Embodiment 1

[0022] A method for rapidly fermenting silkworm excrement organic fertilizer, the operation is as follows:

[0023] (1) Spreading compound bacteria: within 4 hours after the cocoons are clustered, the compound bacteria are evenly removed on the surface of the silkworm excrement, and then within 4 hours, the silkworm excrement sprinkled with the compound bacteria is carried out to the next process;

[0024] (2) Stacking and fermentation: Stack the silkworm excrement mixed with compound bacteria on the flat ground. When stacking, the surface forms an ellipse, and the stacking height is 120 cm. When stacking, it is not compacted or covered with a film. Keep the silkworm excrement loose, ventilated, and fermented. Prevent water from entering, rain and sun protection;

[0025] (3) Re-fermentation: When the stacking fermentation time reaches 12 hours, the silkworm excrement will automatically heat up to 60-70 degrees, indicating that the fermentation is successful. Mix the silkworm ...

Embodiment 2

[0032] A method for quickly fermenting silkworm excrement organic fertilizer, the basic operation is:

[0033] (1) Spreading the compound bacteria: within 4 hours after the cocoons are clustered, the compound bacteria are evenly sprinkled on the surface of the silkworm excrement, and then within 4 hours, the silkworm excrement sprinkled with the compound bacteria is carried out in the next process;

[0034](2) Stacking and fermentation: stack the silkworm excrement mixed with compound bacteria against the wall. When stacking, the surface forms a semi-elliptical shape. Breathable, prevent water from entering during fermentation, prevent rain and sunscreen;

[0035] (3) Re-fermentation: When the stacking fermentation time reaches 20 hours, the silkworm excrement will automatically heat up to 60-70 degrees, indicating that the fermentation is successful. Mix the silkworm excrement and ferment it again. The re-fermentation time is 12 hours, and the silkworm excrement can remove th...

Embodiment 3

[0042] A method for rapidly fermenting silkworm excrement organic fertilizer, comprising the steps of applying compound bacteria, stacking fermentation and re-fermentation, the basic operations of which are as follows:

[0043] (1) Spreading the compound bacteria: within 4 hours after the cocoons are clustered, the compound bacteria are evenly sprinkled on the surface of the silkworm excrement, and then within 4 hours, the silkworm excrement sprinkled with the compound bacteria is carried out in the next process;

[0044] (2) Stacking and fermentation: Stack the silkworm excrement mixed with compound bacteria on the flat ground. When stacking, the surface forms a circle, and the stacking height is 130 cm. When stacking, it is not compacted or covered with a film. Prevent water from entering, rain and sun protection;

[0045] (3) Re-fermentation: The stacking fermentation time reaches 18 hours, and the silkworm excrement will automatically heat up to 70 degrees, indicating that...

Abstract

The invention discloses a method for quickly fermenting a silkworm excrement organic fertilizer. The method comprises the following steps: inputting 10-20kg of compound bacteria per 1000kg of silkworm excrements within 4 hours after mounting silkworm cocoons on a cocooning frame; uniformly scattering the compound bacteria on the surface of silkworm excrements; then, stacking the silkworm excrements with the compound bacteria next to a wall or on a flat ground within four hours, wherein during stacking, an ellipse or a circle is formed on the surface, the stacking height is over 100cm, the silkworm excrements cannot be compacted during stacking and cannot be covered by a film, are kept loose and ventilating, water is prevented from entering during fermentation and rain proofing and sun proofing are needed; and when the stacking fermentation time reaches 10-20 hours, overturning and stirring the silk excrements when the temperature of the silkworm excrements automatically raises to 60-70 DEG C, and then fermenting again 10-14 hours till the silkworm excrements are completely fermented to obtain the silkworm excrement organic fertilizer. The method disclosed by the invention is simple to operate and feasible, short in fermentation time and high in production efficiency. The silkworm excrement organic fertilizer is granular, is high in quality and good in application effect and has relatively good economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to an organic biological fertilizer, in particular to a method for rapidly fermenting silkworm excrement organic fertilizers. Background technique [0002] Silkworm fece (silkworm fece), also known as silkworm excrement and silkworm feces, was called evening silkworm excrement, two silkworm excrement, and silkworm arrow in ancient times. It is the excrement of silkworm (Bombyx mori L.) larvae after eating mulberry leaves. The main components of silkworm excrement are carbohydrates and crude fiber, and it is a kind of weakly alkaline fertilizer. Dried silkworm excrement is short cylindrical, with slightly flattened ends, 2-5mm long and 1.5-3mm in diameter. Dark black, rough surface, with 6 obvious longitudinal ribs and 3-4 horizontal light lines, which are hexagonal. Hard and brittle, easily shattered when wet. Slightly grassy. It is mainly produced in Guangxi, Jiangsu, Zhejian...
