Description
Technical field
The present invention relates to a kind of method of biological organic fertilizer, be specifically related to a kind of method of utilizing the agent of xylogen organic granular to produce biological organic fertilizer.
Background technology
Microbial fertilizer is the specific fertilizer goods that a class contains living microorganism, it is a kind of new-type fertilizer that meets country's agricultural, high-tech and the requirement of environmental protection three industries, being the product of the tool representative of complying with world's fertilizer developing direction and satisfying that agriculture new system sets up, is an importance that realizes China's agricultural sustainable development.China has progressively set up the viewpoint of Chinese food safety appraisement system, not only production environment has been proposed requirement, and strict regulation have also been formulated in the use of fertilizer.Built some pollution-free foods production base in the whole nation at present, this development also provides fabulous opportunity to develop for Development and Production high-effective microorganism fertilizer.
Microbial fertilizer is described as the star of hope of 21 century by people, that vital movement with microorganism causes crop to obtain a kind of goods of specific fertilizer effect, it has enhancement soil fertility, improve Crop nutrient ability, strengthen the disease-resistant and drought-resistant ability of plant, and can produce several physiological active substances, can stimulate the effects such as plant growth.Not only can increasing both production and income after application, reduce or reduce the usage quantity of chemical fertilizer, and can improve quality of agricultural product.Biological organic fertilizer product as one of biological fertilizer products is subject to people's common concern due to its dual function with bio-feritlizer and organic granular agent material.
The biological organic fertilizer product of selling on China market at present is mainly take powder-like product as main, because powder-like product easily floats down on the wind, use inconvenient and limited the spread of product, so powder-like product has outside certain consumption at Southern Fruit Trees and vegetables as base fertilizer, in the north due to large-scale agriculture, be all generally the machine fertilising, powder-like product is difficult to machine sowing, has therefore limited the popularization of biological organic fertilizer product.For energy spread bio-organic fertilizer, better be the agriculture production service, be the trend of a development with the biological organic fertilizer round shaped grain.But the biological organic fertilizer round shaped grain has several problems to overcome on producing:
The one, organic raw material: the biological organic fertilizer product of some round shaped grain type on present market, but be to carry out granulation with humic acid (humic acid) as organic carrier substantially, other organic raw material is as holding poultry manure, straws etc. are many due to wood fibre, light specific gravity, viscosity and fineness are difficult to balling-up not, they are mainly take the columnar product of extruder grain as main, but column still can not machine sowing.In addition, humic acid belongs to mineral substance, resource-constrained, exploitation can destroy ecology in a large number, and executes very difficult dissolving in soil, and organic matter wherein and humic acids are difficult to by crop utilization, affect fertilizer efficiency, the price of humic acid also goes up year by year simultaneously, and the production cost of product is also improving year by year.Feces of livestock and poultry is slow due to its fermentation maturity, atmospheric pollution heavy, occupied ground is large, time-consuming, be difficult to produce in batches on a large scale, after being applied to soil, not exclusively will cause the burning seedling if become thoroughly decomposed, and owing to holding harmful germs such as containing a large amount of intestinal bacteria and roundworm egg in poultry manure, long-term application is held the increase that the organic granular agent meeting of poultry manure production brings soil disease.
The 2nd, the granulation oven dry impact on microorganism live bacteria: with the technique of microbial organic fertilizer pelleting mainly with disc granulation or drum granulating; all to dry through dram after granulation; high temperature can kill the microorganism live bacteria of product, so restricted the granulating of biological organic fertilizer.
The 3rd, the indissoluble solution: utilizing humic acid to also have a problem as organic carrier production round shaped grain biological organic fertilizer is exactly to be difficult to dissolving, because humic acid belongs to mineral substance, very large through fertiliser granulates intensity after the granulation oven dry, execute in soil and to be difficult to suction and to dissolve, and the organic matter that wherein contains and humic acids are difficult to by soil and crop utilization, will affect the product effect like this, the marketing of product is brought very large impact.
Due to above reason, the biological organic fertilizer round shaped grainization will be had influence on quality and the effect of product, therefore caused the product promotion difficulty.
