High stalk digestic property, first cation resin catalyzing agent surface acidic groups contacts with straw, is little by straw degradative
Molecular polysaccharide, micromolecular polysaccharide enters catalytic inner subsequently, is degraded to little molecule monosaccharide further, and fermentation tank uses pressure arteries and veins
Dynamic solid state fermentation tank, greatly reduces the toxicity evaluation of Bt biological pesticide, can prepare well by being processed straw
Go out excellent BT biological pesticide, can well be applied in agriculture and animal husbandry fruit-bearing forest, effectively kill off the insect pests, it is to avoid crop straw burning causes
Environmental pollution, well make use of straw, be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is the flow chart of a kind of method preparing Bt biological pesticide with straw for raw material of the specific embodiment of the invention.
Detailed description of the invention
Below, by specific embodiment, technical scheme is described in detail.
Embodiment:
With reference to Fig. 1, the present invention proposes a kind of method preparing Bt biological pesticide for raw material with straw, comprises the following steps:
S1, pretreatment for stalk: after collecting stalk, soak dry in the sun, pretreatment is carried out for stalk, makes
Obtain stalk effective ratio area to increase, Physical pretreatment such as mechanical activation comminution, can be well by the fibre in fibrous raw material
Dimension element efflorescence, softening, but this method is when for the process of straw, and effect is poor, here increases effective ratio area
Method use chemical method, utilize mineral acid for stalk soak so that in stalk, native cellulose dissolves and drops
Solve, improve stalk digestic property；
S2, stalk is hydrolyzed into can zymolysis sugar: stalk is added in hydrolytic tank, heat hydrolytic tank to 120 DEG C, keep
Temperature-resistant, add catalyst, solid-to-liquid ratio is 1:3, reacts 3h, catalyst cation resin catalyst, cation resin catalyzing
First agent surface acidic groups contacts with straw, is micromolecular polysaccharide by straw degradative, and micromolecular polysaccharide enters catalyst subsequently
Inside, is degraded to little molecule monosaccharide further, is sugar by the cellulose degradation in stalk, can so that zymolysis afterwards,
Heating pool heating rate is 12-15 DEG C/min；
S3, for the solidification of raw material after hydrolysis: after the stalk taking-up that will hydrolyze, after addition solid-state carrier, put into centrifugal
Being stirred in agitator, solid-state carrier is the one of Testa Tritici, Testa oryzae, soybean cake powder, peanut cake powder, expanded perlite and distiller's grains of beer
Kind, centrifugal stirrer rotary speed is 16000-18000r/min；
S4, the solidification fermentation of straw: being added in fermentation tank by the raw material being cured, carry out solidification fermentation, fermentation tank uses pressure
Pulsation solid state fermentation tank, holding pressure is 0.25-0.32MPa, effectively reduces the toxicity evaluation of Bt biological pesticide；
S5, the molding of fertilizer: being taken out by the raw material fermented and dry, be shaped in adding fertilizer forming machine, flash-off time is
24-36h so that raw material can keep being dried, it is simple to forming machine completes the molding of pesticide.
The method increasing effective ratio area in the present invention uses chemical method, utilizes mineral acid to soak for stalk,
In making stalk, native cellulose dissolves and degrades, and improves stalk digestic property, cation resin catalyzing agent surface
First acidic-group contacts with straw, is micromolecular polysaccharide by straw degradative, and micromolecular polysaccharide enters catalytic inner subsequently, enters
One step is degraded to little molecule monosaccharide, and fermentation tank uses pressure fluctuation solid state fermentation tank, greatly reduces the poison of Bt biological pesticide
Power titer, can prepare excellent BT biological pesticide well by being processed straw, can well be applied to agriculture and animal husbandry fruit
In woods, effectively kill off the insect pests, it is to avoid the environmental pollution that crop straw burning causes, well make use of straw, be worthy to be popularized.
