CATDOLL : CATDOLL: How often is it best to feed earthworms with cow dung? (How often is it best to feed earthworms with cow dung?)

1. How often do earthworms need to be replaced with cow dung?

This depends on the number of earthworms. Generally, if there are less than 100 earthworms, the cow dung should be replaced every three days, and if there are more than 100 earthworms, the cow dung should be replaced every day or so.

Example of formula for raising earthworms with cow dung:

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 dung must 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.)

④ Corn stalks or rice straw, peanut stalks, rape stalks, single or mixed 40%, pig manure 60%;

⑤ Horse manure 80%, leaves and rotten grass 20%; ⑥ Pig manure 60%, sawdust 30%, rice straw 10%;

⑦ Organic waste 70%, animal manure 30%; or all waste 100%.

⑧ Various feces 60%, sugarcane bagasse 40%; and so on.

2. How often should earthworms be added to one acre of land to add manure?

It takes about 20 tons of cow dung to make a worm bed for 1 mu of land in the early stage. The worm bed is only made once and does not need to be made again in the future. It is a place for earthworms to get food and also a place for them to live. Therefore, it is very important to make a good worm bed, and then you can plant seedlings. In the future, you can feed 3-5 tons of fresh cow dung every month. The price of cow dung varies from place to place. Some are free, some are dozens of yuan per ton, and some are more than 100 yuan per ton.

3. What is the simplest way to raise earthworms using cow dung?

1. Feed formula: When feeding, use 50% cow dung, 50% pulp sludge, or 20% each of cow dung, pig dung, chicken dung, and 40% rice straw to feed the earthworms. Chicken manure must be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will escape or die.

2. Feed fermentation: Use straw to spread a layer of dry material with a thickness of about 10-15 cm, and then spread 4 cm of manure on the dry material and repeat 3-5 layers. Use a watering can to spray water on each layer until the water seeps out. In high temperature weather, you can turn it over every 7 days. Generally, the feed fermentation work is completed after turning it over 3-5 times.

3. Feed preparation: After the feed is fermented, the pH value can be tested. The suitable pH value of earthworm feed is generally 6-7.5, but the pH value of many animal and plant wastes will be higher or lower than this value. If the pH exceeds 9, acetic acid, salt or citric acid can be used as a buffer.

4. How to raise earthworms using cow dung?

First, pile the cow dung into a 2-meter-long, 1-meter-wide, and 35-centimeter-high pile; use an iron rake to loosen the top dung every day. The dung that is loosened and dried to 50% should be about 5-8 centimeters thick. 30,000 laying earthworms can be placed in each pile of dung.

5. 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.

6. 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.

7. 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.
