How to raise red worms? What conditions are needed for red insect culture?

Culture conditions: using natural water to raise and change the water once a day, it is necessary to choose a large diameter container. Control light source: a small 5-watt light bulb can be used as light source at night. Water quality control: the water depth is 3-5cm, and the water flow rate is 5-10 liters per second. Bait feeding: generally 3-4 days once, each time feeding manure 50-100kg per mu, mixing it with water and sprinkling it in the whole pond.

I. Culture conditions

1. Red insects prefer to live in micro-flow fertile water, so it is necessary to achieve this condition in artificial breeding, generally in the late spring and early autumn, when red insects float on the water surface, causing the water surface to be brownish red. It needs to be collected in a container.

2. If it is a small-scale aquaculture, you can take back the bottom mud and the red worm together, put it in a glassware, and then raise it with natural water. if it is raised with tap water, you need to put the tap water in the sun for 2-3 days.

3. When raising, you should change the water once a day, and take good cold protection measures at low temperature, so you can use a red wet towel to cover the container to moisturize, and the container needs to choose a large diameter, so that the red worm will surface to breathe, and if the mouth of the container is relatively small, it will be easy to die.

Second, control the light source

The light source of breeding red worms is very critical, because the red worms cannot be separated from the light, so the lights must not be turned off at night. If there is no light source at night, the red worms will be lazy to breathe for a long time, which can easily lead to death. Generally, a small 5-watt light bulb can be used as a light source at night.

III. Water quality control

The main results are as follows: 1. The water depth is 3-5cm. In spring, the water level can be slightly shallow in the daytime, which can increase the water temperature, while the water level can be properly deepened at night, which is beneficial to heat preservation and cold protection.

2. Red insects prefer micro-running water environment, if the current is too large, it will take away the nutrients and eggs on the culture medium, but also consume a lot of physical strength, which is not conducive to increase yield.

3. If the water flow is too small and is not conducive to the discharge of water and excreta, jiu can easily lead to the deterioration of water quality and death. According to practical production, a water flow of 5-10 liters per second is a better flow environment.

4. At the same time, red insects are sensitive to pesticides and harmful substances, which should be paid attention to in water quality management, and water sprayed with pesticides and industrial wastewater should not be used.

Fourth, bait feeding

1. Red insects mainly feed on organic detritus in the soil and like sweet and acidic bait very much. Poultry droppings and domestic sewage are all bait for red worms. Generally, in professional farms, rice bran, point saw, silt, pigeon dung and other raw materials are used to make feed after fermentation. If it is domestic breeding, it can be fed with yeast powder.

2. Feeding is also the key point of red worm production, a small number of times during feeding can increase the yield, usually once every 3-4 days, feeding manure 50-100kg per mu each time, mixing it with water and sprinkling it in the whole pool.

3. When feeding, we should pay attention to the amount of residual bait and not throw too much blindly, so as to prevent excessive organic matter in the water, which will lead to toxic substances in fermentation and affect the yield of red insects in the later stage.
