Example Embodiment

[0022] Example 1:

[0023] This silkworm excrement organic fertilizer is made of 50 kg of fungus residue, 50 kg of decomposed and fermented silkworm excrement, 20 kg of high-temperature treated chicken manure, 20 kg of phosphate fertilizer, and 10 kg of potash fertilizer;

[0024] The preparation method is:

[0025] A. Preparation of decomposed and fermented silkworm excrement: Spread 90 kilograms of silkworm excrement on the ground with a thickness of 20 cm; mix oligosaccharides and dry yeast with a concentration of 20% in a ratio of 300:1 and stir to obtain fermentation. Spray the fermentation broth on the spread silkworm excrement until the silkworm excrement is completely wet, and then cover it with plastic film for fermentation. After 20 days of fermentation, open the film and turn the pile. After the pile is turned, cover it and continue fermentation for 15 days. , That is;

[0026] B. Preparation of mushroom bran: Mix 60 kg of moist sugarcane leaves with 20 kg of filter mud, 0...

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 chicken manure treated at a high temperature, 5-10 parts of a phosphatic fertilizer and 5-10 parts of a 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 the combination of the silkworm excrement and the chicken manure treated at high temperature, is long in 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 ...
