Profit and cost of black water gadfly culture, the use of black water gadfly

The profit and cost of black water gadfly culture: the breeding cost is about 5000 yuan, and according to the calculation of the farming area of 200m ²per household, using the method of combined transformation of black water gadfly and microorganism, the dry powder of protein feed raw material can be produced about 20 tons. Microbial fertilizer is about 100 tons, and the profit is about 100000 yuan. The use of black water gadfly: can produce organic fertilizer and feed, can deal with organic waste, can be used to treat burns, can produce biodiesel.

I. profit and cost of black water gadfly culture

1. The feeding method of the black water gadfly is relatively simple. Generally, it can be raised in greenhouses or idle houses, and both the north and the south can be raised. The breeding cycle is short, the return on investment is fast, and the breeding cost is about 5000 yuan for many years. The female lays eggs each time, and the cycle is only 7-10 days. The vitality is relatively strong, and there is no risk of epidemic infection.

2. Now, with the continuous improvement of the national requirements for the treatment of farm feces, the treatment of feces with black water gadfly has become a better choice for farmers. Every year, black water gadfly larvae are snapped up by local farmers and feed factories in other counties and cities. According to the calculation of the farming area of 200m ²per household, using the method of combined transformation of black water gadfly and microorganisms, about 20 tons of protein feed raw material dry powder can be produced. The microbial fertilizer is about 100t, and the profit is about 100000 yuan.

Second, the use of the black water gadfly

1. Can produce organic fertilizer and feed

Scientific research shows that the feces treated by the black water gadfly can become high-quality organic fertilizer. compared with other protein feed, salmonella and other harmful bacteria can hardly be detected in the black water gadfly, so adding the black water gadfly to the feed can effectively improve the quality of the feed, but when the black water gadfly is used as feed, it still has to be sterilized before it can be put on the market.

2. Organic waste can be treated.

The main results are as follows: (1) the black water gadfly likes to eat the feces of birds and garbage in daily life, and likes to live in a relatively humid environment, so it can be used to deal with organic waste, and some studies have shown that the feces left by livestock treated by the black water gadfly, the content and species of harmful bacteria decreased significantly.

(2) at the same time, the content of organic matter in the pollutants is directly proportional to the waste reduction index of the black water gadfly, and the texture of the faeces treated by the black water gadfly will become soft and odorless, and can generally be used as organic fertilizer, so the black water gadfly can treat organic waste and turn it into a treasure at the same time.

2. It can be used to treat burns.

The black water gadfly is also widely used in medicine. The larvae of the black water gadfly can be used to treat burn and wound healing, as well as anti-inflammatory and analgesic effects. It is a kind of medical resources and medicinal insects.

3. Biodiesel can be produced

The black water gadfly is rich in fat and is a high-quality raw material for the production of biodiesel. China is a big country in the use of energy. If the black water gadfly is used to produce biodiesel, it can effectively solve the problem of China's energy shortage and provide a reliable method for China's energy development.
