CATDOLL : CATDOLL: How many times a year should I change the water when raising earthworms and cow dung? (How many times a year should I change the water when raising earthworms and cow dung?)

1. Can cow dung be used to raise earthworms?

Answer: You can use cow dung to raise earthworms.

It is okay to use cow dung to raise earthworms, as there are undigested substances in cow dung that can be absorbed by earthworms. However, you cannot use all cow dung to raise earthworms. Only 35-50% can be used, and other feeds should be added, such as cornmeal, soybean meal, vegetable leaves, minerals and vitamins, etc. Raising earthworms is a technical job that requires carefulness and patience. If you are a fisherman, there will be no problem raising earthworms, because you do it out of interest and hobby, and you will work hard to raise them well.

2. 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.

3. How to breed earthworms with cow dung?

1. Feeding: timely feeding can promote the rapid growth of earthworms. The thickness of the manure should be 5-10 cm, and do not cover the bed completely.

2. Earthworm breeding temperature: 5-40℃. Thicken the bed to 40-50cm in winter, cover with straw and black film. Water every day in summer. Loosen the bed before adding manure to increase the air permeability of the earthworm bed, add 5-10cm of manure, harvest once a month in summer, harvest once every 1.5 months in spring and autumn, and replenish feed in time after harvesting.

3. Bait: The best baits are cow dung, pig dung, horse dung, sludge, rabbit dung, pig, sheep, rabbit dung plus straw.

5. Harvesting earthworms

Move the cow dung away, move the dense areas by hand, put the earthworms and soil into the basin, then pour it on the flower oil paper, spread it flat, and use the principle that earthworms are afraid of light to hang the soil layer by layer. What remains are the earthworms.

4. Do you need to add soil when raising earthworms using cow dung?

The best bait for earthworms is cow dung, pig dung, horse dung, sheep dung, rabbit dung, pig, sheep, rabbit dung mixed with straw and rice straw for fermentation, no need to add soil. 1. Feeding of bait: timely feeding of earthworms with sufficient bait is an important measure to ensure the rapid growth of earthworms. The bait is thrown in a pile with a thickness of 10 cm. Do not cover the bed surface completely and do not seek flatness to separate the earthworms.

2. Temperature for earthworm breeding: The best temperature is 15-25℃. In winter, use thickened breeding beds to 40-50 cm, cover the bait with straw, and then add plastic sheeting to keep warm and moisturize. In summer, try to water once a day to cool down. Stage breeding: It can be divided into seed groups, breeding groups, and production groups. Feed thinly and turn the beds frequently. Feed twice a month. Turn the beds before feeding. The thickness of each feeding is 10 cm. Keep the bait fresh and breathable at all times. Harvest in time: Harvest once a month in summer, and once every 1.5 months in spring and autumn. Replenish feed in time after harvesting. Rotation and update: The seed earthworms should be updated once a year, and the breeding beds should be replaced once a year to ensure the vigor of the earthworm population and prevent the decline of the earthworm population due to natural development.

Notes on raising earthworms: 1. Likes warmth: 15℃-25℃ is the best temperature. In order to create the best temperature, cover the greenhouse with plastic sheets in winter, cover with straw in summer, sprinkle water to cool down, hibernate at 0℃-5℃, freeze to death below 0℃, die above 40℃, and stop growing above 32℃. In Beijing, cover the greenhouse with plastic sheets on October 25th, and remove it on April 10th of the following year. In this way, the earthworms will grow to December 20th, and then to February 10th of the following year, they are basically dormant. From February, prevent the earthworms from escaping due to high temperature. Pay attention to uncover the plastic sheets in time after 10 days and gradually turn to the optimal temperature. At this time, pay special attention to the high temperature plastic sheets. This is the most difficult time. During the day, uncover the plastic sheet around the plant, cover it in the morning and evening, and water it in time to keep it moist. From March to June 10 is the peak period of spring spawning for earthworms. During the high temperature period, you should prevent heatstroke and cool down. It is best to water it once a day. From August 20 to June 10 to August 20 is the summer season, and the plant will gradually enter dormancy. At the end of September, it is the second peak period of spawning for earthworms.

2. Like moisture and afraid of dryness: The water content in the body of earthworms is about 80%, and the water content of bait is required to be 60%-80% (based on the water dripping from the fingers when holding the bait in the hand). Therefore, the moisture content of the breeding bed is required to be above 60%. In this way, water must be poured once a day or every 1-2 days. The water should not be too much, but it must be poured thoroughly and connected to the lower layer of material. The watering time is noon in winter, evening in summer, and daytime in spring and autumn.

3. Like darkness and afraid of light: earthworms hide during the day and come out at night. They can be seen foraging under the moonlight. The breeding bed should be covered with straw to keep it moist and shaded.

4. They like air and quietness. Loose bait is good for the growth of earthworms. Our experience over the years is to turn the bed over (about 20 cm thick) before feeding to increase ventilation. This is very important. Over the years, we have found that there are very few earthworms at the bottom of the bed soil, but there are still baits. The main reason is the lack of air, which is not good for the growth of earthworms.

5. How often should earthworms 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.

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

There are four key points in the breeding technology of earthworms with cow dung. The first point is the feed formula. When feeding, 50% of cow dung can be mixed with other feces to feed earthworms;

The second point is feed fermentation. Use straw or stalks to spread a layer of dry material about 10-15 cm thick for fermentation.

The third point is feed preparation. After the feed is fermented, the pH value can be tested;

The fourth point is the breeding density. The number of earthworms raised with cow dung should be controlled within 10,000 per square meter.

7. 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.
