Description

A kind of preparation method of the charcoal base microbe slow release fertilizer of EM bacterium fermented stalk

Technical field

The present invention relates to compost made of stalks production field, and in particular to a kind of charcoal base microbe slow release fertilizer of EM bacterium fermented stalk Preparation method.

Background technology

Biomass carbon be by biological materials such as agricultural crop straw, wood chips under the environmental condition of limitation or starvation, Through being pyrolyzed obtained solid product.Using the biomass carbon that agricultural crop straw the like waste is prepared into because content of ashes is higher, It can be subject to certain restrictions in industrial circle application, and can extensive use on agriculture field.Suitably apply bio-bacterial manure Fertilizer efficiency, controlling disease and rehabilitating soil can be improved, is to realize one of necessary ways of agricultural sustainable development.Produce it is low into Originally, the microbial manure of high prebiotic bacterial content has wide market prospects, also meets very much the development plan of China's green agriculture Slightly.

The content of the invention

The present invention solves the technical problem of provide a kind of charcoal base microbe slow release fertilizer of EM bacterium fermented stalk Preparation method, the fertilizer slow release performance according to this method preparation is good and can suppress soil fungi disease.

The technical problems to be solved by the invention are realized using following technical scheme：

The preparation method of the charcoal base microbe slow release fertilizer of a kind of EM bacterium fermented stalk, it is characterised in that carry out according to the following steps：

（1）Bacillus solid fermentation process：

80-85% furfural dregs, 8-10% waste saccharide liquids and 4-5% wheat bran are mixed, regulation is during initial water is divided into 58-60%, initial pH is Property, with after gauze tying under the conditions of 114-116 DEG C moist heat sterilization 20-22min, be cooled to 28-32 DEG C of inoculation bacillus, it is permanent Once, solid fermentation microbial inoculum is made in temperature fermentation 3-6d, daily turning；

（2）Fermented maize stalk：

1-3cm segment is cut into after 40-50 parts maize straw is dried with pulverizer, selects draughty fermentation field of taking shelter from rain Ground, gutter is dug, to control temperature be 12-14 DEG C, humidity 59-61%, after EM bacterium, nitrogen source and water are fully mixed, is spilled into powder In broken maize straw, carbon-nitrogen ratio 30:1, mixing is sufficiently stirred, the straw that depth is 38-40cm, width is 1.4-1.5m are made Stalk fermentation heap, weekly turning once, are fermented 4-6 weeks；

（3）The preparation of charcoal base microbe slow release fertilizer：

40-50 part rice straws are dried to constant weight under the conditions of 40-42 DEG C, after cutting and grinding, through 500-600 DEG C of continuous pyrolysis Device heating charing 3-5h, crushed 40 mesh sieves, is cooled to room temperature, obtain straw biomass charcoal；

By its with（1）（2）Middle resulting material, 6-8 parts binding agent, 5-10 part water are well mixed, and are placed in mould, are existed with tablet press machine Tabletting is carried out under 5-7MPa briquetting pressures, constant weight is dried to then at 40-45 DEG C, obtains the fertilizer.

Wherein, step（1）Middle bacillus is bacillus subtilis or bacillus licheniformis, and inoculum concentration is 5 × 10⁶CFU/ g.Step（2）Middle nitrogen source is duck excrement, urea, ammonium sulfate 2:3:3 mixing.Step（3）Middle binding agent be sodium carboxymethylcellulose or Oxidized starch.

The present invention reaction mechanism and have the beneficial effect that：

Using furfural dregs, waste saccharide liquid and wheat bran as solid fermentation raw materials, adjust moisture after mixing and pH, moist heat sterilization are followed by kind of a gemma Bacillus fermentation, low cost, the solid fermentation microbial inoculum of high content is made, soil fungi can be suppressed, the various soil faxes of crop can be prevented and treated Fungus diseases；Crushed after maize straw is dried, control temperature and humidity, be spilled into the mixture of EM bacterium, nitrogen source and water, adjust carbon nitrogen Than, fermentation reactor system, compost is into sepia, free from extraneous odour, available for ecological improved soil, can effectively reduce crops the incidence of disease and Disease index；Cutting and grinding after rice straw is dried, through pyrolysis installation heat carbonize, be made straw biomass charcoal, by its with Solid fermentation microbial inoculum, fermented maize stalk, binding agent and water mix, and are placed in tabletting in mould, obtain the fertilizer, fertilizer into Type performance is good, good mechanical performance, sustained release performance are excellent.

Embodiment