7761 of the at present total papermaking of China and paper product enterprises, 6,500 ten thousand tons of annual national paper outputs, and wastewater discharge remains on 3,100,000,000 tons of left and right, the seriously polluted development that is restricting papermaking enterprise of water, compulsory execution due to the national industrial policies of the pollution treatment cost of great number and low-carbon economy and energy-saving and emission-reduction, for papermaking enterprise, key is that whether economic strength is administered pollution.

Further, the particle diameter of described xylogen organic granular agent is controlled at 1.0-4.0mm.This particle diameter can make the infiltration of bacterium liquid evenly, and the specific surface area of appropriate particle size also makes the living bacteria count of postvaccinal granular organic fertilizer reach quality standards.
In a preferred embodiment, described step (2) can be added one or more of following material in the spray granulating operation: nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, trace element fertilizer.If the composite microbiological fertilizer of production Different Nutrients content can add nitrogen phosphorus potassium inorganic nutrients raw material in the spray granulating process, to improve total nutrient (N+P in product
2O
5+ K
2O) content, its concrete formula obtains according to the nutrient content of different material and the technical indicator cubage of product.Wherein the main raw material of N has: urea, ammonium sulfate; P
2O
5Main raw material have: monoammonium phosphate, diammonium phosphate, calcium superphosphate and calcium magnesium phosphorus; K
2The main raw material of O has: Repone K and vitriolate of tartar also can add middle trace element: magnesium sal epsom; Calcium nitrocalcite; The manganese manganous sulfate; Zinc zinc sulfate; The boron borax; Copper copper sulfate, iron is with ferrous sulfate etc.
Further, described step (2) can be added organic matter material in the spray granulating operation.As shown in table 1, the organic content of the xylogen organic granular agent after granulation reaches the requirement of " biological organic fertilizer " agriculture standard (NY884-2004).If want to produce the more composite microbiological fertilizer of high organic content, can add organic matter material in the spray granulating process, to improve content organic in product, concrete formula obtains according to the content of organic matter material and the technical indicator cubage of product, high-quality organic matter material commonly used has: the peat composed of rotten mosses, humic acids etc., also can be in cost consideration, select other organic matter materials.
It is air-dry or dry that above-mentioned steps (3) is mentioned, that the composite microbiological fertilizer that will be sprayed with bacterium liquid is slightly done just to dry through the cooling cylinder that cold wind is arranged and can be entered feed bin, as finished product packing, if there is no cooling apparatus, less than 6% organic granular agent, evenly spraying just can become finished product after the inoculation of bacterium liquid and directly enter the feed bin packing and put in storage for moisture.
Because xylogen organic granular agent moisture content is very low, all in 10%, the bacterium liquid that sprays 0.5-1.5% can not impact moisture, the intensity of biological organic fertilizer particle, and can not surpass granular bioorganic fertilizer moisture less than 15% requirement.Above stirrer can be disk or rotary drum cylinder, is that continuous uniform flows forward but require material wherein.Adopt the compound method of liquid composite microbial microbial inoculum of the present invention and organic granular agent, according to physico-chemical properties such as the water content of xylogen organic granular agent and granularities, rationally control the adding proportion of liquid bacterial agent, not only make the requirement that meets " biological organic fertilizer " agriculture standard (NY 884-2004) in the biological organic fertilizer that makes, and simplified the step of oven dry, directly put in storage or only need cold wind to dry slightly and can put in storage, the time that cold wind dries is according to moisture, the atmospheric moisture of material were grasped flexibly at that time.
The present invention is exactly microbe inoculation microbial inoculum on the basis of the organic granular agent that utilizes spray granulating to produce, biological organic fertilizer is processed in the organic granular agent, increases the technology content of product, improve the effect of product, due to this organic granular agent organic matter 〉=30%, N+P
2O
5+ K
2O 〉=1.5%, and this organic granular agent smooth surface, uniform particles, water soluble, the microbiobacterial agent of inoculation ratio of the present invention on this particle, make that in product, microorganism live bacteria quantity reaches requirement, quality product just meets the requirement of " biological organic fertilizer " agriculture standard (NY 884-2004) fully, can effectively solve the technical problem that biological organic fertilizer faces at present, make up deficiency of the prior art, make simultaneously xylogen organic liquid waste or the lignin liquor that papermaking enterprise produces reach disposal of resources and effectively utilize.
