Technology of raising earthworms with pig manure

Earthworm is a kind of creature that everyone is very familiar with. Earthworm can soften the soil and decompose harmful substances in the soil. It is a kind of beneficial insect. Earthworms can also be raised on a large scale as carnivorous feed, and many farmers will raise some earthworms to reduce their feed costs. Now there is a technology of raising earthworms with pig manure, so how can we use pig manure to raise earthworms? Let's take a look at it with the editor.

1. Pig manure fermentation

If pig manure has not been fermented, earthworms can not be raised, because the heat emitted by pig manure will burn earthworm eggs, resulting in breeding failure. First of all, it is necessary to ferment pig manure, mix it into pig manure with fecal starter, control the water content at about 65%, and carry out fermentation according to the original water content of pig manure. Pay attention to the fermentation temperature, turn the pig manure over when the temperature rises to about 65 degrees, lower the temperature and then carry out secondary fermentation to prevent the destruction of nutrients. Cover the plastic film during fermentation and give off the aroma of wine or white hyphae in about 12-15 days.

2. Set up a culture bed

Pig manure fermentation and then according to their own breeding quantity to set up a reasonable area of the fermentation bed, pig manure into the breeding bed stacked into a dung pile of about 30 cm. You can add an appropriate amount of cow dung to the dung pile, rake loose cow dung once a day to promote uniform exposure to the sun, and when 60% of cow dung is dry, you can begin to put earthworm species. Control the culture density and adjust it according to the changes of seasons, for example, it can be kept close in winter and reduced in summer. Put the earthworm seed and then cover with a layer of straw for moisturizing and heat preservation. If the earthworm shrinks, dies and other abnormal conditions, we should pay attention to whether the fermentation of pig manure is incomplete, and if so, it needs re-fermentation.

3. Feed selection

Pig manure breeding earthworms of course pig manure must be the most important feed for earthworms, and the quality of pig manure is also directly related to the success of earthworm breeding. First of all, we must control the density of pig manure, the density should not be too high, otherwise it will cause too much pressure on earthworms and affect the growth of earthworms. In addition, the permeability of pig manure should be strengthened, the water retention capacity should be improved, and the normal growth of earthworms should be ensured. Then take another fresh pig manure, mix it with forage, pour enough water to ensure that the humidity is more than 60%, and stack it together for fermentation as backup feed for earthworms.

4. Daily management

First of all, we should control the temperature and humidity of earthworm growth, the change of temperature and humidity has a great impact on the growth of earthworm. The temperature of earthworm growth is about 18 degrees, the lowest can not be less than 5 degrees, the highest can not be higher than 30 degrees, otherwise it will have a greater impact on earthworms, even 40,000 in serious cases. Humidity should be controlled at about 65%, the PH value of pig manure should be moderate, too high or low will inhibit the growth of earthworms. In the hot summer environment, we also need to irrigate small water once a day, the water can not be polluted, it should be watered thoroughly to ensure the normal growth of earthworms.

The above is a brief introduction to the technology of raising earthworms with pig manure, which is a very environmentally friendly method. Not only the pollution problem of pig manure is solved, but also the farmed pig manure can be used as fertilizer. And earthworms can be used as feed, traditional Chinese medicine and bait.
