(1) nutrient agar and deionized water are fitted into Roche bottle, are 100 DEG C in temperature, pressure goes out under conditions of being 0.15MPa
Bacillus subtilis and silicate bacteria are added in Roche bottle respectively by bacterium 30min, 35 DEG C at a temperature of cultivate 50h, formed
Spore liquid；
(2) spore liquid is added in fermentor, controlled at 45 DEG C, ventilatory capacity 300m3/ h, fermentor revolving speed are 100r/
Fermentation liquid is made in min, fermentation time 10h；
(3) revolving speed by the fermentation liquid of mixed bacillus subtilis and silicate bacteria in 10000r/min is centrifuged
3min collects bacterium mud, and 10% glycerol is added, and is transferred to refrigerator pre-freeze, and pre-freeze speed control makes sample in 1 DEG C of decline per minute
- 35 DEG C~-40 DEG C are frozen into, is transferred in freeze drier later in -45 DEG C of dry 10h, complex micro organism fungicide is made.
6. a kind of preparation method of biological organic chemical fertilizer, which comprises the steps of:
Step S1, modification bamboo charcoal, calcium carbonate are ground, crosses 80 meshes, be added in deionized water and be uniformly mixed, 10% dilute salt is added
Acid for adjusting pH filters after stirring 3h until pH is 5.5,75 DEG C of heating water baths and carries out magnetic agitation with the revolving speed of 120r/min,
It is washed with deionized three times, is transferred in 85 DEG C of drying boxes dry 45min, mixture is made, it is spare；
Step S2, urea, ammonium sulfate and 3% potassium nitrate solution are mixed, 45 DEG C of heating water baths and ultrasonic vibration 15min, control
Supersonic frequency is 25KHz, and 10% dilute hydrochloric acid is added and adjusts pH, until pH is 5.6, is warming up to 65 DEG C, and turn with 100r/min
Speed carries out magnetic agitation, stirs 30min, and A liquid is made；
Step S3, mixture prepared by step S1 is mixed with compound bio bacteria preparation, is transferred in A liquid, with 240r/min's
Revolving speed stirs 15min, and 80 DEG C of dry 6h are crushed later, is granulated, drying, and the biological organic chemical fertilizer that partial size is 3-5mm is made.