From having disclosed data now: the material that has is also reported the production method of granulated fertilizer dressing bacteria agent, but see it is at inorganic composite fertilizer (or composite fertilizer) surface coatings microbial inoculum from example, because compound manure belongs to the chemical fertilizer of high-content, in the combination of surface coatings microbial inoculum due to inorganic nutrients and microorganism, a large amount of salt ions infiltrates thalline can cause the microorganism mortality, can't play the purpose of effective inoculation, science not at chemical fertilizer or inorganic composite fertilizer surface coatings microbial inoculum, irrational.the simple declaration that is reported in organic granular agent surface coatings microbial inoculum is also arranged, but composition and the content of organic granular agent are not described, because the microorganism that contains in microbiobacterial agent is living microorganism, different organic raw material has a great impact its vital movement, composition and the content of concrete organic granular agent are not described, also can't realize the possibility of dressing bacterial classification success, so the data granulated fertilizer dressing bacterial classification of above report does not have feasibility, and these data do not illustrate the technological standard that obtains product after the dressing microbial inoculum yet, can't obtain the license of country and realize producing and promoting.
Compared with prior art, the present invention has following beneficial effect:
1, broken the traditional mode of producing biological organic fertilizer with feces of livestock and poultry or the peat composed of rotten mosses, humic acid, for the production of biological organic fertilizer provides a kind of new starting material.The present invention directly changes into xylogen organic granular agent product with the xylogen black liquor, and having eliminated exhaust emission has good economic benefit because obtaining product again.Administer thoroughly, blowdown is zero, ecotope has been protected in the fully reuse and not effluxing of effluent resource, engineering non-wastewater discharge, the water of condensation that is produced by secondary steam.
2, solved the technical barrier that utilizes spray granulating to produce bio-feritlizer: spray granulating uniform particles, smooth surface, granule strength are high, commodity is good, be easy to dissolve and be subject to user's welcome, but can't carry out the production of microorganism particle fertilizer due to high temperature (over the 1000 ℃) oven dry of spray granulating technique, spray can be fallen granulation and access the way that bacterial classification separately carries out by this Technology, having realized that composite microbiological fertilizer sprays production and the application of falling particle.
3, the present invention looks for another way, break the normal procedure, the production technique of spray granulating is introduced the Production Flow Chart of biological organic fertilizer, the production method of whitewashing granular bioorganic fertilizer is divided into whitewashing organic granular agent granulation and two steps of organic granular agent parcel microbial inoculum, the activity of having possessed simultaneously certain biological organic fertilizer, the biological organic fertilizer Realization of Product by powdery to granular breakthrough, for the large-scale popularization of biological organic fertilizer is laid a good foundation.
4, for some papermaking enterprises with certain strength, make the organic granular agent with the xylogen waste liquid that stalk and timber production paper pulp produce by spray granulating after concentrated, turn waste into wealth, both solved the pollution problem of waste water, produced again organic granular agent product.But because the papermaking enterprise waste liquid amount is large, xylogen organic granular agent production capacity is very high, and this organic granular agent price is with low content of technology, and the product effect is limited, and added value is not high, affect the sales volume of product, cause a large amount of overstocking, cause white elephant to enterprise.The method according to this invention, can directly the organic granular agent of these granulations be permeated for microbial inoculum dressing bacterium liquid, make the biological organic fertilizer of particle, improved added value of product, both for these enterprises have solved product overloading, found again the processing approach of another resource utilization for their wastewater treatment.
5, investment cost reduces, and to process 300-400T waste liquid (going out 10,000 ton/years of scales of xylogen organic granular agent) day as example, its investment only needs more than 500 ten thousand yuan, is about 1/5 of traditional alkali recovery.Therefore, less investment is that present technique obtains extensively to use the sharpest edges of promoting.
