Earthworm culture technology and profit statement

Earthworm breeding technology: the puddle connected with the ditch can be used for reconstruction and breeding, adding livestock and poultry manure or farm manure 7.5-10kg per square meter, and seed worm 0.25kg-0.5kg, feeding feed such as cow manure, pig manure, straw and so on, the temperature should be kept at 20-27 ℃ during the breeding period, and the air humidity should be kept at 70% 80%. Generally, the net profit of raising earthworms per mu is about 15000 yuan.

1. Earthworm culture technology

1. Build potholes

(1) the puddles connected with the ditches can be used for reconstruction and aquaculture, with an area of 3-5 square meters and a water depth of 20-25cm. The bottom of the pits is made of loess or concrete with good water retention and set into the drain.

(2) then dig the fertile fish pond mud and lay it at the bottom of the pit with a thickness of 10cm, adding livestock and poultry manure or farm manure 7.5-10kg per square meter, and then adding fermented cake, bran and bran dregs, etc.

2. Introduction into the pit

Generally, planting worms 0.25-0.5kg per square meter, after the worm species are put away, cover a layer of plastic anti-mosquito net on the ditch, and then cover it with rain-proof materials such as plastic film and foam board, which can not only prevent enemy damage, but also protect against rain and moisture.

3. Feed

The feed is 100% or 50% of cow dung, 35% of pig manure, 150% of straw or 50% of pig manure, 50% of straw or weeds, 2-3 times a month, each time with a thickness of 10cm, requiring fresh and breathable feed.

4. Daily management

The temperature needs to be kept at 20-27 ℃, and the air relative humidity needs to be kept at 70% 80%.

Second, the cost of raising one mu of earthworms

1. The feed (cow dung, pig manure, straw, etc.) is 100m3, 20 yuan per cubic meter, totaling 2000 yuan.

2. The cost of self-propagating worm species 100kg is 20 yuan / kg, totaling 22000 yuan.

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

4. The total cost of hydropower tools is 500 yuan.

5. The total cost is 5100 yuan.

Income from raising one mu of earthworms

1. Earthworms

Generally speaking, the annual yield of fresh earthworms per mu is 2-3 tons, and the high one is up to 5 tons. according to the lower 2 tons, the market price is now more than 10000 yuan per ton (sales as bait can reach more than 30000 yuan per ton). If calculated at a lower rate of 10000 yuan per ton, it can also earn 20000 yuan.

2. Earthworm feces

Earthworm dung is 40 tons, 150 yuan per ton, totaling 6000 yuan.

3. Total

The total cost is 26000 yuan.

Fourth, the net profit of raising one mu of earthworms

26000 yuan-5100 yuan = 20900 yuan, if you hire workers to carry out large-scale breeding, you still need to pay the workers' wages. generally, one labor force can manage the earthworm breeding of 2 mu of land, calculated according to the monthly wage of 1000 yuan. the salary per mu is about 6000 yuan, and the actual profit is about 15000 yuan.
