Economic benefits of earthworm culture

Although earthworm culture started late in China, great attention was paid to its development from the very beginning. In recent years, the lack of animal protein has led to a sharp rise in feed prices. The economic benefits of most farms are not good, or even year after year losses, seriously affecting the development of the aquaculture industry. Earthworms are saprophytic invertebrates that feed on organic wastes. Many studies have proved that earthworms (powder) have high nutritional value and can be used as feed instead of fish meal. At the same time, earthworms are rich in amino acids and special ingredients, which are excellent food attractants needed by fish and many other aquaculture industries. Breeding farms use their own or nearby manure to produce earthworms to supply other animals, which can not only reduce the breeding cost, but also significantly improve the breeding effect.

In recent years, due to the rapid rise of rice field eel and other special aquaculture, coupled with the rise of leisure agriculture (especially fishing farms), there is an urgent need to use a large number of earthworms.

Annual expenditure on raising 1 mu of earthworms

1. Using bait (cow dung, pig dung, chicken dung, raising mushroom feet) 100m3, 20 yuan per cubic meter, 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. Total: 5100 yuan.

The annual income of raising 1 mu of earthworms

1. Earthworms: generally speaking, the annual 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 (sales as bait can reach more than 30000 yuan per ton). We can also earn 20000 yuan if we calculate it as a minimum of 10000 yuan per ton.

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

3. Total: 26000 yuan.

Net profit of raising 1 mu of earthworms

26000 yuan-5100 yuan = 20900 yuan, if you hire workers to carry out large-scale breeding, you also need to pay the wages of the workers. Generally speaking, a labor force can manage earthworm farming on two mu of land. if we calculate our monthly salary of 1000 yuan, we need to pay about 6000 yuan per mu of land, and the actual profit is about 15000 yuan.

Practice has proved that the dung produced by 30 cattle per day can raise earthworms for one mu, produce 20.3 tons of earthworms and 40 tons of earthworm manure per mu, and increase income by 15000 yuan. The income of each cow can be increased by 500yuan. In a county, if 15000 head of cattle can be used to raise earthworms, the income can be increased by more than 7000,000 yuan. It can form an industry and promote the development of the local economy. It can increase the income of 2000 farmers by nearly 4000 yuan. The development of worm farming can promote the development of cattle, pig, chicken and many other industries, and the two sides promote each other and develop together.