6, raw material is easy to get, technique is simple, take effect faster with respect to traditional organic granular agent, become thoroughly decomposed with feces of livestock and poultry production organic granular agent fully fermenting and need 7-10 days, and take large-area place, Compost on Soil pollutes, can waste natural resources with humic acid, and the exploitation vegetation destruction, and do not dissolve, fertilizer efficiency is low.Simple with xylogen organic granular agent production biological organic fertilizer production technique, raw material is sufficient, can produce in enormous quantities.
7, fertilizer efficiency is fast, be beneficial to the raising utilization rate of fertilizer: its effective constituent overwhelming majority of this xylogen organic granular agent more traditional feces of livestock and poultry organic granular agent exists in the small molecules mode, reduced degradation process, and it is slow to hold the process that the agent of poultry manure organic granular is converted into Crop, take effect relatively slow, utilization ratio is low.
8, enlarged the use range of product: make biological organic fertilizer not only dissolve in the vegetables fruit tree and make base fertilizer and use, also can be used for the land for growing field crops and carry out machine sowing, also use can be mixed with granular composite fertilizer, improved the market competitiveness of product.

can find out from detected result: its living bacteria count quantity of the biological organic fertilizer product of producing after Mixed inoculation microbiobacterial agent in the agent of xylogen organic granular all reaches about 2,000 ten thousand/gram, organic 〉=more than 31%, granule strength is greater than 7N, granularity is all more than 90%, miscellaneous bacteria is no more than 10%, moisture is lower than 10%, indices is all considerably beyond the requirement of Ministry of Agriculture's industry standard, and its organic matter of biological organic fertilizer of producing with humic acid higher outside, other index is all lower than the biological organic fertilizer of producing with the agent of xylogen organic granular, show that moisture is high, granule strength is inadequate, granularity is low, the granulating effect is lower than the product with the agent of xylogen organic granular, and the miscellaneous bacteria rate is high, living bacteria count is low, overall target from granular bioorganic fertilizer, produce its quality product of biological organic fertilizer well below the biological organic fertilizer product of producing with the agent of xylogen organic granular with traditional humic acid, and energy consumption is large, waste natural resources, product cost is high, effect is slow.
Test example
Test is established three and is processed as follows respectively:
A: 100 kg/acres of biological organic fertilizers (agent of xylogen organic granular and powdery complex micro organism fungicide are compound)
B: 100 kg/acres of biological organic fertilizers (agent of xylogen organic granular and liquid composite microbial microbial inoculum are compound)
C: 100 kg/acres of biological organic fertilizers (humic acid is as organic granular agent raw material)
Residential quarter area 20m2 establishes 3 repetitions, and random district group is arranged.The trial crops tomato is tested fertile sample technical indicator mensuration and is seen Table 5, and all tests are processed and all made base manure, and manuring late and management are identical with habits fertilization.Data statistical approach: yield data is checked significance with duncan's new multiple range method.
Table 6 different treatment on tomato trunk blade, highly, the impact of climing transverse diameter
Table 6 can be found out: three different treatment to tomato grow the number of blade that B processes at most, transverse diameter rents most, the plant height that A processes is the highest, it is all minimum that C processes the number of blade, plant height, transverse diameter, illustrate with wood and plant the growth that the biological organic fertilizer that have the production of machine granule can promote tomato, its successful is better than the biological organic fertilizer product with humic acid production.
The impact of table 7 different treatment on tomato production
Table 7 can obviously be found out: A processes with B and processes relatively, and A processes output and also increases, but difference is not remarkable, illustrates that the biological organic fertilizer of producing with biological organic fertilizer and the powdery microbial inoculum of liquid bacterial agent production is little to tomato growth and yield effect.A processes and B processes all being significantly improved than C processing tomato, and effect of increasing production all reached utmost point conspicuous level, illustrates to use the biological organic fertilizer that this xylogen organic granular agent is produced more to be conducive to improve tomato production than the ordinary student organic fertilizer with humic acid production.
