How much does it cost to raise earthworms?

Earthworm farming has not only opened up a new source of animal protein feed for the development of livestock, poultry and aquaculture, but also found a new way for cities to purify the environment and deal with public hazards. and with the in-depth study of earthworms can also provide valuable raw materials for food, medicine and other industries, so earthworm breeding is a good way to get rich, let's take a look at how much money is needed to raise earthworms.

How much does it take to raise earthworms?

1. Use bait (cow dung, pig dung, chicken manure, raising mushroom feet) 100m3, 20 yuan per cubic meter, a total of 2000 yuan.

2. The self-propagated worms are 100kg, each kilogram is calculated at a cost of 20 yuan, a total of 2000 yuan.

3. The land occupation fee is 1 mu, 600 yuan per mu, 600 yuan in total.

4. The amount of hydropower tools is 500 yuan.

5. Raising one mu of earthworms requires an investment of 5100 yuan.

How much money can you earn from raising earthworms?

1. Earthworms: generally speaking, the yield of fresh earthworms per mu is 20.3 tons, and the highest is 5 tons. According to the lowest two tons, the current market price is more than 10000 yuan per ton, and the income can be calculated at 20000 yuan according to the lowest 10000 yuan per ton.

2. Earthworm feces: 40 tons, 150 yuan per ton, 6000 yuan.

3. Total: the income of raising one mu of earthworms is 26000 yuan.

4. Profit: 26000 yuan-5100 yuan = 20900 yuan. If you hire workers to carry out large-scale breeding, you still need to pay the workers' wages.

What are the methods of collecting earthworms?

1. Irrigation capture method: earthworms are afraid of stagnant water, so they can be caught out of holes by irrigation, and can also be caught in paddy fields during spring ploughing.

2. Stacking trapping method: stack the fermented and ripe feed in the place where earthworms are to be trapped (such as the edge of the field, vegetable garden).

3. Digging method: the method is simple, but the effect is poor, this method is suitable for small-scale breeding.

4. Chemical trapping: sprinkle potassium permanganate solution or formaldehyde solution on the place where earthworms are collected, and the earthworms will soon climb up to the ground.

Expansion: the technology of raising earthworms with cow dung

1. Feed formula: 50% of cow dung, 50% of pulp sludge or 100% of cow dung or 100% of all livestock manure or 20% of cow manure, 20% of chicken manure, 40% of rice straw scraps, chicken manure must be raised with maggots or placed for more than 1 year before raising earthworms, otherwise all the earthworms will escape or die.

2, feed fermentation: straw and straw first spread a layer of dry material with a thickness of 10 cm to 15 cm, and then spread 4 cm to 6 cm dung, repeating 3 to 5 layers, spraying water at each layer until the water seeps out, turning once every 7 days in the higher temperature season, generally turning 3 to 5 times to complete the feed fermentation work.

3, feed preparation: the PH value of earthworm feed is tested after fermentation, the suitable PH value is generally required to be 67.5, 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.

4. Culture density: the number of earthworms raised by cow manure should be controlled within 10, 000 per square meter, the production of earthworms should be 3 kg per square meter (2 ~ 31000), 30, 000 young worms per square meter in the early stage, and decreased to 20, 000 in the later stage.

5. timely feeding: usually earthworms can turn all cow dung into earthworm dung in about 20 days. when feeding, the new material can be covered on the basis of the original feed, and the amount of feed should be determined according to the food intake of earthworms, and the feed should be laid evenly, plus rice straw. often watered and moisturized.

6. reasonable watering: in order to ensure the normal growth of earthworms, especially in summer, water should be watered at least once a day, the water should not be polluted, the water flow should not be too large, it must be watered thoroughly so that the upper and lower layers can be connected, and it is best to choose the lower temperature in the morning or evening.
