CATDOLL : CATDOLL: The latest construction standards for red worm farms (the latest version of the construction standards for red worm farms)

1. Do you need seedlings to raise red worms?

To cultivate red worms, you need to plant seedlings

When breeding red worms, you need to build a pond in a place with sufficient water and clear water. The height of the pond should be about 1 meter and the area should be 10-30 square meters. Then drain the water in the pond and expose it to the sun. Then sprinkle quicklime or bleaching powder into the pond for disinfection, which is conducive to the healthy growth of red worms.

Red worms mainly feed on phytoplankton. When breeding red worms, you need to put the manure of livestock such as horses, cows, chickens and ducks into the pond as base fertilizer to make the soil more fertile. You also need to mix decomposed organic fertilizer or wood ash into the silt, which is conducive to the vigorous growth of algae and provide sufficient food for the red worms.

2. Introduce the habits and breeding techniques of red worms?

Breeding environment selection

The artificial breeding of red worms is very important for the choice of environment. If the environment is not chosen well, all the previous efforts will be wasted. Red worms like to live in a dark and humid environment without direct sunlight and calm water. Therefore, it is advisable to choose a quiet and dark place for breeding red worms, such as under the shade of trees in front of and behind the house, abandoned ditches and canals, etc.

Construction of breeding ponds

The highest yield of artificial breeding of red worms is achieved by pond breeding. The breeding pond can be built into a cement pond with a length of 20 meters, a width of 1.5 meters, and a depth of 0.3 meters. After the cement pond is built, it must be de-alkalied before it can be used. The method is: fill the cement pond with water, sprinkle superphosphate (sprinkle 1 kg of superphosphate per cubic meter of water) and soak for 3 days. After de-alkali, spread a layer of fermented farmyard manure on the bottom of the pond, and then spread a layer of pond mud.

Collection of red worms

There are two ways to obtain brood worms for artificial breeding of red worms. One is natural reproduction, which is to allow midges to lay eggs and reproduce in the breeding pond in spring and autumn every year. The other is to collect adult worms artificially.

Red worms can be found everywhere in the southern region, and most artificial breeding is done by collecting them from the wild.

The best time to collect red worms is in spring and autumn, with the best time being April to May in spring and October in autumn. In the wild, in ditches, lakes, and ponds where water has been stagnant for a long time and has poor water quality, when you see the water is brown-red, it means that red worms are gathering on the water surface, and you can collect a lot of red worms.

Stocking density

The collected red worms are directly placed in the breeding pond for feeding. The water level is maintained at about 0.2 meters and the stocking density should be moderate. If the density is too high, the dissolved oxygen content in the water will be insufficient and food shortage will occur.

Feeding

Red worms are omnivorous and can be fed with a lot of food. In addition to the organic matter produced by farmyard manure in the breeding pond, you can also feed some easily rotten organic debris, such as vegetable leaves, rice bran, sawdust, etc. If it is a large-scale breeding, you can prepare special feed yourself, mix rice bran, banana peels, sugarcane bagasse, sawdust, pigeon manure or chicken manure with pond mud, and feed it after sufficient fermentation. Feed it once every 3 days, and feed it once at 100 catties/mu.

manage

Although red worms like to grow in fertile water and do not require high water quality, they still need to change water during artificial breeding. The frequency of water changes can be determined according to the water conditions in the breeding pond. If the water quality is particularly poor, the water color is black, and the water body smells, the water needs to be changed. You cannot use tap water or clear spring water to change the water. You can use natural water from the weir pond, take it back and place it for 2 days before putting it into the pond. Pay attention to avoid light. If the sunlight is strong during the day, you can build a shed or use branches to shade it.

3. How big is the site and funds needed for whole insect breeding?

It costs about 400 million yuan to raise one acre of red worms, of which the cost of renovating the breeding pond is about 30,000 yuan, the cost of seedlings is about 5,000 yuan, and the cost of feed and other costs is about 5,000 yuan. However, the cost can be reduced to less than 10,000 yuan from the second year.

4. How to breed and reproduce red worms?

Red worms grow best in fertile water with steady water flow. When breeding red worms artificially, you need to build a cement pond with an area of ​​10-50 square meters. The depth of the water layer in the pond should be kept between 3-5 centimeters, and the bottom of the cement pond should be covered with silt rich in organic matter.

