies in the prior art, controllable sustained-release organic fertilizer providing a kind of paddy rice special and preparation method thereof.

Technical scheme of the present invention is as follows:

Described soil conditioner is made up of the raw material of following weight part: Agaricus blazei slag 8-12, Beer Sludge 40-60, urea 10-15, sawdust 20-30, EDDHA chelated iron 5-6, copper amino acid chelate 5-6, amino acid chelated magnesium 5-6, calcium amino acid chelate 5-6, chelating amino acids boron 5-6, chelating amino acids manganese 5-6, zinc-amino acid chelate 5-6, polyacrylamide 2-3, potassium felspar sand fine powder 1-2, EM microbial inoculum 4-5; Its preparation method EDDHA chelated iron, copper amino acid chelate, amino acid chelated magnesium, calcium amino acid chelate, chelating amino acids boron, chelating amino acids manganese, zinc-amino acid chelate to be mixed and to grind to form fine powder for subsequent use; Again Beer Sludge and sawdust are fully mixed, add EM microbial inoculum, Agaricus blazei slag, and regulate moisture to be compost water retaining capacity 60%-70%, pile up to get up to carry out Aerobic thermophilic compost, within 6-8 days, carry out once up and down, inside and outside turning, so carry out 4-5 time, high temperature 50-60 DEG C of lasting 25-35 days completes fermentation, the Beer Sludge compost fermented is shone dry doubling and pulverizes; Will above gained fine powder and compost dry powder blend even, by urea spray granulating, mixed powder is made spheroidal particle again, at the non-complete drying of particle, also forming coating with polyacrylamide and the mixing of potassium felspar sand fine powder being sprayed on particle exterior surface under the condition of a little viscosity, finally gained coated granule oven drying at low temperature being cooled.

The concrete steps of the preparation of described fertilizer are as follows:

(1) by deodorizing after cow dung drying, pulverize after mixing with rice straw, then mix with EM microbial inoculum and Oil Residue, wood chip and be placed in the fermentation that fermentation vat carries out 20-30 days, period, every turning in 5-7 days once leavening temperature remained on 55-65 DEG C;

(2) mixed with hydrilla verticillata powder, triphane powder, kaolin by tunning, air-dry rear pulverizing granulation, gets particle diameter 4-6mm particle for subsequent use, granulation again after underproof particle pulverizing;

(3) fine powder is ground to form and granulation by after ochre, Calamine, zinc sulfate, primary ammonium phosphate, Potassium Persulphate, Erie's stone flour mixing;

(4) by step 2 and the mixing of step 3 gained particle, then be coated on after Urea melting outside particle, then mix with leftover materials, after cooling, be packaged into bag.

Beneficial effect of the present invention:

Fertilizer of the present invention adopts cow dung as main raw material, by the fertiliser granulates size strictly controlled, with accurately control fertilizer slowly-releasing, thus meet the different times of paddy rice in growth to the demand of fertile part, simultaneously in raw material, the use of multiple strong adsorptivity raw material can eliminate pesticide residue in soil and heavy metal contamination, for green ecological agricultural provides the foundation.

Containing abundant nutritive substance in the soil conditioner added, particle is little, hole is many, obviously can increase the content of the soil organism, trace element, increases water-absorbent and the water-retentivity of soil, effectively improves soil physical and chemical property.
