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...
