Abstract

The invention discloses long-acting slow release organic fertilizer which is prepared by raw materials in parts by weight as follows: 4-5 parts of activated carbon, 10-15 parts of edible starch pulp, 5-6 parts of zeolite powder, 7-8 parts of medical stone powder, 6-8 parts of gelidium amansii, 4-5 parts of potassium sulfate, 35-45 parts of animal waste, 12-18 parts of spirulina powder, 1-2 parts of talcum powder, 3-4 parts of ground phosphate rock, 5-6 parts of ammonium sulfate, 2-3 parts of urea, 3-4 parts of sodium sulfate, 5-6 parts of biochemical fulvic acid, 20-30 parts of a soil conditioner and appropriate water. The long-acting slow release organic fertilizer adopts a double-envelope structure comprising a molten urea layer and the talcum powder, by means of slow release of the urea and high adsorbability of the talcum powder, release of fertilizer nutrients can be controlled effectively, waste caused by the fact that a large quantity of fertilizer components cannot be effectively absorbed by plants is prevented, meanwhile, the added raw materials such as the gelidium amansii, the spirulina powder and the like contain large quantities of trace elements such as iron, calcium, magnesium and the like required by the plants, and healthy growth of the plants is facilitated.

Description

A kind of long-acting slow-release organic fertilizer and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly a kind of long-acting slow-release organic fertilizer 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, provides a kind of long-acting slow-release organic fertilizer and preparation method thereof.

Technical scheme of the present invention is as follows:

Fertilizer of the present invention is made up of the raw material of following weight part: gac 4-5, food starch slag 10-15, zeolite powder 5-6, medical stone powder 7-8, gelidium 6-8, potassium sulfate 4-5, animal excrement 35-45, spirulina powder 12-18, talcum powder 1-2, ground phosphate rock 3-4, ammonium sulfate 5-6, urea 2-3, sodium sulfate 3-4, biochemical fulvic acid 5-6, soil conditioner 20-30, water are appropriate;

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 dry for animal excrement deodorizing, then food starch slag, gelidium, spirulina powder mixing are added suitable quantity of water boiling sterilizing in 40-60 minute, mix with animal excrement, biochemical fulvic acid and be placed on normal temperature aerobic fermentation 20-30 days in fermentation vat;

(2) by medical stone powder, gac, potassium sulfate, ground phosphate rock, ammonium sulfate, sodium sulfate, zeolite powder mixed grinding 30-60 minute, then with the granulation of step 1 gained fermentation materials extrusion;

(3) will be coated on after Urea melting outside step 2 gained particle, then talcum powder is sprayed on outside fusing urea layer;

(4) step 3 gained multilayer coating structure particle mixed post-drying with leftover materials and cool, being packaged into bag.

Beneficial effect of the present invention:

Organic fertilizer of the present invention adopts fusing urea layer and the double-deck capsule structure of talcum powder, utilize the slow releasing of urea and talcous strong adsorptivity, effectively can control the release of fertilizer nutrient, prevent a large amount of fertile part from can not effectively be absorbed by plant and waste, the raw materials such as the gelidium simultaneously added, spirulina powder contain the required trace element of the plants such as a large amount of iron, calcium, magnesium, are conducive to the healthy growth of plant.

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.