5. What are the breeding techniques for red worms?

1. Breeding pond: Bloodworm breeding is generally carried out on a large scale, so a breeding pond is needed. The number of bloodworms to be put in can be determined by the size of the breeding pond, and the water depth. When breeding bloodworms, the water should not be too deep. Generally speaking, 20 to 30 centimeters is more appropriate. In addition, some silt needs to be placed at the bottom of the pond, where bloodworms like to move around.

2. Food: The main food of red worms is plankton and organic debris in the water. When the water is rich in nutrients, the growth rate of red worms will be fast. Therefore, it is best to add some fermented fertilizer to the water regularly, so that the nutrients in the water will be richer. 3. Water quality: It is more appropriate to use river water or pond water to breed red worms, because such water is closer to the native environment of red worms, but tap water is more convenient. But don't use tap water directly. It is best to expose them to the sun for two or three days and wait until the chlorine in them is basically removed before using them. Red worms do not have high requirements for water quality, but water quality is closely related to dissolved oxygen, so water changes must also be done well.

6. What conditions are needed for red worm breeding?

A: 1. Breeding conditions

1. Red worms prefer to live in micro-flowing fertile water, so this condition must be met during artificial breeding. Generally, in late spring and early autumn every year, it is the season when red worms reproduce in large numbers. At this time, red worms will float on the water surface, causing the water surface to be brown-red, and they need to be collected in containers.

2. If it is a small-scale breeding, you can take back the bottom silt and red worms together, put them in a glass container, and then use natural water for breeding. If you use tap water for breeding, you need to expose the tap water to the sun for 2-3 days first.

3. When raising fish, you need to change the water once a day, and take anti-cold measures when the temperature is low. You can cover the container with a red wet towel to keep it moist. The container needs to be large-diameter so that the red worms will float to the surface to breathe. If the container mouth is relatively small, they will easily die.

2. Control the light source. The light source is very important for breeding red worms, because red worms cannot live without light, so the lights must not be turned off at night. If there is no light source at night, the red worms will be too lazy to breathe and easily die. Generally, a 5-watt small bulb can be used as a light source at night.

3. Water quality control

1. The water depth should be 3-5cm. When breeding in spring, the water level can be slightly shallower during the day to increase the water temperature, and the water level can be appropriately deepened at night to help keep warm and prevent cold.

2. Red worms prefer micro-flow water environment. If the water flow is too strong, it will take away the nutrients and eggs on the culture medium. It will also consume a lot of the red worms' physical strength, which is not conducive to increasing production.

3. If the water flow is too small, it will not be conducive to the discharge of water and excrement, which will easily lead to deterioration of water quality and cause death. According to practical production, a water flow of 5-10 liters per second is the best water flow environment.

4. At the same time, red worms are sensitive to pesticides and harmful substances. Pay attention to this when managing water quality. Do not use water that has been sprayed with pesticides and industrial wastewater.

4. Feeding

1. Red worms mainly feed on organic debris in the soil and are very fond of sweet and sour bait. Poultry manure, domestic sewage, etc. are all baits for red worms. Generally, in professional farms, rice bran, sawdust, silt, pigeon manure and other raw materials are fermented to make feed. If it is a family farm, you can use yeast powder to soak in water and feed it.

2. Feeding is also a key point in red worm production. Feeding in small amounts and multiple times can increase production. Generally, feed once every 3-4 days, with 50-100kg of manure per mu each time. Mix it with water and sprinkle it throughout the pond.

3. When feeding, pay attention to the amount of leftover bait and do not feed too much blindly to prevent excessive organic matter in the water body, which will cause fermentation and produce toxic substances, affecting the production of red worms in the later stage.

7. How much does it cost to raise red worms per acre?

Site cost Bloodworm breeding ponds are usually built with bricks, and the bottom is smoothed with cement mortar. The pond is rectangular, preferably small rather than large, and 40 cm high. The site reconstruction fee is generally 30,000 yuan/mu, but from the second year onwards, there is no need for site reconstruction fees, which means that the breeding cost will be at least 30,000 yuan/mu less from the second year onwards. Seedling cost There are two main ways to obtain bloodworm seedlings. One is to collect wild bloodworms in the wild by yourself, which has the advantage of low cost.
