Embodiment 1

[0016] A kind of method of preparing earthworm breeding substrate of the present embodiment is as follows:

[0017] Take 60kg of fresh pig manure and mix evenly with 40kg of edible fungus residues, the edible fungi residues are the remaining residues of cultivated saprophytic woody fungi and / or fecal fungi. Eliminate larger impurities and stones, adjust the water content to 70-80%, pile up about 0.4m in height, cover the surface with film, and ferment under anaerobic conditions at a fermentation temperature of 55-60°C, turning over every 3 days during the period Heap, replenish water at the same time, anaerobic fermentation time is 25 days and earthworm breeding substrate can be obtained. Fill the substrate into the reaction box, inoculate 1.8 kg of mature earthworms per cubic meter, and the species of earthworms is Daping No. 2.

Embodiment 2

[0019] A kind of method of preparing earthworm breeding substrate of the present embodiment is as follows:

[0020] Take 70kg of fresh pig manure and mix evenly with 30kg of edible fungus residues, the edible fungi residues are the remaining residues of cultivated saprophytic woody fungi and / or fecal fungi. Eliminate larger impurities and stones, adjust the water content to 70-80%, pile up about 0.4m in height, cover the surface with film, and ferment under anaerobic conditions at a fermentation temperature of 50-55°C, turning over every 3 days during the period Heap, replenish water at the same time, anaerobic fermentation time is 30 days and earthworm breeding substrate can be obtained. Fill the substrate into the reaction box, inoculate 2.0 kg of mature earthworms per cubic meter, and the species of earthworms is Daping No. 2.

Embodiment 3

[0022] A kind of method of preparing earthworm breeding substrate of the present embodiment is as follows:

[0023] Get 80kg of fresh cow dung and 20kg of edible fungus residues and mix evenly, and the edible fungi residues are the remaining residues of cultivated saprophytic woody fungi and / or fecal fungi. Eliminate large impurities and stones, adjust the water content to 70-80%, pile up about 0.4m in height, cover the surface with film, and ferment under anaerobic conditions at a fermentation temperature of 50-60°C, turning over every 4 days during the period Heap, replenish water at the same time, anaerobic fermentation time is 25 days and earthworm breeding substrate can be obtained. Fill the substrate into the reaction box, inoculate 2.1 kg of mature earthworms per cubic meter, and the species of earthworms is Daping No. 2.

Abstract

The invention discloses a method for preparing earthworm cultivation substratum. By mixing livestock dung and edible fungus residue without foreign matters to carry out anaerobic fermentation, the method obtains the substratum for cultivating and reproducing earthworms, the livestock dung is pig dung or cow dung or the mixture of pig dung and cow dung, and the edible fungus residue is residue which is left over in the growth of cultured saprophytic lignicolous fungi or coprophilous fungi. Since the method utilizes the livestock dung and the edible fungus residue as the cultivation substratum to raise the earthworms, the method not only solves the problem of dung accumulation and waste and prevents environment pollution, but also increases the cultivation scale and growth quality of the earthworms by adding the edible fungus residue, thus effectively increasing the output of the earthworms.

Description

technical field [0001] The invention relates to the field of animal feed preparation, in particular to a method for preparing an earthworm breeding substrate. Background technique [0002] Earthworms are annelids, oligochaetes, hermaphroditic, heterozygous, nocturnal, feed on livestock and poultry manure and organic waste, swallow them together with soil, and also eat plant stems and leaves and other debris. Earthworms can loosen the soil, improve the soil, increase fertility, and promote agricultural production. Earthworms are called earthworms in traditional Chinese medicine, and the "Compendium of Materia Medica" claims that they have the functions of dredging meridians, activating collaterals, promoting blood circulation and removing blood stasis, and preventing and treating cardiovascular and cerebrovascular diseases. Earthworms can also be used as high-quality protein feed for livestock and poultry and aquaculture. The demand for earthworm breeding is small and the e...
