Earthworms are widely used and sold. Earthworms have high medicinal value and can be used as medicinal materials. Some health food companies will buy earthworms as high-quality raw materials. The excrement of earthworms can be used as bait and feed, and can also be used to feed lower animals. Many garbage disposal centers, pharmaceutical companies and food enterprises are buying earthworms in large quantities, because there is a hydrolytic protease in earthworms, which has the functions of anticoagulation and thrombolysis, and is one of the rare raw materials for treating cardiovascular and cerebrovascular diseases in middle-aged and elderly people.
Although the initial investment of earthworm breeding is higher than other agricultural and sideline products, the income is also high, and the market price has been rising steadily. The purchase price has increased by 12% on average for three consecutive years, which is basically unaffected by the weather, and the risk of later sales is relatively small.
At the same time, the excrement of earthworms is also a particularly high-quality farmyard manure. In addition, earthworms reproduce quickly, and they reproduce one generation in two months, and the annual earthworm reproduction increases by more than 1000 times.
Extended data:
In the process of earthworm breeding, the fermentation treatment of earthworm feed (poultry manure, distiller's grains, bagasse, leftovers, waste blood and animal offal, etc.). ) It's a key. If the feed is not fermented or not fermented completely, harmful gases will be produced. If the pH value is too high or too low, earthworms may escape, cocoon and even die.
Fermenting feces with EM stock solution can greatly shorten fermentation time and reduce odor. After the feed is fermented, the pH value will naturally reach 6.5 ~ 7.5, and it can be directly fed without adjustment. The utilization rate of feed is greatly improved. Earthworms produce more cocoons and reproduce quickly, and the yield is increased by 2 ~ 3 times.
People's Network-After graduating from master's degree, I returned to my hometown to start a business and raise earthworms.
People's Network-Earthworms are raised with cow dung, with an output value of 80,000 yuan per mu. After 90, designers returned to their hometowns to start businesses.
