Problems solved by technology

[0002] The patent with the publication number CN101233835A discloses a method for cultivating earthworms with cow dung and crop stalks. The method uses fresh cow dung and straw powder as fermentation raw materials and distiller's yeast as fermentation bacteria. Although the method for cultivating earthworms can solve the problem of large-scale The problem of cow dung treatment in cattle farms has been realized, and the recycling of cow dung has been realized. However, this method has a long fermentation cycle for raw materials, and the nutritional value of earthworms cultured by fermentation needs to be improved.

Embodiment 1

[0013] Embodiment 1: Adopt prior art fermentation, apply gained fermented product to breed earthworm:

[0014] Crush corn stalks into fine powder, mix fresh cow dung, distiller's yeast, corn stalk powder, bran husk powder, sawdust powder and mushroom bag in a ratio of 100:5:15:20 by weight, and stack Ferment, turn over every 10 days and add water, ferment for 30 days to get fermented product.

[0015] The fermented product obtained in the above steps is used as the earthworm breeding substrate, and the amount of 40kg per m2 culture bed (bed height 0.5-0.8m, long 20-30m, bottom width 1-1.5m on the cross section, bottom width 1.5-2m) Lay it into the breeding bed, put 250-300 earthworms per square meter (the variety is Daping No. 2, the scientific name is Eisenia fetida), and the weight of each earthworm is 100-200mg. The earthworms are cultivated for 40-50 days, and the temperature of the culture substrate is controlled. At 20°C-25°C, the humidity is controlled at 60%-70%, and ...

Embodiment 2

[0017] Embodiment 2: Adopt technology of the present invention to ferment, apply fermented product of the present invention to cultivate earthworms:

[0018] 1, the preparation of breeding raw material: get the fresh cow dung of large-scale cattle farm (get final product through conventional sterilization treatment, need not dry process), with fresh cow dung and silage rice straw and silage corn stalk by weight 6: The ratio of 2:2 is mixed, and the straw is cut into small pieces of 1-4cm in advance. The silage is carried out in a sealed silo.

[0019] 2. Fermentation treatment of cultured raw materials: use 10% EM bacteria liquid for conventional natural composting and fermentation, and turn over every 5 days. On the first day of fermentation, the first turn and the second turn When adding 35-45m. Ferment for 15 days, spray 105-135mL per 1kg of breeding raw materials to obtain fermented product.

[0020] 3. Take the fermented product and carry out earthworm culture: use the...

Abstract

The invention discloses a leavening for cultivating earthworms and a method for cultivating earthworms. The leavening is prepared from fresh cow dung, rice straw and corn straw in parts by weight according to a ratio of 6:2:2 by virtue of mixing and fermenting. The leavening is obtained by respectively adding 35-45mL of EM bacterium solution with a mass percent of 10 percent in each kg of mixture of the fresh cow dung, the rice straw and the corn straw while fermenting for the first day, turning for a first time and turning for a second time by virtue of conventional natural piling and fermenting for 15 days. The fermentation time is short, and the fermentation is relatively full, and the leavening has no smell. The earthworms cultivated by applying the leavening are relatively high in nutritive value.
