Embodiment 1

[0022] This silkworm excrement organic fertilizer is made of 50kg of fungal chaff, 50kg of decomposed and fermented silkworm excrement, 20kg of high-temperature treated fish scales, 20kg of phosphate fertilizer, and 10kg of potassium fertilizer;

[0023] Its preparation method is:

[0024] A. Preparation of decomposed and fermented silkworm excrement: spread 90 kilograms of silkworm excrement on the ground with a thickness of 20 cm; mix 20% oligosaccharides and dry yeast at a ratio of 300:1 and stir evenly to obtain fermentation Spray the fermented liquid on the laid silkworm excrement until the silkworm excrement is completely soaked, then cover it with a plastic film for fermentation, open the film after 20 days of fermentation and turn it over, cover it and continue to ferment for 15 days , that is;

[0025] B. Preparation of fungus bran: Mix 60 kg of wet sugarcane broken leaves with 20 kg of filter mud, 0.5 kg of superphosphate, 1 kg of rice bran and 1 kg of gypsum, and t...

Embodiment 2

[0029] The silkworm excrement organic fertilizer is made of 70 kg of fungus chaff, 80 kg of decomposed and fermented silkworm excrement, 30 kg of high-temperature treated fish scales, 10 kg of phosphate fertilizer, and 20 kg of potassium fertilizer;

[0030] Its preparation method is:

[0031] A. Preparation of decomposed and fermented silkworm excrement: spread 100 kilograms of silkworm excrement on the ground with a thickness of 18 cm; mix oligosaccharides and dry yeast with a concentration of 20% in a ratio of 300:1 and stir evenly to obtain Fermentation liquid, spray the fermentation liquid on the laid silkworm excrement until the silkworm excrement is completely wet, then cover it with a plastic film for fermentation, open the film after 20 days of fermentation and turn over the pile, cover it and continue to ferment for 15 days after turning over the pile God, get it;

[0032] B. Preparation of fungus bran: Mix 90 kg of wet sugarcane broken leaves with 30 kg of filter m...

Abstract

The invention discloses an organic silkworm excrement fertilizer and a preparation method thereof, and relates to the technical field of organic biofertilizers. The organic silkworm excrement fertilizer is prepared from 25-35 parts of mushroom bran, 25-40 parts of composted and fermented silkworm excrement, 10-15 parts of fish scales treated at a high temperature, 5-10 parts of phosphatic fertilizer and 5-10 parts of potassic fertilizer. The preparation method comprises the following steps: uniformly mixing the composted and fermented silkworm excrement and the mushroom bran, piling for natural fermentation for 5 days, adding the phosphatic fertilizer and the potassic fertilizer, uniformly mixing, granulating and drying to obtain the organic silkworm excrement fertilizer. The organic silkworm excrement fertilizer is high in organic matter content, contains comprehensive nutrients through combination of the silkworm excrement and the fish scales treated at high temperature, is long in the fertilizer effect, and can promote the growth of fruits and vegetables, shorten the cultivating time and reduce the cultivating cost.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, in particular to a silkworm excrement bio-organic fertilizer with silkworm excrement and fungus chaff as main raw materials and a preparation method thereof. Background technique [0002] my country is the largest sericulture country in the world. Sericulture excrement is a mixture of solid feces discharged by silkworm larvae during sericulture and mixed with leftover mulberry and bedding in silkworm seats. It contains rich nutrients and a small amount Physiological regulator of crop growth, the dry matter of silkworm feces contains 77.68-81.15% of organic matter, 2.97% of nitrogen, 1.03% of phosphorus, 3.52% of potassium and other trace elements, and has good agricultural value. [0003] At present, the treatment of silkworm excrement is generally directly used as farmland fertilizer or discarded, but because fresh silkworm excrement contains certain pathogenic bacteria, directly ...
