Description

A method of cultivating earthworms with waste bacteria bag

【Technical field】

The invention relates to the field of animal breeding, in particular to a method for cultivating earthworms with waste bacteria bags.

【Background technique】

The waste mushroom bag is the waste produced by the production of edible fungi, mainly composed of edible mushroom residue, corn residue, cottonseed hulls, wheat husks and other organic plant residues. If it is discarded directly, it will harm the environment, but if it can be used, it may generate economic benefits.

Earthworms are common terrestrial annelids that live in the soil and come out at night. They feed on livestock and poultry manure and organic waste, swallowing them together with soil, and also eating plant stems and leaves. Earthworms can loosen the soil, improve the soil, increase fertility, and promote agricultural production. There are about 2,500 species of earthworms in the world, and 229 species have been recorded in our country, which are widely distributed and have many types. There are more than 2,000 species in our country. Earthworms have the functions of dredging meridian and activating collaterals, promoting blood circulation and removing blood stasis, and preventing and treating cardiovascular and cerebrovascular diseases. Dried earthworms can be used as high-grade open bait for various fish and aquatic products; fresh earthworms are high-protein live baits; frozen earthworms are high-efficiency drug baits. All kinds of livestock and poultry animals often eat earthworms can improve the quality of meat, eggs and milk, reduce the amount of drugs, reduce drug residues, and reduce mortality. Fish fry farms, aquaculture farms, etc. often feed earthworms, which can make the seedlings strong, strong, and bright in color. Earthworms can also be used as traditional Chinese medicine, which has diuretic, analgesic, antiasthmatic, antihypertensive, antipyretic, and anticonvulsant effects. Earthworms contain dioronin, dioronin, vitamin B complex and other components, which can extract protease, lumbrokinase, worm fibrinolytic enzyme and other biological drugs.

The existing large-scale cultivation of earthworms in the market has not been intensive, industrialized or family-oriented, which has affected the survival rate and growth rate of earthworms. At the same time, in some mountainous areas, the land is small and the population is large, and the hard land is not suitable for the cultivation of earthworms. The vermiculture industry in the area must be restricted.

【Content of invention】

The object of the invention of the present invention is: aiming at the problems mentioned above, a method for cultivating earthworms with waste bacteria bags is provided, the method re-uses the waste, protects the environment, and the obtained earthworms have high yield, excellent quality, and no Poisonous, easy to manage.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

A method for cultivating earthworms with waste bacteria bags, comprising the following steps:

1) Preparation of breeding substrate: Mix waste bacteria bag, cow dung, straw and EM bacterial liquid in proportion, carry out fermentation and decompose, add Vitex vitex leaf extract after decomposing, mix well, and obtain earthworm culture substrate;

2) Earthworm bed laying: laying the prepared earthworm breeding substrate in the culture pond or culture box, the laying height is 30-50cm, and adding water to adjust the humidity, keeping the water content at 60-70%;

3) Earthworm inoculation: select healthy and lively earthworms with good varieties, and inoculate them on the bed with an amount of 2 to 3 kg per cubic meter;

4) Daily management: control the indoor temperature at 15-32°C on weekdays, and the humidity at 70%-75%. At this time, it can grow and reproduce well; Turn the litter once a day, turn the upper and lower layers of litter, and exchange positions;

5) Harvesting of earthworms: Scrape off the vermicompost layer by layer under the light, drive the earthworms to drill into the lower layer of the culture bed, collect the earthworms in the lower layer of the culture bed, place them on a large basket with an aperture of 3-5 mm, put a collection container under the basket, and place them under the light. Next, earthworms automatically drill into the container under the sieve to obtain earthworms.

Further, step 1) the preparation method of the cultivation substrate is: mix 60-80 parts by weight of waste bacteria bag, 30-50 parts by weight of cow dung, 20-30 parts by weight of straw and 1-3 parts by weight of EM bacteria solution in proportion, Carry out fermentation and decomposing, add 0.5-1 weight part of vitex leaf extract after decomposing, mix well, and obtain earthworm breeding substrate.

Further, the fermentation temperature is controlled at 50-60° C., and the fermentation time is 10-15 days.

Further, in step 1), the straw is selected from one or more of corn straw, wheat straw, rice straw and soybean straw.

Further, in step 1), the extract of Vitex leaves is prepared according to the following method: take Vitex leaves and pulverize them, add ethanol with a volume fraction of 30-50% to extract at 70-80°C, filter, recover ethanol from the filtrate, and then concentrate The relative density is 1.10-1.12 at 60°C, and the Vitex leaf extract is obtained.

Preferably, the Vitex leaf extract is prepared according to the following method: Take Vitex leaves and grind them, add 35% ethanol to extract at 70-80°C for 2 hours, filter, recover ethanol from the filtrate, and then concentrate to 60°C. The density is 1.11, and the extract of Vitex vitex leaves is obtained.

In summary, owing to adopting above-mentioned technical scheme, the beneficial effect of the present invention is:

(1) The unique earthworm breeding substrate is used, which not only reuses the waste and protects the environment, but also contains rich nutrients and has good air permeability. The content of the same is less, which improves the growth environment of earthworms, reduces the morbidity and mortality, and increases the growth rate and output. In addition, it solves the problem that it is difficult to cultivate earthworms in some areas, makes the earthworm cultivation standardized and standardized, and promotes the development of the earthworm cultivation industry.

(2) Reasonable daily management methods promote the growth of earthworms, and the vermicompost removed during the period can be used for feeding poultry and aquatic animals or for plant fertilizer application, which has good by-product value.

(3) In summary, the breeding method has simple process steps, abundant raw materials, cheap and easy to get, convenient management, overcomes the environmental restrictions in areas that are not suitable for breeding earthworms, promotes the development of earthworm farming, and the earthworms produced are large, Bright color, high nutritional value, and good economic value.
