Cultured earthworms can be used not only as bait for fishing, but also as breeding feed or medicine. Now, a catty of earthworms can be sold for about 10 yuan, and last year it sold more than 600 tons, which drove several cooperative farmers in Xinmaqiao Town and Wangzhuang Town here to breed together, mainly sold to Jiangsu, Zhejiang and Shanghai. This is an earthworm in hand, and their nutrient is cow dung, which may be uncomfortable for many people.
