CATDOLL : CATDOLL: Do you need to ferment cow dung before raising earthworms? (Do you need to ferment cow dung before raising earthworms?)

1. How to breed earthworms with cow dung?

Cow dung is a good material for earthworm breeding. When using cow dung to breed earthworms, the cow dung selected must be fermented and dried. Feeding earthworms with such cow dung not only has good air permeability, but also will not ferment and burn the earthworms. Before feeding, the cow dung should be expanded with water, and then squeezed to remove excess water. When the cow dung can be held in a ball and a small amount of water can be squeezed out from the fingers (the relative water holding capacity is 70% at this time), it can be fed into the bed. The feed can be covered on the breeding bed in a full layer, and there is no need to worry about the earthworms being suffocated or burned.

Using cow dung to breed earthworms: First, the color is red, and the color is vermilion, which is bright and eye-catching. Second, the smell is fishy, ​​and the smell is unique and pungent. Third, the meat is firm, with less water content, and can withstand fish pecks. Fourth, it is small, like a matchstick, and of moderate size. Fifth, it is fresh and alive, hanging on the hook, swinging and tumbling. Another biggest advantage is that it grows and reproduces quickly. Under the conditions of a suitable temperature of 15-25℃ and a relative water holding capacity of 70%, the reproduction volume can be more than doubled in 15-20 days.

2. How to deal with dry cow dung to raise earthworms?

If you want to breed earthworms with cow dung, you need to ferment it. You can use Lebeifeng feces feed fermentation agent to ferment it. The fermentation method is very simple. Just mix the bacteria with cow dung evenly. If you want to breed earthworms, it is best to add some grass powder and straw powder. After mixing the raw materials, add water and pile them into a large pile for fermentation. Fermented cow dung breeding earthworms grow fast.

3. How to raise earthworms using cow dung?

When breeding earthworms with cow dung, the selected cow dung must be fermented and dried. Using such cow dung for autumn drinking not only has good air permeability, but also does not burn the earthworms during fermentation.

Before feeding, dry and fresh cow dung should be dispersed with water. Then squeeze out excess water. When the cow dung can be held in a ball and a small amount of water can be squeezed out from the fingers, the relative water holding capacity is 70%. It can be fed into the bed, and the feed can be covered on the feeding bed throughout the process. There is no need to worry about the earthworms being suffocated or burned. Cow dung is used to breed earthworms. First, the color is red, which is bright and eye-catching. Second, the smell is fishy, ​​which is unique and pungent.

The third is meat frying. It has low water content and can withstand fish pecks. The fourth is a small matchstick of moderate size.

The fifth is freshness. Hang it on the fish hook.

Another great benefit of rocking and tumbling is that it grows and reproduces quickly. Under the conditions of room temperature of 15-25 degrees and relative water holding capacity of 70/700, the mass of the three plants can be more than doubled in 15-20 days.

4. How to ferment cow dung to raise earthworms?

1. Feed preparation:

Fermentation: Use rice straw or stalks to spread a 10-15 cm thick layer of dry material, and then spread 4-6 cm of manure on the dry material and repeat 3-5 layers. Use a spray bottle to spray water on each layer until the water seeps out. If garbage is used, pile up one layer of garbage and one layer of manure.

There is no limit to the length and width, and it should be covered tightly with a film. In the season with higher temperatures, it should be turned over every 7 days. Generally, the fermentation of the feed is completed after 3-5 times of turning over.

After the feed is fermented, test the pH value. Earthworm feed generally requires an appropriate pH value of 6-7.5, but the pH value of many animal and plant wastes is often higher or lower than this value.

When the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer; The scientific proportion of feed is the most effective way to increase the yield of cultured earthworms. 2. The above formula example requires:

① 50% cow dung, 50% pulp sludge;

② 100% cow dung or 100% mixture of all livestock dung;

③ 20% each of cow dung, pig dung, and chicken dung, and 40% of rice straw;

(Note: Chicken manure needs to be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will all escape or die.)

5. Technology of breeding earthworms with cow dung?

Fresh cow dung can be used directly to raise earthworms without fermentation. The effect of raising earthworms will be better if rotten fruits, rotten vegetable leaves, etc. are mixed with cow dung.

First, pile the cow dung into a 2-meter-long, 1-meter-wide, and 35-cm-high (thick) pile. Use an iron rake to loosen the top cow dung every day. The cow dung that has been dried to 50% needs to be loosened to a thickness of about 5-8 cm. When it is about 50% dry, you can put in earthworms. Each pile of dung can contain 30,000 egg-laying earthworms. Collect the earthworm manure and cocoons every 10 days and open another pile for incubation. Take out the cocoons every 10 days and open another pile for incubation to ensure that the size and specifications of each batch of earthworms are consistent. During the breeding period, if the earthworm manure is found to be dry, spray EM water in time, and mix EM with clean water or rice washing water or rice soup in a ratio of 1:5 and spray. Generally, spray once every 3-5 days. The earthworms raised by the above method grow fast and produce more and larger cocoons. Note that poultry and livestock manure must be fermented with EM or dried in the sun and mixed with a water content of about 60% before it can be used to raise earthworms.

6. How to breed earthworms with cow dung?

1.

Choose fermented and dried cow dung.

Feeding earthworms with such cow dung not only has good air permeability, but also will not ferment and burn the earthworms

2.

Use water to expand the dry cow dung, then squeeze out the excess water. When the cow dung can be held in the hand and a small amount of water can be squeezed out from between the fingers (the relative water holding capacity is 70% at this time), you can start feeding.

3.

The feed can be covered in a full layer on the breeding bed without worrying about the earthworms being suffocated or burned.

7. Can cow dung be used to raise earthworms?

Using cow dung to breed earthworms is not only the best choice for "turning waste into treasure", but also opens up a new way for the comprehensive utilization of cow dung. The method is: first mix cow dung with feed residues to compost until the physical and chemical indicators required for earthworms to lay eggs, hatch and grow are met, then spread the compost on the ground at an appropriate thickness, put in earthworms and let them breed.

Fresh cow dung can be used directly to raise earthworms without fermentation. If there are rotten fruits and vegetables, etc. mixed with cow dung, the effect of raising earthworms will be better. First, pile the cow dung into a dung pile with a length of 2 meters, a width of 1 meter, and a height (thickness) of 35 centimeters. Use an iron rake to loosen the cow dung on the top every day, and put in earthworm seeds when it is about 50% dry. Each pile of dung can be put into 30,000 egg-laying earthworms. Collect the earthworm manure and earthworm cocoons every 10 days and open another pile for hatching. This ensures that the size and specifications of each batch of earthworms are consistent.

If the earthworm manure is dry during the breeding period, spray em water in time, and mix em with clean water or rice washing water or rice soup in a ratio of 1:5 and spray it. Generally, spray it every 3 to 5 days. The earthworms raised by the above method grow fast, and the cocoons produced are large and numerous. But please note: poultry and livestock manure must be fermented with em or dried in the sun and mixed with a water content of about 60% before it can be used to raise earthworms.

Used cow dung can be used as fertilizer and applied directly to the field. After being treated with earthworms, the content of total nitrogen, available nitrogen, total phosphorus and organic matter in the cow dung will increase.

The growth and reproduction activities of earthworms accelerate the decomposition and transformation of nutrients in cow dung, and improve the fertility of cow dung as an organic fertilizer.

Cow dung can improve soil fertility, help increase soil water absorption and water holding capacity, and reduce runoff and soil loss.
