Problems solved by technology

Its disadvantage is that this method adds a large amount of plant fiber components such as distiller's yeast, crop straw powder, chaff powder, sawdust powder and bacterial buds in addition to cow dung, which prolongs the decomposing time to a certain extent and cannot achieve rapid decomposing, so it is not applicable For rapid treatment of fresh cow dung in cattle farms

Embodiment 1

[0018] The preparation method of the decomposed cow dung culture material for cultivating earthworms in embodiment 1, the steps are as follows:

[0019] (1) Fermentation of fresh cow dung: use 13 kg of fermented strains per 1 ton of fresh cow dung, add 40 kg of water, add 0.8 kg of brown sugar in the water, and spray the fermented strains directly on the dung pile until the bottom water seeps out. Fermentation under anaerobic conditions;

[0020] (2) adjust the pH value: adjust the pH value of the fresh cow dung after fermentation to 6.5-7.5 to obtain the culture material;

[0021] (3) Reconcile feed nutrients and add nutrients: for every 1 cubic meter of culture material, take 100 kg of water to dissolve 0.65 kg of urea, 8 grams of saccharin and 6 grams of pineapple essence, first pour half of it on the culture material, turn over After the pile, the other half is also poured on the culture medium, and it can be used after 2-3 days.

[0022] The fermentation strain used was...

Embodiment 2

[0024] Embodiment 2 The preparation method of the decomposed cow dung culture medium for cultivating earthworms is the same as that in Embodiment 1, but step (2) is omitted.

Embodiment 3

[0025] The preparation method of the decomposed cow dung culture material for cultivating earthworms in embodiment 3, the steps are as follows:

[0026] (1) Fermentation of fresh cow dung: use 17 kg of fermented strains per 1 ton of fresh cow dung, add 50 kg of water, add 1.2 kg of brown sugar in the water, and spray the fermented strains directly on the dung pile until the bottom water seeps out. Fermentation under anaerobic conditions;

[0027] (2) adjust the pH value: adjust the pH value of the fresh cow dung after fermentation to 6.5-7.5 to obtain the culture medium;

[0028] (3) Reconcile feed nutrients and add nutrients: for every 1 cubic meter of culture material, take 100 kg of water to dissolve 0.65 kg of urea, 8 grams of saccharin and 6 grams of pineapple essence, first pour half of it on the culture material, turn over After the pile, the other half is also poured on the culture medium, and it can be used after 2-3 days.

Abstract

The invention discloses a preparation method of a decomposed cow dung culture medium for breeding earthworm. The preparation method comprises the following steps: fermenting fresh cow dung; adjusting pH value; uniformly stirring nutritive materials of the feed; and adding nutrition. The method can quickly solve the problem of quick dealing of cow dung of a large-sized cow farm and ensure short compost fermentation, sufficient fermentation of culture medium and no influence on the earthworm.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for preparing a decomposed cow dung culture medium for earthworm cultivation. Background technique [0002] In some metropolises such as Shanghai and Beijing, with the improvement of people’s lives, the demand for dairy products and beef increases, and the scale of cattle farms is relatively large, which will produce a large amount of cow dung every day, causing certain pollution to the environment and requiring investment in treatment. Cow manure, which increases the cost of the cattle farm. In addition, in recent years, in my country's livestock and poultry breeding industry, due to harmful feed additives and drug abuse, my country's animal husbandry products often encounter green barriers when entering the international market. The development of green agriculture has become an urgent problem to be solved. Earthworm farming can provide rich feed additives and ...
