Problems solved by technology

[0005] In addition, the long-term use of chemical fertilizers will lead to problems such as land degradation and salinization, and the use of chemical pesticides will also greatly enhance the resistance of plants to soil-borne diseases, making it difficult to control plant diseases

Embodiment 1

[0044] Treatment of control group 1:

[0045] 1) Joint transformation stage control group:

[0046] The chicken manure is laid in the transformation tank with a laying thickness of 10cm and treated for 13 days.

[0047] Measure the temperature at 5cm below the surface of the material every day, and take the average temperature at three points; take samples and mix them at five points after turning over the material every two days, and dry some fresh samples in a 60°C oven to measure the water content, organic matter content, nitrogen, phosphorus, and potassium Content and other indicators, and another part of the fresh samples were used to measure pH value, decomposing degree, enzyme activity and other indicators.

[0048] 2) Aerobic fermentation stage control group:

[0049] The chicken manure and rice bran in step 1) are mixed according to insect manure: rice bran=9:1 (mass ratio), and then stacked into a cone with a ground diameter of 2m and a height of 1m for aerobic fer...

Embodiment 2

[0073] A method for jointly transforming chicken manure with light-spotted soldier flies and microorganisms, comprising the steps of:

[0074] 1) Joint transformation stage:

[0075] The combined transformation bacteria agent is inoculated in chicken manure according to 1‰ (w / w). After the materials are mixed evenly, they are laid in the transformation tank with a thickness of 10cm. The larvae are evenly sprinkled on the surface of the material, and the mature larvae and insect feces are separated after 13 days of transformation;

[0076] Measure the temperature at 5cm below the surface of the material every day, and take the average temperature at three points; take samples and mix them at five points after turning over the material every two days, and dry some fresh samples in a 60°C oven to measure the water content, organic matter content, nitrogen, phosphorus, and potassium Content and other indicators, and another part of the fresh samples were used to measure pH value,...

Embodiment 3

[0085] The results of the different treatments of the joint transformation phase:

[0086] The result shown in this embodiment is the situation after control group 1, control group 2 and embodiment 2 complete step 1):

[0087] Table 1 The harvest of mature larvae and material of Soldier Fly light spot in the joint transformation stage

[0088]

[0089]

[0090] Note: Different letters in the same row of data indicate significant differences (P0.05). The same as the following table.

[0091] As can be seen from Table 1, the chicken manure reduction rate of control group 1 is 8.08%, the chicken manure reduction rate of control group 2 is 35.75%, and the chicken manure reduction rate of embodiment 2 is 40.54%. sexual difference. The chicken manure reduction rate of control group 1 may be the result of microbial action, and the chicken manure reduction rate of embodiment 2 is significantly higher than that of control group 2, indicating that Bacillus subtilis BSF-CL can pr...

Abstract

The invention discloses a method using Hermetia illucens and microorganisms to jointly convert chicken manure. The method includes: using the Hermetia illucens and the microorganisms to jointly convert chicken manure, and subjecting chicken manure residues to aerobic fermentation by decomposing microbial inoculums and secondary fermentation by functional microorganisms. By the method, chicken manure accumulation can be reduced greatly, and the decomposing cycle is shortened; produced Hermetia illucens mature larvae can be used for producing protein feed, and microbial organic fertilizer produced by larva manure after joint conversion is high in fertilizer efficiency and can resist common soil-borne plant diseases.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for jointly transforming chicken manure with light-spotted soldier flies and microorganisms. [0002] technical background [0003] With the increase of society's demand for eggs and chicken, the chicken industry has developed rapidly, and the amount of chicken manure that follows has also continued to rise. According to the statistics of the National Bureau of Statistics, the number of poultry slaughtered reached about 11.9 billion in 2013, and this number is still rising. Chicken manure is rich in easily biodegradable organic matter, nutrients, and pathogenic bacteria. If it is not handled properly, it will become one of the main sources of pollution. [0004] The traditional treatment method of livestock and poultry manure is composting, which kills pathogenic microorganisms and is used as crop fertilizer. However, the current composting process faces a serie...
