Embodiment 1
[0045] A method of using biogas slurry to prepare pesticides for the prevention and treatment of leek maggots, adding flocculant to the biogas slurry after passing through a 200-mesh sieve, stirring evenly, and standing for 5 hours, then taking the supernatant and adding Chinese medicine liquid to the supernatant Mix evenly to obtain the pesticide, and the volume ratio of the supernatant to the traditional Chinese medicine liquid is 2:1.
[0046] The quality of each raw medicinal material in the Chinese medicine liquid is: Humulus 15kg, Atractylodes 8kg, honeysuckle 26kg, purslane 18kg, walnut leaf 11kg, phoenix crown grass 3kg, swallowtail 16kg, bamboo leaf plantain 14kg and red-backed vine 12kg.
[0047] The biogas slurry was taken from the fermentation tank of Heishizi Food Waste Treatment Plant in Chongqing, which had normal gas production for more than 3 months and used food waste for fermentation.
[0048] The flocculants are polyaluminum chloride and polyacrylamide. The...
