Description

A kind of biomass organic fertilizer improveing soil agreegate

Technical field

The present invention relates to organic fertilizer technical field, particularly relate to a kind of biomass organic fertilizer improveing soil agreegate.

Background technology

Along with the specialization of China's agricultural production, industrialization, the development of scale; agricultural is constantly upgraded for the requirement of fertilizer, soil fertility; and a large amount of uses of tradition inorganic fertilizer cause soil physico-chemical property to deteriorate; the yield of agricultural product, quality and resistance decline, and constrain the sustainable development of agricultural planting.Manure use is selected to improve planting conditions for problem above many agricultural plantings family, but the committed step in fertilizer preparation process is the decomposition to the cellulose substances that difficulty is decomposed, in the structure of straw, cellulose is the important composition composition of stalk cell wall, play support and the major function of fixing plant, it is difficult to, by biological decomposition, hinder release and the mineralising of cellular content.

For this, using enzyme that Plant fiber carries out degraded is a kind of preferably method, but free enzyme is not sufficiently stable under the conditions of high temperature, strong acid, highly basic, high ion concentration etc., easily inactivates and reduce its catalytic capability, cause the considerable restraint in application.

In soil, aggregate amounts have impact on many physicochemical characters such as soil fertility, permeability, growth to crop has large effect, for this, the present inventor provides the method for the immobilized enzyme of a kind of biomass carbon, to improve the stability of enzyme and anti-inhibition, and the present situation of bigger defect is had for the most a large amount of soil physico-chemical properties, it is provided that and a kind of biomass organic fertilizer improveing soil agreegate, in order to promote the development of agricultural planting industry.

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 biomass organic fertilizer improveing soil agreegate.

The present invention is achieved by the following technical solutions:

A kind of biomass organic fertilizer improveing soil agreegate, is prepared by the raw materials in: flue-cured tobacco powder 34-36, bentonite 6-7, poly-aspartate 3-4, Diammonium phosphate (DAP) 5-6, wheat gluten flour 9-10, sulphuric acid Asia nickel 2-3, ferric citrate 3-5, agricultural crop straw 58-64, waterweed 75-77, cellulase preparation 2-3, protease preparation 4-5, tamarind fruit 7-9, water are appropriate.

Specifically comprising the following steps that of the preparation method of described biomass organic fertilizer

(1) filter after tamarind fruit squeezing juice, filtrate and sulphuric acid Asia nickel, ferric citrate are mixed and heated to 74-76 DEG C, stir 20 minutes post-dryings, obtain powder standby；

(2) waterweed drying is placed in sealing high temperature furnace, it is warming up to 450 DEG C with the speed of 5-7 DEG C/minute, continues heating and thermal insulation 110-120 minute after reaching final temperature, take out after cooling, by gained charcoal grinding and sieving, take particle diameter standby at the granule of 0.15-0.25mm；

(3) charcoal and water are soaked 18-24 hour after 1:9 mixes in mass ratio, continue after centrifugal segregation supernatant to repeat to soak, to supernatant colourless after by gained charcoal dry for standby at 47-50 DEG C；

(4) by the potassium permanganate solution of step 3 gained charcoal with 0.2mol/L after 1:12 mixes in mass ratio, use frequency is 30-40kHz, power is that ultrasonic echography 60-80 minute of 15W is with mixing, heating be evaporated after in putting into high temperature furnace at 500-550 DEG C Non-oxygen pyrolytic 30-40 minute, the biological carbon materials having obtained Mn oxide immobilized, standby；

(5) in step 4 gained biological carbon materials, 5-6 times of quality water is added, add cellulase preparation and protease preparation, regulation liquid PH is 5.0-5.5, impregnate 7 hours after being slowly stirred at a room temperature 15-20 minute, filter and dry at 48-52 DEG C, obtain the charcoal composite that exogenous enzyme is fixing；

(6) by step 1 gained tamarind marc and agricultural crop straw, flue-cured tobacco powder, the wheat gluten flour laggard row compost fermentation of mixing, after 20 days, compost temperature reduces, add bentonite, poly-aspartate and step 5 gained charcoal composite, continue fermentation 12-15 days；

(7) pulverize after step 6 gained fermentation material being dried under 45-50 DEG C of low temperature, and mix with Diammonium phosphate (DAP), step 1 gained powder and other leftover materials and be placed in comminutor granulation, obtain biomass fertilizers of the present invention.

The invention have the advantage that

The by-product attachments such as inorganic salt that waterweed gained charcoal surface after pyrolysis can produce during being pyrolyzed, vinegar liquid, tar, therefore use and mix the centrifugal eluting of immersion with water to remove impurity, both improve the absorption property of charcoal, the secondary pollution that impurity causes after entering soil can have been prevented again.

Mn oxide is immobilized on charcoal being greatly improved the adsorption effect of its heavy metal, strengthens the fertiliser granulates restraining forces to heavy metal pollution of soil, improve Soil Safety.

Cellulase and proteinase synergy effect is used to carry out degradable fermented to compost, the degraded of stalk cellulose is promoted by cellulase, destroy the framing structure of stalk cell wall, again by the crude protein on proteases for decomposing stalk cell wall, cell wall is formed passage and improves nitrogen content, final decomposing and fermenting material completely, significantly improves the nutrient content of fertiliser granulates.

The biomass fertilizer of the present invention passes through charcoal and the interpolation of multiple organic matter, the content of the big reunion of water stability in soil can be improved at short notice and strengthen the sedimentation of soil, the use of microbial inoculum enriches again probiotics group in soil, improvement soil microenvironment, the plantation performance of soil can be improved without soil being carried out the transformation of engineering aspect, improving the surcharge of soil.
