Embodiment 1

[0016] (1) Fresh cow dung pretreatment: put fresh cow dung into a 75°C oven for 4 hours to reduce the water content in the dung to obtain dried cow dung; add peanut powder to the dried cow dung, peanut powder: bake The weight ratio of dry cow dung is 1:20, and it is stirred evenly to make a cow dung mixture. Put the cow dung mixture into the cement tank for natural fermentation for 12 hours to obtain fermented cow dung; the peanut powder is obtained by soaking the peanut kernels in hot water at 90°C for 30 minutes, then naturally air-drying, crushing, and passing through a 60-mesh sieve Powder.

[0017] (2) Inoculation of black soldier fly larvae: Spread the fermented cow dung on the indoor floor with a thickness of 10cm-15cm. Inoculate according to the density of inoculating 2g of black soldier fly larvae in 1 kg of fermented cow dung, spread the 8-day-old black water larvae evenly on the surface of fermented cow dung, set the room temperature at 28°C-30°C, and the relative ...

Embodiment 2

[0030] (1) Fresh cow dung pretreatment: put fresh cow dung into a 75°C oven for 4 hours to reduce the water content in the feces and obtain dried cow dung; add peanut powder to the dried cow dung, peanut powder: drying The weight ratio of cow dung is 1:30, and it is stirred evenly to make a cow dung mixture. Put the cow dung mixture into the cement tank for natural fermentation for 16 hours to obtain fermented cow dung; the peanut powder is obtained by soaking the peanut kernels in hot water at 90°C for 30 minutes, then naturally air-drying, crushing, and passing through a 60-mesh sieve Powder.

[0031] (2) Inoculation of black soldier fly larvae: Spread the fermented cow dung on the indoor floor with a thickness of 10cm-15cm. According to the density of inoculating 4g black soldier fly larvae in 1kg fermented cow dung, spread the 10-day-old black soldier fly larvae evenly on the surface of fermented cow dung, set the room temperature at 28°C-30°C, and the relative humidity o...

Abstract

The invention discloses a method for improving the treatment efficiency of hermetia illucens on cow manure by using peanut powder and belongs to the technical field of resources and environmental protection. The method comprises the following steps: placing fresh cow dung in an oven to be treated for 4h at the temperature of 75 DEG C, adding a certain amount of the peanut powder to prepare a mixture of the cow dung, inoculating hermetia illucens larvae after fermenting, controlling the temperature at 28 to 30 DEG C, and performing treatment for 15 to 18 days. The method disclosed by the invention is simple to operate and low in cost, can improve the degradation efficiency of the hermetia illucens on the cow dung, and has broad development prospects.

Description

technical field [0001] The invention relates to a manure treatment method, which belongs to the technical field of resources and environmental protection, and in particular to a method for improving the treatment efficiency of black soldier flies on cow manure by using peanut powder. Background technique [0002] my country's animal husbandry industry is changing from traditional farmers' free-range farming to large-scale, intensive and industrialized methods. According to statistics from the China Statistical Yearbook, from 2000 to 2016, my country's total meat output increased from 60.139 million tons to 85.378 million tons, and milk The total output of such products increased from 9.191 million tons to 37.121 million tons. While the production of livestock products has increased, the discharge of livestock and poultry manure has increased year by year. [0003] Livestock and poultry manure is rich in organic matter and nutrients such as nitrogen, phosphorus and potassium,...
