Embodiment 1
[0022] A bio-pesticide, the weight ratio of each component is based on the total weight of raw materials, respectively: 65% of corn stalks, 25% of corncobs, 2.5% of wormwood, 5% of pumpkin stems and leaves, and 2.5% of dandelion.
[0023] The preparation method is as follows: measure various raw materials in proportion, pulverize and stir to mix, and steam sterilize (Systec HX-540 cabinet autoclave) after mixing, and then add Bacillus amyloliquefaciens seed liquid to the raw materials and mix them Carry out solid-state fermentation, the fermentation temperature is 25-30 DEG C, and the fermentation time is 7-15 days. After taking it out, dry it and grind it through a 20-mesh sieve to get the product.
Embodiment 2
[0025] A biopesticide, the weight ratio of each component is based on the total weight of raw materials, respectively: 60% of corn stalks, 30% of corn cobs, 2.5% of wormwood, 5% of pumpkin stems and leaves, and 2.5% of dandelion.
[0026] The preparation method is as follows: measure various raw materials in proportion, pulverize and stir to mix, and steam sterilize (Systec HX-540 cabinet autoclave) after mixing, and then add Bacillus amyloliquefaciens seed liquid to the raw materials and mix them Carry out solid-state fermentation, the fermentation temperature is 25-30 DEG C, and the fermentation time is 7-15 days. After taking it out, dry it and grind it through a 20-mesh sieve to get the product.
Embodiment 3
[0028] A biopesticide, the weight ratio of each component is based on the total weight of raw materials, respectively: 55% of corn stalks, 30% of corncobs, 2.5% of wormwood, 10% of pumpkin stems and leaves, and 2.5% of dandelion.
[0029] The preparation method is as follows: measure various raw materials in proportion, pulverize and stir to mix, and steam sterilize (Systec HX-540 cabinet autoclave) after mixing, and then add Bacillus amyloliquefaciens seed liquid to the raw materials and mix them Carry out solid-state fermentation, the fermentation temperature is 25-30 DEG C, and the fermentation time is 7-15 days.
