Description

Multielement composite microbe fertilizer and its production method
Technical field
The present invention relates to a kind of composite fertilizer, more particularly to one kind using potassium feldspar as primary raw material, rich in efficient to potassium feldspar The multiple element composite microbe fertilizer and its production method of potassium decomposing, Soluble phosphorus and nitrogen-fixing microorganism.
Background technology
Growth and development of plants needs the different element of a variety of quantity, it is especially desirable to substantial amounts of nitrogen, phosphorus, potassium element.To meet People's demand growing to various plants, traditional organic fertilizer obviously can not meet the needs of plant, therefore, industrial metaplasia It is considered as to realize this purpose main path always to produce substantial amounts of nitrogen, phosphorus, potassium chemical fertilizer.However, with fertilizer application amount Continuous increase, its negative effect is increasingly apparent, outstanding behaviours be the hardening soil, soil degradation, soil and underground water it is seriously dirty Dye, soil texture and microbiota and diversity by destroy, crops quality declines, it is serious when jeopardize food security Deng.So many limitations have been made in use of the World Food Programme to chemical fertilizer, some developed countries and regions even start to prohibit Only use chemical fertilizer.
As the development of science and technology and the control increasingly increased of Environmental are paid attention to, China is in novel plant fertilizer Also substantial amounts of work has been made in research and development.It has been reported that and the various new-type fertilizers that use it is a lot, have and planted with corruption Organic fertilizer based on acid, have one or more microorganism groups into composite microbe fertilizer, have biology with mineral compound fertilizer etc..This hair It is bright to belong to one of biology and mineral compound fertilizer.CN100343202C discloses a kind of biological multi element phosphorus potassium ferbilizer, and potassium shale is crushed Dissolving phosphor and dissolving potassium bacterium after fermentation is added afterwards to be made, is less containing element the defects of the fertilizer, and effective potassium content is also insufficient.Application People discloses a kind of biological mineral compound fertilizer and its production method (CN101475417A), by 70%-80% potassium shale powder with 20%-30% humic acid is made after the fermentation of potassium decomposing, phosphorus decomposing and ferment bacterium, and due to existing, the ability of potassium solubilizing bacteria is weaker and potassium shale The problems such as accounting in composite fertilizer is larger, cause effective potassium for being discharged from potassium shale relatively low, the improvement soil of composite fertilizer Combination property is smaller, and application is subject to certain restrictions.Further to improve the utilization rate of potassium shale, fertilizer efficiency is improved, is improved The combination property of composite fertilizer, expand application, applicant screens wild type indigenous strain from mining area, and has carried out mutation breeding Studied with fermentation technique, it was found that the powerful bacterial strain of ability of dissolving potassium, and this application and development is gone out into multielement composite microbe fertilizer.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of multielement composite microbe fertilizer and its production method, and this is more Elements compounding microorganism fertilizer improves the utilization rate of potassium shale, improves the combination property of composite fertilizer, improves fertilizer efficiency, expands Application.
In order to solve the above technical problems, the potassium shale and humic acid rich in potassium oxide that the applicant location abounds with are original Material, the colloid bacillus cereus using the powerful deposit number of ability of dissolving potassium as CGMCCNo.8481(Bacillus mucilaginosus)HSCUP-76-8 as potassium decomposing strain, using the strong deposit number of dissolving P capacity as CGMCC No.4296's Bacillus megaterium (Bacillus megaterium) as phosphorus decomposing strain, using deposit number as CCTCC M207197 not Blue kirschner bacterium (Frankia.sp) fgc6 bacterial strains are as fixed nitrogen strain, after carrying out fermented and cultured to potassium shale and humic acid respectively, It is made rich in the multielement composite microbe fertilizer based on potassium.
